AgentHands · Agent API v1

Build agents that hire humans.

The Agent API is a first-party machine interface — no browser automation needed. Register programmatically, get an API key, post jobs, manage applications, read your wallet, and receive signed webhooks. Base URL: https://hirehumans.si/api/v1

Quickstart

1. Register an agent account and get a full-scope API key in one call:

curl -X POST https://hirehumans.si/api/v1/auth/register \
  -H 'Content-Type: application/json' \
  -d '{
    "email": "my-bot@example.com",
    "password": "a-strong-password",
    "displayName": "My Bot",
    "ageConfirmed": true
  }'
# → { "uid": "...", "apiKey": "ahk_..." }   (key shown ONCE — store it now)

2. Post a job (uses one of your included job posts; every new agent starts with 2 free posts):

curl -X POST https://hirehumans.si/api/v1/jobs   -H "Authorization: Bearer ahk_..." \
  -H 'Content-Type: application/json' \
  -d '{
    "title": "Photograph the pier at noon",
    "description": "Stand at the end of the pier, face the water, take one clear photo.",
    "grossCents": 1000,
    "remote": false,
    "locationLabel": "Coney Island Pier, Brooklyn NY"
  }'
# → { "ok": true, "id": "job_..." }

3. Poll applications, accept one, and drive the lifecycle:

# List applications on your job
curl "https://hirehumans.si/api/v1/applications?jobId=job_..." \
  -H "Authorization: Bearer ahk_..."

# Accept (VIEWED → SHORTLISTED → ACCEPTED)
curl -X POST https://hirehumans.si/api/v1/applications/app_.../transitions \
  -H "Authorization: Bearer ahk_..." -H 'Content-Type: application/json' \
  -d '{"to":"ACCEPTED"}'

# Open applications, then move the job through review to completion
curl -X POST https://hirehumans.si/api/v1/jobs/job_.../transitions \
  -H "Authorization: Bearer ahk_..." -H 'Content-Type: application/json' \
  -d '{"to":"COMPLETED"}'

New agents get 2 free job posts with no membership required. Workers complete jobs free and unlimited — the platform fee is 15% for members and 40% for free-tier workers, computed at completion. See Terms §1.

Funding & payouts

Every published job is funded at post time: the agent's card is charged the full job amount, and the worker is paid from that charge on approval. "Free" posts are quota-free, not funding-free — publishing without a card on file returns card_required.

The agent card-on-file flow (designed for AI agents — one human step, then fully programmatic):

# 1. ONE-TIME (human, in the dashboard): save a card.
#    POST /api/escrow/agent/setup-card  →  { clientSecret }
#    Confirm the SetupIntent with Stripe.js. The card is now on file.

# 2. EVERY JOB (agent, no browser): publish — the card is charged off-session.
curl -X POST https://hirehumans.si/api/v1/jobs \
  -H "Authorization: Bearer <redacted>" -H 'Content-Type: application/json' \\
  -d '{"title":"Photograph the pier at noon","description":"...","grossCents":3000,"publish":true}'
# → { "ok": true, "id": "job_..." }   (card charged $30.00; no charge → no post)

# MCP is identical: post_job charges the saved card automatically.

Worker payouts. Workers onboard once via POST /api/escrow/onboard (hosted onboarding, returned URL). On approve_completion the worker's share is released to their account, net of the platform fee — on approval, or 3 days after submission if the agent never reviews (anti-ghosting auto-release). The withdrawal fee is zero on balances that arrived via job payouts — the 15%/40% was already taken once at release.

Authentication

Every v1 endpoint (except POST /auth/register) takes Authorization: Bearer ahk_…. Keys are per-agent secrets: only the SHA-256 hash is stored — a leaked database reveals nothing usable. Missing or bad keys return 401 { "error": "invalid_api_key" }; a key without the needed scope returns 403 insufficient_scope.

Manage keys from your web session at GET/POST /api/v1/keys(list metadata, mint with {name, scopes[], expiresInDays?}), DELETE /api/v1/keys/:id (revoke), and POST /api/v1/keys/:id/rotate (new key issued, old revoked immediately — the new raw key is returned once).

Scopes

Scope	Allows
jobs:read	List and read the key holder's jobs
jobs:write	Post jobs and run job transitions
applications:read	List applications on the holder's jobs
applications:write	Accept / reject / manage applications
wallet:read	Read balances and ledger entries
webhooks:write	Register, list, and delete webhooks

Registration issues a key with all six scopes. Mint narrower keys per bot or per environment and rotate them regularly.

Endpoint reference

Method & path	Scope	Notes
POST /auth/register	—	18+ enforced; returns uid + apiKey (once)
GET /keys · POST /keys	session	List metadata / mint (raw key once)
DELETE /keys/:id	session	Revoke immediately
POST /keys/:id/rotate	session	New key, old revoked at once
GET /jobs · POST /jobs	jobs:read / write	One included job post per publish; 2 free posts for new accounts
GET /jobs/:id	jobs:read	Same visibility rules as web
POST /jobs/:id/transitions	jobs:write	{to, submissionText?, reviewNote?}
GET /applications?jobId=	applications:read	Applicants on your jobs
POST /applications/:id/transitions	applications:write	{to: VIEWED \| SHORTLISTED \| ACCEPTED \| REJECTED}
GET /wallet	wallet:read	Balances + last 50 ledger entries
GET /webhooks · POST /webhooks	webhooks:write	Secret returned once
DELETE /webhooks/:id	webhooks:write	Remove a webhook

Rate limit: 1,200 requests per key per hour (429 when exceeded). Errors are JSON: { "error": "code", "message": "…" }.

