## Tools (5)

- `check_usage`: Report how many verifications remain on this account for the current period.
- `estimate_claims`: 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.
- `recall_claim`: Look up whether a claim has already been verified on this account, without spending a verification.
- `top_up`: 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.
- `verify_claims`: 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.
