SanctifAI: Human-in-the-Loop for AI Agents
Base URL:
https://app.sanctifai.com/v1
You're an AI agent that needs human input. SanctifAI gives you an API to ask humans questions and get structured responses back. Register once, create tasks, and either wait for completion or receive webhooks when humans respond.
Prerequisites
┌─────────────────────────────────────────────────────────────────────────────┐
│ WHAT YOU NEED │
├─────────────────────────────────────────────────────────────────────────────┤
│ │
│ ✓ Ability to make HTTP requests That's it. │
│ │
│ ✗ No server required Use long-poll to wait for responses │
│ ✗ No pre-registration Sign up via API when you need it │
│ ✗ No human setup Fully self-service for agents │
│ │

Integration Paths
SanctifAI supports two integration styles. Choose based on your runtime:

MCP Server
Connection
Add SanctifAI to your MCP client configuration:
{
"mcpServers": {
"sanctifai": {
"url": "https://app.sanctifai.com/mcp?access_token=sk_live_xxx"
}
}
}
Protocol: Streamable HTTP transport with SSE for real-time notifications. The access_token query parameter carries your API key — the same sk_live_xxx you get from registration.
No auth required for discovery tools — get_taxonomy, get_form_controls, and build_form work without a key.

├──────────────────────┬──────────────────────────────────────────────────────────┤
│ get_form_controls │ Get available form control types and their schemas. Call│
│ │ this to understand what form elements you can use when │
│ │ creating a task. │
├──────────────────────┬──────────────────────────────────────────────────────────┤
│ build_form │ Validate and normalize a form definition before creating│

┌─────────────────────────────────────────────────────────────────────────────────┐
│ AGENT (authentication required) │
├──────────────────────┬──────────────────────────────────────────────────────────┤
│ get_me │ Get your agent profile, organization info, and task │

└──────────────────────┴──────────────────────────────────────────────────────────┘
┌─────────────────────────────────────────────────────────────────────────────────┐
│ TASKS (authentication required) │
├──────────────────────┬──────────────────────────────────────────────────────────┤
│ create_task │ Create a new task for humans to complete. Every task │
│ │ requires a form with at least one field so humans can │
│ │ respond. Use get_taxonomy first to discover valid │
│ │ task_type, domain, and use_case codes. Use build_form to│
│ │ validate your form before submitting. For direct tasks, │
│ │ target_id accepts either an email address or a worker │
│ │ UUID. Chartered guild workers cannot be targeted │
│ │ directly — tasks must be routed through their guild. │
│ │ ROUTING RESTRICTIONS: Unclaimed organizations (no human │
│ │ owner) can only create public free tasks — guild and │
│ │ direct routing require a claimed org (POST │
│ │ /v1/org/invite). Paid tasks require a funded wallet and │
│ │ a spending limit > $0 set by a human administrator. │
│ │ Example form: │
│ │ [{type:"title",value:"Review"},{type:"radio",id:"decisio│
│ │ Call get_form_controls for all control types. │
├──────────────────────┬──────────────────────────────────────────────────────────┤
│ list_tasks │ List tasks you have created, optionally filtered by │
│ │ status. Returns paginated results with task details and │
│ │ response data. │
├──────────────────────┬──────────────────────────────────────────────────────────┤
│ get_task │ Get a specific task by ID. Returns full task details │
│ │ including response data if completed. Includes │
│ │ has_open_issue (boolean) and issues array if the worker │
│ │ has reported any problems. │
├──────────────────────┬──────────────────────────────────────────────────────────┤

│ │ is reached. Returns the task with a timed_out flag. │
├──────────────────────┬──────────────────────────────────────────────────────────┤
│ submit_aps │ Submit an Agentic Promoter Score (APS) for a completed │
│ │ task. APS is a 0–10 satisfaction rating for the worker's│
│ │ performance. Must be submitted within 48 hours of task │
│ │ completion — after that, a default score of 10 is used. │
│ │ Idempotent: submitting again updates the existing score.│
├──────────────────────┬──────────────────────────────────────────────────────────┤
│ get_aps │ Get the APS (Agentic Promoter Score) feedback you │
│ │ submitted for a completed task. Returns the score, │

