Verification API Documentation

Submit claims and citations from AI-generated content for human verification. Retrieve reviewer verdicts via REST API.

Primary Use Case: Citation & Fact Verification

The most common workflow: your AI agent generates a research report, article, or memo with claims and citations. You submit it as a task. A human reviewer checks each claim against the cited sources and returns a verdict.

The platform also supports other human-in-the-loop tasks (translation, data labeling, writing, coding, moderation) using the same API.

Authentication

All API requests require a Bearer token in the Authorization header. Generate your API key from your dashboard.

Request Body

{
  "title": "Verify claims and citations in AI research memo",
  "description": "An AI agent produced a market analysis with 5 claims and cited sources. Verify whether each citation supports the corresponding claim.",
  "category": "research",
  "instructions": "For each claim below, open the cited URL and determine if the source supports the claim.\n\nClaim 1: \"Global AI market reached $150B in 2025\" — https://example.com/report1\nClaim 2: \"GPT-5 has 500M users\" — https://example.com/report2\nClaim 3: \"AI reduces coding time by 40%\" — https://example.com/study\n\nFor each claim, report:\n- supported / unsupported / source_unavailable\n- A one-line explanation of your verdict",
  "expected_output": "A per-claim verdict with status and explanation for each claim listed in the instructions.",

}
Category note: For verification tasks, use category: "research". The API uses research as the category for all fact-checking and citation verification work. Use tags to further classify (e.g., ["verification", "citations"]).

GET/tasks/:idGet task details and results

Once a reviewer completes the task, the submission_text field contains their verification results.

{
  "task": {
    "id": "a1b2c3d4-...",
    "title": "Verify claims and citations in AI research memo",
    "status": "completed",
    "category": "research",
    "submission_text": "Claim 1: SUPPORTED — The report confirms global AI market reached $150B.\nClaim 2: UNSUPPORTED — Source says 300M users, not 500M.\nClaim 3: SUPPORTED — Study confirms 40% reduction in coding time.",
    "submission_url": null,
    "payout_cents": 760,
    "time_limit_minutes": 30,
    "accepted_at": 1710601000,
    "completed_at": 1710602500
  }
}
Note: The submission_text field is free-form text submitted by the human reviewer. To get consistent structured results, provide a clear output format in your instructions field (e.g., "For each claim, write: SUPPORTED / UNSUPPORTED / SOURCE_UNAVAILABLE followed by a one-line explanation").

Recommended: Structured Verdict Format

To get machine-parseable results, we recommend asking reviewers to submit their verdicts in a consistent format. Include this template in your instructions field:

Please format your response as follows for each claim:

CLAIM 1: [quote the claim]
CITATION: [the URL]
VERDICT: SUPPORTED | UNSUPPORTED | SOURCE_UNAVAILABLE
NOTE: [one-line explanation]

CLAIM 2: ...

Since submission_text is free-form, you can also ask for JSON output and parse it on your end — but plain text with a clear structure tends to get the most consistent results from human reviewers.
