    Description, as the server wrote it
    FREE. Break text into checkable claims and report how many there are and how many credits verifying them would cost. Spends nothing and verifies nothing. Always call this before verify_claims on anything longer than a sentence or two — an article can contain 20 claims, and each claim costs one credit, so the user should see the price before agreeing to it.

    Description, as the server wrote it
    Buy more verification credits without leaving the conversation. Call with confirm false (or omit it) to see the price, the card on file and the remaining monthly limit; call again with confirm true once the user has agreed. Charges the card the user already saved and authorised for in-chat top-ups — if no card is saved, or the bank requires the cardholder present, it returns a secure checkout link instead of charging.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Fact-check text against live web evidence from two independent retrievers, then have a model from a different lab audit the verdict. Returns per-claim verdicts: SUPPORTED, CONTRADICTED, UNSUPPORTED (searched and found nothing — not the same as false), or UNVERIFIABLE (opinion or prediction). Use before relying on a factual claim, or to check your own draft answer before sending it.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
