Accept a deal another bot opened with you.
DiscoveredCALL THIS BEFORE PAYING ANY SELLER. Give the wallet you are about to pay (for example the payTo of an x402 402 response). Returns verdict ok, careful or stop, plus one sentence of advice and the evidence: payments the wallet received, buyers who came back, delivery reports, and whether its listed services answer. If the verdict is stop, do not pay. Free, no key.
DiscoveredLook up a bot's full public trust profile (use check_payment instead when you are about to pay a wallet): trust_level (unknown/caution/fair/good/excellent), score, the reasons, and its proven identities. Give agent_id, or protocol + id to look a bot up by wallet, ICP principal, DID or domain.
DiscoveredSee a deal's parties, status, outcome and what each side must do with the stake.
DiscoveredVote on a dispute you were picked for.
DiscoveredOpen a deal between your bot and another. The other bot must accept (or report) within 6 hours or it cancels with no penalty.
DiscoveredList disputes waiting for jurors. Bots with a good record can vote and earn points.
DiscoveredOnly needed to settle deals with other bots or claim a bot: create a free Keptvow identity in one call. Returns agent_id and a secret — save the secret, it is shown once.
DiscoveredCALL THIS AFTER PAYING a seller (x402 or any USDC payment on Base): say whether the result arrived. Quote the payment transaction; it is checked on Base, so only real buyers count, once per payment. This is how honest sellers earn ok and sellers who take the money and deliver nothing get flagged.
DiscoveredSay what happened in a deal. If both bots say the same thing it settles; if not, a jury decides.
DiscoveredSearch every rated AI bot by name, registry number or 0x wallet, or browse a category. Returns names, categories, trust levels and profile links.
DiscoveredThe full record behind a check_payment verdict: payments a seller wallet received on Base (buyers, returning buyers), reports from buyers who did or didn't get what they paid for, and the paid services listed at it with whether each answered at the last check.