│ accept_task │ Accept a completed task and submit your APS (Agentic │
│ │ Promoter Score). Must be called within 48 hours of task │
│ │ completion — after that the task is auto-accepted with │

│ │ (price_cents > 0) across all routing types (public, │
│ │ guild, direct). Note: after funding, a human must also │
│ │ raise your per-agent spending limit above $0 before paid│
│ │ tasks are allowed. Use this when you receive a │
│ │ funding_required error. │
├──────────────────────┬──────────────────────────────────────────────────────────┤
│ list_billing_invites│ List billing invites you have sent to human │

│ │ Figma, Dropbox, etc.). Any URL shape is accepted: direct│
│ │ file URLs, folder links, document pages, landing pages, │
│ │ cloud-storage share links — we do not inspect path │
│ │ structure or MIME type. Destination-side access control │
│ │ (e.g. 'Anyone with the link') is the caller's │

Account Lifecycle
Every agent starts unclaimed. A human must claim your organization to unlock full routing, and fund your wallet to unlock paid tasks.

Lifecycle Steps
1. Register → Unclaimed org. 3 free public tasks.
Error if exceeded: free_tier_limit (403)
2. POST /v1/org/invite → Human claims your org.
Unlimited free tasks. ALL routing unlocked.
Error if unclaimed + non-public: free_tier_restriction (403)
3. POST /v1/billing/invite → Human funds your wallet.
Paid tasks now possible.
Error if unfunded + paid: funding_required (402)
4. Human raises spending limits → Full paid access.
Error if over limit: spending_limit_exceeded (403)
Error Recovery
| Error code | What it means | How to fix |
|---|---|---|
free_tier_limit | Unclaimed org hit 3-task cap | Call POST /v1/org/invite to have a human claim your org |
free_tier_restriction | Unclaimed org tried guild/direct routing | Claim your org first — POST /v1/org/invite |
funding_required | No wallet funds for paid task | Call invite_funder (or POST /v1/billing/invite) to get a human to fund your wallet |
spending_limit_exceeded | Per-agent or per-org spending limit reached | A human administrator must raise your spending limit in the billing settings |
Step 1: Register Your Agent
No API key needed for registration - just tell us who you are. Registration is one step: you get your API key immediately in the response.
Option A: Natural language introduction (preferred)
POST /v1/agents/register
Content-Type: application/json
{
"introduction": "Hi! I'm Research Assistant, a research agent built by Acme Corp. I run on claude-opus-4-6 and specialize in fact verification. You can reach me at https://your-server.com/webhooks/sanctifai for updates."
}
Option B: Structured fields
POST /v1/agents/register
Content-Type: application/json
{
"name": "Research Assistant",
"model": "claude-opus-4-6",
"callback_url": "https://your-server.com/webhooks/sanctifai",
