Fact-check a whole answer: extracts every checkable claim and verifies each one against public Wikipedia sources, returning a verdict, confidence, quote and source URL per claim plus suggested next actions. Use it to audit chatbot or RAG output before showing it to a user. Price: $1.00 USDC on Base per call via x402; this MCP call returns payment instructions and the paid HTTP route POST /v1/check_answer returns the per-claim results. Read-only.

Fact-check a whole answer: extracts every checkable claim and verifies each against Wikipedia, plus Wikidata structured facts for dates, numbers, quantities, ordinals and records. Returns per-claim verdict, confidence, quote, source URL, sentence span and suggested_correction (quoted only from cited sources when contradicted/outdated), plus an answer-level summary with overall_verdict, counts and problem_sentences. Abstained rather than guessed. Use to audit chatbot or RAG output. Price: $1.00 USDC on Base per call via x402; this MCP call returns payment instructions and POST /v1/check_answer returns the results. Read-only.
2026-10-14extract_claimschangeddescription, output schema
before
Split a text (for example an AI-generated answer) into atomic factual claims, each with its character span and a grounding_required flag that says whether it is a checkable fact (questions, greetings and opinions are flagged false). Use it before verify_claim to decide what to check. Price: $0.05 USDC on Base per call via x402; this MCP call returns payment instructions and the paid HTTP route POST /v1/extract_claims returns the claims. Read-only, no side effects.
after · 52% of words in common
Split a text (for example an AI-generated answer) into atomic factual claims. Each claim includes span, grounding_required, claim_type (number|date|quantity|quote|named_entity_fact|comparison|opinion|prediction|other), check_worthiness (high|medium|low), and the source sentence. Hedges are stripped, pronouns are resolved across sentences, and compound sentences are split. Questions, greetings, opinions and predictions are marked grounding_required false. Use before verify_claim. Price: $0.05 USDC on Base per call via x402; this MCP call returns payment instructions and POST /v1/extract_claims returns the claims. Read-only.

Tools (4)

`check_answer`read-only	Fact-check a whole answer: extracts every checkable claim and verifies each against Wikipedia, plus Wikidata structured facts for dates, numbers, quantities, ordinals and records. Returns per-claim verdict, confidence, quote, source URL, sentence span and suggested_correction (quoted only from cited sources when contradicted/outdated), plus an answer-level summary with overall_verdict, counts and problem_sentences.

Price: $1.00 USDC on Base per call via x402; this MCP call returns payment instructions and POST /v1/check_answer returns the results. Read-only.
`deep_verify`read-only	Multi-source verification of up to three claims in a text against Wikipedia, Wikidata, Google News, Europe PMC (PubMed studies), FRED (US economic data) and SEC EDGAR (US company filings). Returns verdict, confidence, evidence for and against with quotes and URLs, and flags contradiction when sources disagree.

`extract_claims`read-only	Split a text (for example an AI-generated answer) into atomic factual claims. Each claim includes span, grounding_required, claim_type (number\|date\|quantity\|quote\|named_entity_fact\|comparison\|opinion\|prediction\|other), check_worthiness (high\|medium\|low), and the source sentence. Hedges are stripped, pronouns are resolved across sentences, and compound sentences are split. Questions, greetings, opinions and predictions are marked grounding_required false. Use before verify_claim. Price: $0.05 USDC on Base per call via x402; this MCP call returns payment instructions and POST /v1/extract_claims returns the claims. Read-only.
`verify_claim`read-only	Check one factual claim against public Wikipedia sources and return a verdict (supported, contradicted, outdated, mixed or insufficient_evidence), a confidence score, a short reason, the supporting quote and the source URL.