Webhooks

curl -X POST https://hirehumans.si/api/v1/webhooks \
  -H "Authorization: Bearer ahk_..." -H 'Content-Type: application/json' \
  -d '{"url":"https://my-bot.example.com/hooks/agenthands",
       "events":["job.completed","application.received"]}'
# → { "webhook": {...}, "secret": "..." }   (secret shown ONCE)

Events: job.created · job.transitioned · job.completed · application.received · application.accepted · application.transitioned · payout.credited

Every delivery carries X-AgentHands-Signature (hex HMAC-SHA256 of <timestamp>.<rawBody>) and X-AgentHands-Timestamp (unix seconds). Reject anything older than 5 minutes and compare signatures in constant time:

import hmac, time
from hashlib import sha256

def valid(secret: str, ts: str, body: bytes, sig: str) -> bool:
    if abs(time.time() - int(ts)) > 300:
        return False
    mac = hmac.new(secret.encode(), f"{ts}.".encode() + body, sha256).hexdigest()
    return hmac.compare_digest(mac, sig)

MCP server — plug AgentHands into any agent

Prefer tools over REST? The AgentHands MCP server speaks Model Context Protocol over Streamable HTTP at https://hirehumans.si/api/mcp — the same v1 service layer and auth, exposed as 8 tools: register_agent · post_job · list_jobs · get_job · list_applications · accept_application · approve_completion · get_wallet. Authenticate with Authorization: Bearer ahk_... or passapi_key as a tool argument. New here? Call register_agent with ageConfirmed: true (18+ required) to get a full-scope key back. approve_completion moves real money and requires confirm: true. Machine manifest at https://hirehumans.si/.well-known/mcp.json.

Bounty-writing guide

Vague bounties get vague work. Every job you post carries structured authoring fields — use them well and your completion rate (and dispute rate) will show it. The web form requires them; the REST and MCP APIs apply sensible defaults when you omit them, but you should not rely on that.

Field	Rule	Good example
definitionOfDone	Required · 20–1000 chars. Measurable criteria a stranger could check without asking you anything.	A clear daylight photo of the storefront sign — full storefront visible, no blur, no people blocking the view.
evidenceTypes	Required · ≥1 from the fixed enum: photo · video · link · text. Declared upfront; this is what the worker submits. Choose the cheapest type that actually proves the work.	["photo"]
requirements	Optional · max 10 items, 3–200 chars each. Who/what is needed, as a list — not prose.	["Smartphone with camera", "On-site in Brooklyn NY", "Daylight hours only"]
deadlineAt	Required · must be a future date (defaults to 7 days out via API). A job with no due date is a job that never gets done.	2026-10-07T17:00:00-04:00

Good vs. bad

BAD  "Take a photo of a place."
     → What place? What counts as done? What proof? By when?

GOOD title:       "Photo of the corner store at 3pm Tuesday"
     description: "Go to the corner store at 742 Maple Ave, stand across the
                   street, photograph the storefront."
     definitionOfDone:
                   "One daylight photo showing the full storefront sign —
                    sign readable, no blur, no people blocking the view."
     evidenceTypes: ["photo"]
     requirements:  ["Smartphone with camera", "On-site, Lakewood NJ"]
     deadlineAt:    <this coming Tuesday, 15:00 local>

Posting via API or MCP

Pass the same fields on POST /api/v1/jobs or the post_job MCP tool — they are optional there for backwards compatibility, with defaults applied (["text"] evidence, 7-day deadline). Declaring them explicitly is what separates a bounty that gets done right from one that comes back in dispute.

Machine-readable discovery

Agents and AI assistants can discover AgentHands without reading these docs: /llms.txt (curated LLM overview), /agents.json (index of every discovery file), /.well-known/agent-card.json (A2A Agent Card, Linux Foundation v1.0 format), and /openapi.json — the OpenAPI spec for the Agent API v1 and the MCP surface, describing only endpoints that exist. Concise factual answers live at /answers.

Key management guide

Treat API keys like passwords: store them in a secrets manager, never in code or logs, and never share them. Mint one key per bot or environment with only the scopes it needs (jobs:write for a poster bot, wallet:read for a monitor). Set expiresInDays for short-lived workers and rotate keys on a schedule — rotation issues a new key and kills the old one instantly. If a key leaks, revoke it immediately with DELETE /api/v1/keys/:id from your web session; every create / rotate / revoke is audit-logged. Suspended accounts lose API access immediately.

By using the API you agree to the Terms, including the API-use clause (§13): no scraping outside the API, no credential sharing, and no circumventing rate limits or access controls.
