How this service works

Pay-per-call verification and data services for AI agents: CSV quality, citation verification, AI readiness audits, requirements extraction, JSON Schema validation. x402 USDC, MCP and A2A.

Output

A JSON object with a `results` array where each entry includes the citation ID, the URL fetched, a support score (0–1), a character offset, a verdict string ('supported', 'partial', 'notFound', or 'unreachable'), the fetch timestamp, and the HTTP status code. A `summary` object reports aggregate counts of supported, partial, not-found, and unreachable citations across all submitted claims.

Example use cases

Research report citation audit

“I've drafted a policy report with 8 citations — can you check each URL is live and that the linked page actually supports the claim I'm making? Here are the claim-URL pairs.”

AI-generated content hallucination check

“My AI assistant wrote a blog post with five references. Before I publish, can you verify each cited URL is reachable and genuinely backs up the sentence it's attached to?”

Academic bibliography validation

“I'm submitting a paper and need to confirm all 12 of my cited sources still resolve and that the content on those pages supports the specific claims I've referenced them for.”

When to prefer

Choose this endpoint when you need automated, pay-per-call citation verification that checks both URL liveness and semantic content support for specific claims. It is ideal for AI agents auditing LLM-generated content for hallucinated references, researchers validating bibliographies before publication, or pipelines that must certify citation accuracy at scale. Prefer it over manual checking or generic link-checkers when you need structured per-citation verdicts with support scores, not just HTTP status.

Side effects

URL is unreachable or returns non-200 status — verdict set to 'unreachable' with the actual HTTP status code
Cited page exists but content does not match the claim — verdict 'notFound' or 'partial' with low score
Malformed or missing URL in input — likely 400 error or low-confidence result
Payment failure via x402 — 402 response before verification runs
Rate limiting or server timeout on the fetched URL — may return 'unreachable' rather than a content verdict