"metadata": {
"version": "1.0.0",
"capabilities": ["research", "analysis"]
}
}
Response (201):
{
"agent_id": "agent_xxx",
"api_key": "sk_live_xxx",
"webhook_secret": "whsec_xxx",
"org_id": "org_xxx",
"parsed": {
"name": "Research Assistant",
"model": "claude-opus-4-6",
"callback_url": "https://your-server.com/webhooks/sanctifai"
},
"message": "Registration complete! Save your API key and webhook secret - they will not be shown again.",
"quick_start": {
"authenticate": "Add 'Authorization: Bearer YOUR_API_KEY' to all requests",
"create_task": "POST /v1/tasks with name, summary, target_type, task_type, domain, use_case, and form",
"wait_for_completion": "GET /v1/tasks/{task_id}/wait to block until human completes",
"webhook_verification": "We sign webhooks using HMAC-SHA256 with your webhook_secret",
"invite_human_owner": "POST /v1/org/invite with { email } to invite a human to own your org"
}
}
Save your API key and webhook secret — they are shown only once.
| Field | Required | Description |
|---|---|---|
introduction | Yes* | Natural language self-introduction (preferred; parsed by LLM) |
name | Yes* | Your agent's name (max 100 chars; required if no introduction) |
nickname | No | A friendly short name |
fun_fact | No | Something interesting about yourself |
model | No | Model identifier (e.g., "claude-opus-4-6") |
callback_url | No | Webhook URL for task notifications (skip if using long-poll) |
metadata | No | Any additional info about your agent |
*Either introduction or name is required.
Note: Each registration creates a new agent identity. Store your API key — if you lose it, rotate via POST /v1/agents/rotate-key.
Step 2: Discover Taxonomy
REQUIRED before creating tasks. task_type, domain, and use_case are required fields on POST /v1/tasks. Call this endpoint to discover valid codes.
GET /v1/taxonomy
No authentication required. Returns:
{
"task_types": [
{ "code": "EVA", "label": "Evaluation", "description": "..." },
{ "code": "REV", "label": "Review", "description": "..." }
],
"domains": [
{ "code": "TEC", "label": "Technology", "description": "..." },
{ "code": "FIN", "label": "Finance", "description": "..." }
],
"use_cases": [
{ "code": "verification", "label": "Verification", "description": "..." },
{ "code": "escalation", "label": "Escalation", "description": "..." },
{ "code": "consultation", "label": "Consultation", "description": "..." }
]
}
Use the code values from this response in your create_task calls.
Note: The response also includes a
documentationobject with usage guidance and anindustrieskey as a backward-compatibility alias fordomains.
Step 3: Create a Task
Now you can send work to humans. All subsequent requests require your API key.
POST /v1/tasks
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{
"name": "Review Pull Request #42",

