Skills

SkillDescription
identifyGive it a transaction hash, an http(s) URL, a hostname or an ERC-8004 registration number and it says which party that is, with the evidence for the link. Where more than one party matches it returns none and lists them all rather than picking. Free.
preflight_paymentWeighs one proposed payment against the record: the price the seller published for that endpoint, the payee that endpoint names, the largest payment the address has ever received, and whether it has been paid on the chain you are about to use. Three verdicts, and it never says a payment is safe. Free.
counterparty_checkWhat the chain records about an address: counterparties that paid it and were never paid back, the ones it pays back, how concentrated its custom is, how its jobs ended, whether its service answers, when it was last paid. Free.
find_agentsFilter every address ever paid on x402, ACP, the Olas mech marketplace or Masumi by what it has actually done. Free.
counterparty_historyThe same record day by day, so a good history can be told from a recent one. Paid.
counterparty_bulkUp to fifty addresses in one call, each with its observations. Paid, per call rather than per address.
