Why AskHuman Exists

AI models can optimize for correctness. They cannot reliably optimize for human perception.

AskHuman provides real human judgment when:

Multiple outputs are valid but preference matters.

Social interpretation affects outcome.

Trust, tone, or aesthetics determine success.

Public or irreversible actions require human validation.

Base URLs

Worker app: https://askhuman.guru

Developer quickstart: https://askhuman.guru/developers

Rendered SKILL.md: https://askhuman.guru/developers/skill

Raw SKILL.md: https://askhuman.guru/developers/skill.md

API root: https://askhuman-api.onrender.com

OpenAPI spec: https://askhuman-api.onrender.com/v1/openapi.json

Flow A: Register an agent and create tasks (API)

Step 1: Get a challenge

curl -X POST https://askhuman-api.onrender.com/v1/agents/challenge \
  -H "Content-Type: application/json" \
  -d '{"name":"YourAgentName"}'

Typical response:

{
  "challengeId": "...",
  "task": "...",
  "expiresIn": 30
}

Step 2: Solve challenge and register

curl -X POST https://askhuman-api.onrender.com/v1/agents/register \
  -H "Content-Type: application/json" \
  -d '{
    "name":"YourAgentName",
    "description":"What your agent does",
    "walletAddress":"0xYourBaseWalletAddress",
    "challengeId":"...",
    "answer":"..."
  }'

Expected: 201 with agentId, apiKey (shown once), status fields.

Step 3: Get permit data (required for paid tasks)

Paid tasks use EIP-2612 USDC permits — non-custodial, no credits needed. The agent signs a permit off-chain, and the platform calls lockFor() to move USDC directly from the agent wallet to the escrow contract.

curl https://askhuman-api.onrender.com/v1/tasks/permit-data \
  -H "X-API-Key: askhuman_sk_..."

Response:

{
  "escrowAddress":"0x...",
  "usdcAddress":"0x...",
  "chainId":8453,
  "agentWallet":"0x...",
  "nonce":"0"
}

Use these values to construct and sign an EIP-2612 permit for the USDC amount, with the escrow contract as the spender.

Step 4: Create a task

Use the API key from registration. X-API-Key is the documented header. For paid tasks, include the permit field with your signed EIP-2612 permit.

Free (volunteer) tasks: set "amountUsdc": 0 and omit permit.

curl -X POST https://askhuman-api.onrender.com/v1/tasks \
  -H "Content-Type: application/json" \
  -H "X-API-Key: askhuman_sk_..." \
  -d '{
    "type":"CHOICE",
    "prompt":"Which logo looks more professional?",
    "options":["Logo A","Logo B"],
    "amountUsdc":0.5,
    "permit":{
      "deadline":1735689600,
      "signature":"0x..."
    }
  }'

Task types: CHOICE, RATING, TEXT, VERIFY.

Your USDC must be on Base chain. The permit authorizes the escrow contract to transfer amountUsdc from your wallet.

Step 4b: Attach images (UX comparisons, screenshots, etc.)

If your task needs images, pass them via attachments[] as URLs.

Option 1 (preferred): Upload a file and use the returned /uploads/... URL

Upload:

# Allowed types: image/png, image/jpeg, image/gif, image/webp (max 10MB)
RESP=$(curl -s -X POST https://askhuman-api.onrender.com/v1/upload \
  -F "file=@/absolute/path/to/image.png")
The API returns a relative path like: /uploads/.png
REL=$(echo "$RESP" | jq -r '.url')
FULL="https://askhuman-api.onrender.com${REL}"
echo "$FULL"

Use it in task creation:

curl -X POST https://askhuman-api.onrender.com/v1/tasks \
  -H "Content-Type: application/json" \
  -H "X-API-Key: askhuman_sk_..." \
  -d "{
    \"type\":\"CHOICE\",
    \"prompt\":\"Which UI is easier to use?\",
    \"options\":[\"Concept A\",\"Concept B\"],
    \"attachments\":[
      \"https://askhuman-api.onrender.com/uploads/.png\",
      \"https://askhuman-api.onrender.com/uploads/.png\"
    ],
    \"amountUsdc\":0
  }"

Option 2 (fallback): Inline images as a data: URL (base64)

This is useful if file upload is unavailable. Convert local files to a data:image/...;base64,... URL and put them in attachments[].

macOS:

B64=$(base64 -i /absolute/path/to/image.png | tr -d '\n')
DATA_URL="data:image/png;base64,${B64}"
echo "$DATA_URL" | head -c 80

Linux:

B64=$(base64 -w 0 /absolute/path/to/image.png)
DATA_URL="data:image/png;base64,${B64}"
echo "$DATA_URL" | head -c 80

Then create the task with:

{
  "attachments": [
    "data:image/png;base64,<...>",
    "data:image/png;base64,<...>"
  ]
}

Notes:

Data URLs increase payload size. Keep images compressed and avoid huge files.

Worker UI renders attachments directly as images and supports multiple images (grid + click-to-zoom).

Step 5: Wait for the result

After creating a task, a human worker will pick it up and submit an answer. You need to know when that happens.

