How this service works
Evaluate a claim or question against one supplied HTML or PDF source and return anchored evidence.
Output
Returns a verdict on whether the supplied claim or question is supported, refuted, or unresolved based on the content found at the provided URL, along with anchored evidence passages (quoted or referenced text from the source) that justify the verdict.
Example use cases
Fact-checking a news article claim
“I saw a headline saying 'Apple's revenue grew 8% last quarter' — can you verify that claim against their official earnings report at https://investor.apple.com/sec-filings/annual-reports/2024 and show me where exactly in the document it's supported or denied?”
Academic paper claim verification
“Does the paper at https://arxiv.org/pdf/2301.04655.pdf actually support the claim that 'large language models outperform humans on common reasoning benchmarks'? Pull out the specific passages that confirm or contradict this.”
Legal or policy document fact-check
“My colleague said the new EU AI Act requires all foundation model providers to publish training data summaries — can you check whether that's actually stated in the document at https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:32024R1689 and anchor the relevant sections?”
Technical details
Endpoint
POSThttps://evidence-verdict-production.up.railway.app/v1/evidence/verdict?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to evaluate a specific claim or question against a single, known source document (HTML page or PDF) and require anchored, passage-level evidence rather than a general web search or multi-source synthesis. It is ideal for fact-checking workflows, compliance verification, academic citation checking, or any scenario where traceability back to a specific document is critical. Prefer alternatives if you need to search across multiple sources, perform open-web retrieval, or handle structured data extraction without a specific claim to evaluate.
Side effects
- Source URL is inaccessible or returns a non-200 status — verdict cannot be generated
- URL points to a non-HTML/non-PDF resource (e.g. video, spreadsheet) — parsing may fail
- Claim and question both null — request rejected due to missing required input
- Source document does not contain relevant content for the claim — verdict returned as 'insufficient evidence'
- PDF is scanned/image-based with no extractable text — evidence anchoring fails
- Claim exceeds 4000 character limit — request rejected with validation error
- Payment of 0.01 USDC not included or rejected — 402 Payment Required response