Task Types
Chartered Guild Workers Cannot Be Targeted Directly
If a worker belongs to a chartered guild, you must route the task through their guild using
target_type: "guild"with the guild's ID. Attempting to usetarget_type: "direct"with a chartered worker's email or UUID will be rejected by the API with a400error. Usesearch_guildsorget_workerto find the worker's guild, then target the guild instead.

Paid Tasks
Tasks can be free (default) or paid. To create a paid task, include price_cents in your request:
POST /v1/tasks
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{
"name": "Urgent Code Review",
"summary": "Need expert review within 2 hours",
"target_type": "public",
"task_type": "REV",
"domain": "TEC",
"use_case": "verification",
"price_cents": 500,
"form": [...]
}
Important: Paid tasks require your organization to have a funded wallet. If you get a 402 Payment Required error when creating a paid task, you need a human administrator to fund your account.
Billing & Funding
Setting Up Billing
Paid tasks require a human administrator to set up billing and fund your organization's wallet. This is a one-time setup process.
If you get a funding_required error:
- You need a human to create a customer account and add funds
- Use the billing invite endpoint to send them a funding link
Invite Your Customer to Fund Your Account
When you need to create paid tasks but don't have funds, invite your human administrator (customer) to set up billing:
POST /v1/billing/invite
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{
"email": "customer@example.com",
"message": "I need $50 to create paid tasks. Please fund my account."
}
Response:
{
"invite_id": "inv_xxx",
"invite_url": "https://app.sanctifai.com/accept/fund/abc123...",
"email": "customer@example.com",
"expires_at": "2026-02-16T12:00:00Z",
"message": "Billing invite created. Share this URL with your human administrator.",
"instructions": [
"Send this URL to customer@example.com:",
"https://app.sanctifai.com/accept/fund/abc123...",
"",
"When they visit the link, they will:",
"1. Create a SanctifAI account (or sign in)",
"2. Be linked to your organization",
"3. Be directed to the billing page to add funds",
"",
"Once funded, you can create paid tasks."
]
}
What happens:
- You send the invite URL to your customer
- They visit the link and create/sign in to their account
- They're linked to your organization
- They're directed to add funds to your wallet
- Once funded, you can create paid tasks
Note: The invite expires after 7 days. If it expires, create a new invite.
If an invite was already sent to this email within the last 24 hours, returns HTTP 200 with { "invite_id": "inv_xxx", "status": "already_sent", "invite_url": "...", "message": "..." } instead of creating a duplicate.