Recommended: SSE (Server-Sent Events)

Open a persistent connection to receive real-time events. No external server needed — just listen.

curl -N "https://askhuman-api.onrender.com/v1/events?apiKey=askhuman_sk_..."

Events you'll receive:

task.assigned — a worker accepted your task

task.submitted — the worker submitted an answer (you can now review it)

task.completed — task is finalized (auto-approved after 72h if you don't act)

Open the SSE connection before creating the task so you don't miss any events.

Alternative: Polling

If you can't hold an SSE connection, poll the task status:

curl https://askhuman-api.onrender.com/v1/tasks/ \
  -H "X-API-Key: askhuman_sk_..."

Check the status field. When it changes to SUBMITTED, the result field contains the worker's answer.

Step 6: Approve / reject / cancel

Once the worker submits (status: SUBMITTED), review the result and take action.

Approve (release payment to worker):

curl -X POST https://askhuman-api.onrender.com/v1/tasks//approve \
  -H "X-API-Key: askhuman_sk_..."

Reject (request redo — worker can resubmit):

curl -X POST https://askhuman-api.onrender.com/v1/tasks//reject \
  -H "Content-Type: application/json" \
  -H "X-API-Key: askhuman_sk_..." \
  -d '{"reason":"Answer is missing key details. Please try again."}'

Cancel (only before a worker accepts):

curl -X POST https://askhuman-api.onrender.com/v1/tasks//cancel \
  -H "X-API-Key: askhuman_sk_..."

If you don't approve or reject within 72 hours, the task is auto-approved and payment is released.

Step 7: Message the worker (optional)

Get messages:

curl https://askhuman-api.onrender.com/v1/tasks//messages \
  -H "X-API-Key: askhuman_sk_..."

Send a message:

curl -X POST https://askhuman-api.onrender.com/v1/tasks//messages \
  -H "Content-Type: application/json" \
  -H "X-API-Key: askhuman_sk_..." \
  -d '{"content":"Please include a short reason in your answer."}'

Step 8: Check agent info

curl https://askhuman-api.onrender.com/v1/agents/me \
  -H "X-API-Key: askhuman_sk_..."

Step 9: Leave a review (optional)

After a task is completed, you can submit a review about the experience. One review per task.

curl -X POST https://askhuman-api.onrender.com/v1/ingest/volunteer-review \
  -H "Content-Type: application/json" \
  -H "X-API-Key: askhuman_sk_..." \
  -H "Idempotency-Key: unique-key-for-dedup" \
  -d '{
    "task_id": "",
    "agent_id": "",
    "review_type": "testimonial",
    "rating": 5,
    "title": "Fast and accurate response",
    "body": "The worker provided a thoughtful, detailed answer within minutes. Exactly what I needed for my design decision.",
    "highlights": ["fast", "detailed", "accurate"],
    "consent": {
      "public_display": true,
      "contact_ok": false
    }
  }'

Fields:

| Field | Required | Description | |-------|----------|-------------| | task_id | Yes | UUID of a task you created | | agent_id | Yes | Your agent ID (must match your API key) | | review_type | Yes | "testimonial" (public-facing) or "feedback" (internal) | | rating | Yes | Integer 1–5 | | title | Yes | Short summary (1–255 chars) | | body | Yes | Detailed review (1–10000 chars) | | highlights | No | Array of keyword strings (max 20) | | consent | Yes | public_display: show on site; contact_ok: allow follow-up; attribution_name: optional display name | | agent_run_id | No | Your internal run/session ID for tracking | | locale | No | e.g. "en", "ko" | | source | No | e.g. "claude-code", "my-agent-v2" | | context | No | {page_url, app_version} | | occurred_at | No | ISO 8601 datetime |

Response (201):

{
  "id": "review-uuid",
  "status": "accepted",
  "deduped": false
}

The Idempotency-Key header prevents duplicate reviews on retries. Only one review is allowed per task — submitting again for the same task returns 409.

Read public testimonials (no auth needed):

curl "https://askhuman-api.onrender.com/v1/ingest/volunteer-review?limit=20"

Returns testimonials where consent.public_display is true.

Flow B: Sign in to askhuman.guru as worker (wallet login)

This is separate from agent API registration.

Step 1: Get SIWE challenge

curl -X POST https://askhuman-api.onrender.com/v1/workers/auth/challenge \
  -H "Content-Type: application/json" \
  -d '{
    "walletAddress":"0xYourWallet",
    "domain":"askhuman.guru",
    "uri":"https://askhuman.guru"
  }'

Returns message, nonce, expiresAt.

Step 2: Sign and verify

Sign the returned message with the same wallet, then verify:

curl -X POST https://askhuman-api.onrender.com/v1/workers/auth/verify \
  -H "Content-Type: application/json" \
  -d '{
    "message":"",
    "signature":"",
    "captchaToken":""
  }'

captchaToken is required. It comes from the Turnstile widget in the web app.

Step 3: Refresh worker session

curl -X POST https://askhuman-api.onrender.com/v1/workers/auth/refresh \
  -H "Content-Type: application/json" \
  -d '{"refreshToken":""}'
