https://trust-agent.io/Who funded this wallet? Walks the funding chain upward from any address, up to 3 hops, and returns the first funder, each hop, the origin and a cluster id shared by every address paid for from the same account, the cheapest signal that two counterparties are one operator. Marks an origin that is infrastructure (a bridge, exchange or payout contract) and says when funding could not be traced. Ba...
Paid verification
How it worksNo sponsored paid call yet.
Pay this endpoint once from your own wallet (Base USDC, up to $1.00) and we call it and record what came back. Your wallet pays the listed recipient directly; Agent Tools never holds funds. Sponsored checks prove delivery; they do not count as demand.
Quality grade
How grading works- ✓ Answers a real HTTP 402 challenge
- ✓ Publishes a /.well-known/x402 descriptor
- ✓ Payment address on record
- ✓ Settlement network declared
- ✓ Price declared
x402 readiness
Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here A, 72.1/100), which weighs availability, payability and on-chain demand. How the two differ
| Valid payment requirements | 10/10 | Payment requirements carry a payee, a mainnet network and a price. |
| Live 402 challenge | 20/25 | Endpoint reachable; its 402 challenge was seen earlier (275 ms). |
| x402 version | n/a | x402 version not observed yet. |
| Signed descriptor | n/a | No x402 standard defines a signed descriptor. |
| Uptime (30 days) | 15/15 | 32/32 probes succeeded over 30 days (100%). |
| Resource declaration | 10/10 | Declares 11 paid resource(s). |
| Verified identity | 5/10 | Publisher descriptor (/.well-known/x402 or OpenAPI) on record; claim this listing to verify domain control. |
| Freshness + modern flags | 5/5 | seen in a source within 7 days; declares x402. |
| Security declaration | n/a | Payment is the access control for an x402 resource. |

https://trust-agent.io/v1/search/agents
Find AI agents by skill: searches what live ERC-8004 agents declare (skill, domain or name) and returns each match with its endpoint, payout wallet and that wallet's risk band and OFAC sanctions verdict, plus a funding cluster when two rows are one operator. Optionally only agents that accept x402.
https://trust-agent.io/v1/endpoint/screen
Is this x402 endpoint safe to pay? Reads its payment challenge (v1 body and v2 PAYMENT-REQUIRED header), lists every offer, then screens the payout wallet: OFAC SDN check, 0-100 trust score, risk band and proceed / hold / block with itemized flags. Flags offers that name different recipients. It sco
https://trust-agent.io/v1/verify/quick
Sanctions screening for a crypto wallet before you pay it: checks the address, and an agent's owner and payout wallet, against OFAC SDN-listed EVM addresses, then returns a 0-100 trust score, risk band and proceed / hold / block from on-chain history and sybil-filtered ERC-8004 reputation. Every fla
https://trust-agent.io/v1/verify/deep
Smart contract security check before you approve or pay an address: reads the bytecode, behind proxies too, for privileged functions (mint, pause, blacklist, upgrade), dangerous opcodes and protocol type, and checks whether a single key holds those powers. Adds OFAC SDN screening, who funded the add
https://trust-agent.io/v1/token/honeypot
Honeypot check for a Base token: can you sell it after you buy? Simulates a buy and a sell on its Uniswap v2, v3 or v4 or Aerodrome pool and returns sellable, high_tax, honeypot or unknown, both taxes and the pool, plus the owner powers in its code, proxies included (mint, blacklist, pause, fee chan
https://trust-agent.io/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 pro
https://trust-agent.io/v1/watch/addresses
Sanctions monitoring for wallets you already screened: send up to 50 addresses and a since timestamp, get every OFAC SDN designation or delisting that touched them since then, plus when the list was last synced and whether the change log reaches back that far. Stateless: nothing is stored or pushed;
https://trust-agent.io/v1/watch/feed
OFAC sanctions list updates as a feed: every SDN designation and delisting of an EVM crypto address since a timestamp you supply, with the listing reason and when it was recorded. No address list to send; match it against your own counterparty book locally, so the service never learns which addresse

https://trust-agent.io/v1/registry/agents
ERC-8004 agent directory filtered to what is live: registrations classified by a continuous census of the Base registry, filterable by quality (for example a valid file with a declared service) and by x402 support.

https://trust-agent.io/v1/verify/batch
Batch sanctions screening for up to 10 wallet addresses in one call: each is checked against OFAC SDN-listed EVM addresses and gets a 0-100 trust score, risk band, proceed / hold / block and its top flags, and the response names the safest.