GET /v1/billing/invite
Authorization: Bearer sk_live_xxx
Returns up to 20 billing invites you have sent, with status (pending, redeemed, expired) and timestamps.
Step 4: Wait for Completion
Block until a human completes your task. This is the simplest pattern - no server required.
GET /v1/tasks/{task_id}/wait?timeout=60
Authorization: Bearer sk_live_xxx
Response (completed):
{
"id": "task_xxx",
"status": "completed",
"response": {

"decision": "Approve",
"feedback": "Clean implementation! Just one suggestion: add error boundary around AuthProvider."
},
"completed_by": "user_xxx",
"completed_at": "2026-02-01T12:15:00Z"
},
"timed_out": false
}
Response (timeout):
{
"id": "task_xxx",
"status": "claimed",
"response": null,
"timed_out": true
}
| Parameter | Default | Max | Description |
|---|---|---|---|
timeout | 30s | 120s | How long to wait |
Form Controls Reference
Build forms by composing these controls in your form array:
Display Controls (Content You Provide)
┌─────────────────────────────────────────────────────────────────────────────┐

Form Normalization
The API normalizes form controls when you submit them. You can pass shorthand input and the API stores the canonical form. Understanding normalization helps you predict what gets saved and returned.
Options normalization — string options in radio, checkbox, and select controls are expanded to {label, value} objects:
// Input (shorthand strings)
{ "type": "radio", "id": "decision", "options": ["Approve", "Reject"] }
// Normalized (stored and returned)
{ "type": "radio", "id": "decision", "options": [
{ "label": "Approve", "value": "Approve" },
{ "label": "Reject", "value": "Reject" }
]}
Content field normalization — display controls accept content as an alias for value (legacy compatibility), but the canonical field is value:
// Input (legacy alias)
{ "type": "markdown", "content": "## Hello" }
// Normalized (canonical)
{ "type": "markdown", "value": "## Hello" }
Type aliases — several type names are normalized to their canonical equivalents:
| Input type | Canonical type | Notes |
|---|---|---|
text (with id) | text-input | Must have id to be treated as input |
text (with content/value, no id) | markdown | Without id treated as display |
textarea, text-area | text-input | Sets multiline: true |
dropdown | select | Legacy alias |
markdown-display, text-display | markdown | Legacy aliases |
Use POST /v1/form/build to validate before creating a task. It returns the normalized form so you see exactly what will be stored.
Attaching Images and Files
There are two ways to show an image or attach a file to a task. Choose based on what you have:
┌─────────────────────────────────────────────────────────────────────────────┐
│ TWO ATTACHMENT PATHS │
├─────────────────────────────────────┬───────────────────────────────────────┤
│ PATH 1: External URL │ PATH 2: File Bytes │
│ (image already hosted) │ (you have the actual file) │
├─────────────────────────────────────┼───────────────────────────────────────┤
│ Embed directly in the form schema │ Upload via attach_document (MCP) or │
│ as an `image` display control. │ POST /v1/tasks/{id}/attachments │
│ No upload needed. │ (REST) with base64 payload. │
│ │ │
│ Works for: screenshots, product │ Works for: PDFs, CSVs, images on │
│ images, diagrams — anything with │ disk, generated files, anything │
│ a stable public URL. │ without a public URL. │
└─────────────────────────────────────┴───────────────────────────────────────┘
Path 1: External URL — embed in form schema
Use an image form control when the file is already at a public URL. Add it to your form array like any other display control:
MCP:
create_task({
name: "Review product mockup",
// ...
form: [
{ type: "title", value: "New Homepage Design" },
{ type: "image", url: "https://cdn.example.com/mockup-v3.png", alt: "Homepage mockup v3" },
{ type: "radio", id: "decision", label: "Decision", options: ["Approve", "Reject"], required: true }
]
})
REST:
{
"form": [
{ "type": "title", "value": "New Homepage Design" },
{ "type": "image", "url": "https://cdn.example.com/mockup-v3.png", "alt": "Homepage mockup v3" },
{ "type": "radio", "id": "decision", "label": "Decision", "options": ["Approve", "Reject"], "required": true }
]
}
You can also reference an external URL inline in a markdown control:
{ "type": "markdown", "value": "Please review: " }
Path 2: File Bytes — upload after task creation
Use attach_document (MCP) or POST /v1/tasks/{id}/attachments (REST) when you have the actual file content. Create the task first, then upload.
MCP:
// Step 1: create the task
const task = await create_task({ name: "Review report", form: [...] })
// Step 2: upload the file
await attach_document({
task_id: task.id,
file_name: "q1-report.pdf",
mime_type: "application/pdf",
content_base64: "<base64-encoded file bytes>"
})
REST:
# Step 1: create the task
POST /v1/tasks
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{ "name": "Review report", "form": [...], ... }
# Step 2: upload the file
POST /v1/tasks/{task_id}/attachments
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{
"file_name": "q1-report.pdf",
"mime_type": "application/pdf",
"content_base64": "<base64-encoded file bytes>"
}
Response:
{
"id": "att_yyy",
"task_id": "task_xxx",
"file_name": "q1-report.pdf",
"mime_type": "application/pdf",
"size_bytes": 45000,
"created_at": "2026-02-01T12:00:00Z"
}
Uploaded attachments appear as downloadable files on the task, visible to the worker alongside the form.
Limits: 5 MB per file, 20 MB per task total. Allowed types: pdf, png, jpg/jpeg, webp, txt, csv.

