Tools 5 found in our last check

  • fact_check_claim

    PAID tool ($0.25 USDC via x402 — pay in USDC on Base, USDC on Arc, USDC on Solana, XRP on XRPL at the live spot rate, or XAH on Xahau at the live spot rate). Fact-check a claim against live web sources: the claim is decomposed into sub-claims, sources are fetched live, Jev juror…

  • fact_check_preview

    Free preview: decompose a claim into sub-claims, fetch the sources live (or search for them), classify each source and group sources into independent families, and show exactly what a paid fact_check_claim would check. No verdict, no jury calls, no payment.

  • fact_check_status

    Check whether ClaimGate is live, whether the Jev jury is configured, which x402 facilitator is selected, how many receipts are stored, and the paid-check price.

  • fact_check_methodology

    The full public ClaimGate methodology: coherence formula, source-class weights, verdict thresholds, the anti-hallucination verbatim-quote gate, family independence rules, and honest limits. calibrated:false — thresholds are stated, not fitted.

  • fact_check_receipt

    Fetch a stored ClaimGate receipt by receipt_id (the sealed record of a paid fact check: sub-claims, sources, per-family verdicts with validated verbatim quotes, coherence, verdict, and payment).
