• GET /v1/watch/addresses — Has anything changed about counterparties you already screened? Re-checks a list of addresses against OFAC designations and delistings since a timestamp you supply, so a verdict you acted on last month does not go quietly stale. Stateless: no watchlist is stored and nothing is sent to you — pass the returned checkedAt back as `since`. Free alternative: GET /v1/watch. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.002007 USDC on Base)
• GET /v1/watch/feed — Has the sanctions feed moved since you last looked? Every OFAC designation and delisting since a timestamp you supply, with no address list to send — match the feed against your own counterparty book locally, so the service never learns which addresses are yours. The trivial cron: poll this, pass the returned checkedAt back as `since`. Free alternative: GET /v1/watch. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.002003 USDC on Base)
• GET /v1/registry/agents — The filtered ERC-8004 directory: which registered agents are actually alive, and which accept x402. Around a third of registrations on Base carry a compliant file and a declared service, and one in twelve of those declares x402 — this returns them, rather than screening eighty thousand addresses one at a time. GET /v1/registry publishes the split, free. 100 agents per page. Free alternative: GET /v1/registry. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.010001 USDC on Base)
• POST /v1/verify/batch — Screen up to 10 addresses in one call: OFAC sanctions check, trust score, risk band and recommendation for each. For vetting a counterparty set before a run of payments, maintaining an allowlist, or auditing wallets you already pay. Free alternative: GET /v1/verify. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.010003 USDC on Base)
• GET /v1/provenance/chain — Where did this address get its money? Walks the funding chain upward and returns the account that ultimately paid for the wallet, plus a cluster id. Two addresses funded from the same account are not independent parties, however unremarkable each looks alone — the cheapest strong signal that an identity was manufactured. Works on any address, not only registered agents. Free alternative: GET /v1/provenance. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.010002 USDC on Base)
• GET /v1/verify/quick — Is this counterparty safe to pay or accept payment from? Screens it against the OFAC sanctions list, then SYBIL-FILTERS its ERC-8004 reputation: reviewers are clustered by funding source, one vote each, so feedback bought from one purse counts once. Returns an explainable 0-100 score, a proceed / hold / block recommendation, and insufficient_data rather than a guess. Free alternative: GET /v1/verify. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.002 USDC on Base)
• GET /v1/verify/deep — Should you approve this contract? Everything in quick, plus static analysis of the bytecode: privileged functions (mint, pause, blacklist, arbitrary withdrawal), proxy and upgradeability detection, dangerous opcodes, DeFi protocol classification and source-verification status. Free alternative: GET /v1/verify. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.01 USDC on Base)
• GET /v1/endpoint/screen — Is this x402 endpoint safe to pay? Reads its payment challenge under BOTH protocol versions — v1 body and v2 PAYMENT-REQUIRED header, so a v2-only service is not read as dead — then screens the payout wallet it advertises: OFAC sanctions, sybil-filtered ERC-8004 reputation, on-chain behaviour. Flags versions that name different recipients. Scores the wallet, not the service. Free alternative: GET /v1/endpoint. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.005 USDC on Base)
• GET /v1/search/agents — Which live agents can do X — and which of them are safe? Searches the skills, domains and names ERC-8004 agents declare, across the registrations this service sweeps continuously, and returns only the ones answering. Each row carries the endpoint to call, the wallet a payment reaches, and that wallet's risk band and sanctions verdict — one call instead of a screening per row. Free alternative: GET /v1/search. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial. (0.005001 USDC on Base)
• GET /v1/reputation — ERC-8004 agent reputation with sybil filtering: reviewers are clustered by who funded them and each cluster counts once, so reviewers paid for from one wallet count as one vote. Returns feedback and reviewer counts, independent clusters, the sybil-flagged share, counts by evidence class (payment proof, task link, none) and per-tag means, and refuses to average tags with conflicting scales. Base. Free: GET /v1/verify. Trial: /v1/trial. (0.002006 USDC on Base)