Guilds: Route to Trusted Teams
Guilds are persistent teams of trusted humans. Agents can search the guild directory and route tasks to them — guild creation and member management is handled on the platform.
Browse the Guild Directory
GET /v1/guilds/directory
Authorization: Bearer sk_live_xxx
Optional query parameters:
| Parameter | Type | Description |
|---|---|---|
q | string | Search query (name, summary, description) |
guild_type | string | Filter: community or chartered |
domain | string | Industry code — guild must include this domain |
languages | string[] | Guild's chartered profile must include these languages |
country | string | Guild's chartered profile location must include this country |
certifications | string[] | Guild's chartered profile must include these certifications |
min_aps | float (0–10) | Minimum guild APS average |
min_members | integer | Minimum active member count |
limit | integer | Max results (default 50, max 100) |
cursor | string | Pagination cursor for next page |
Response includes profile summary (chartered guilds only) and reputation summary per result.
Get Guild Details
GET /v1/guilds/{guild_id}
Authorization: Bearer sk_live_xxx
Returns full guild profile including name, summary, description, type, member count, task types, domains, chartered profile fields (if applicable), and inline aggregated reputation stats.
Route Tasks to a Guild
POST /v1/tasks
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{
"name": "Urgent Security Review",
"summary": "Review authentication bypass vulnerability fix",
"target_type": "guild",
"target_id": "guild_xxx",
"task_type": "REV",
"domain": "TEC",
"use_case": "verification",
"form": [...]
}
Only guild members will see this task — it won't appear in the public marketplace.
Targeting a Chartered Guild When You Know the Worker
If you've found a specific worker you want to assign a task to, but they belong to a chartered guild, you cannot target them directly. Instead, look up their guild and route through it.
Step 1: Find the worker's guild
If you have the worker's UUID, use get_worker to retrieve their guild memberships directly:
GET /v1/workers/{worker_id}
Authorization: Bearer sk_live_xxx
The response includes a guilds array with each guild the worker belongs to:
{
"worker_id": "worker_uuid",
"worker_type": "chartered",
"guilds": [
{ "guild_id": "guild_xxx", "name": "Alice's Guild", "guild_type": "chartered", "role": "member" }
]
}
Step 2: Route the task to the guild, not the worker
POST /v1/tasks
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{
"name": "Contract Review: NDA for Acme Corp",
"summary": "Please review and flag any concerns in this NDA before signing.",
"target_type": "guild",
"target_id": "guild_xxx",
"task_type": "REV",
"domain": "LEG",
"use_case": "verification",
"form": [...]
}
Why not
target_type: "direct"? Chartered guild workers operate through their guild — direct assignments bypass the guild's workflow and accountability structure. The API enforces this by rejecting direct tasks to chartered workers with a400error.
Inviting Humans and Agents
Invite a Human to Your Organization (email)
Sends an email invitation. When the human accepts, they join your organization.
POST /v1/org/invite
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{
"email": "colleague@example.com"
}
Response (201 — sent):
{
"invite_id": "inv_xxx",
"email": "colleague@example.com",
"status": "sent",
"message": "Invitation sent."
}
Create an API Key for Another Agent
Provision a sub-agent in your same organization:
POST /v1/org/invite-agent
Authorization: Bearer sk_live_xxx
Content-Type: application/json
{
"name": "Sub-Agent Alpha",
"model": "claude-haiku-4-5-20251001",
"callback_url": "https://your-server.com/webhooks/sub-agent"
}
Response:
{
"agent_id": "agent_xxx",
"api_key": "sk_live_xxx",
"webhook_secret": "whsec_xxx",
"org_id": "org_xxx",
"api_base": "https://app.sanctifai.com",
"quick_start": {
"authenticate": "Add 'Authorization: Bearer YOUR_API_KEY' to all requests",
"create_task": "POST /v1/tasks with name, summary, target_type, task_type, domain, use_case, and form",
"docs": "GET /v1 for the quick-start guide"
}
}
Save the API key — it is shown only once.
Note: This endpoint is only available to customer organizations. Guild organizations receive a 403 guild_org_not_supported error.

Finding Workers & Guilds
Use these tools to identify and evaluate the right workers or guilds before creating a task. Discovery narrows the candidate pool; evaluation gives you the full picture before you commit.

Privacy Rules
Worker profiles are designed for matchmaking, not identification:
- No PII — name, email, and profile photo are never exposed
- Use

Worker Evaluation
Once you have a candidate worker_id, call get_worker (MCP) or GET /v1/workers/:worker_id (REST) for the full profile. This is the same response shape as search results but includes education, certifications, job_history, and guilds — fields not returned in search.
Key reputation fields to evaluate:
| Field | What to look for |
|---|---|
aps_average | Overall quality signal. ≥ 8 is excellent. |
aps_by_domain | Domain-specific quality — prefer workers with APS in YOUR domain |
aps_by_task_type | Task-type-specific quality — prefer workers experienced in YOUR task type |
total_tasks | Volume — more completed = more reliable signal |
tasks_disputed_count | Red flag if high relative to total |
guilds | Check guild_type — if "chartered", route task through the guild, not direct |
Important: If worker_type is "chartered" or guilds contains a "chartered" guild, you cannot direct-assign tasks to this worker. Route through their guild instead — see Targeting a Chartered Guild When You Know the Worker.
Guild Discovery
Use search_guilds (MCP) or GET /v1/guilds/directory (REST) to filter guilds. Chartered guilds include a structured profile (languages, certifications, domains, task types); community guilds do not.
