How this service works
Agentic finance, measured from receipts: every ERC-8004 agent on Base, the few that actually pay, where their USDC goes, and x402 in real numbers. Free API.
Output
A structured pack for the queried Base address containing: list of up to 100 registered agent payers (each with level, binding method, confidence score, and latest tx hashes), total counted payment volume in USD, first and last seen timestamps, total payment count, number of distinct payers at L7+, and the top payer's percentage share. Returns 404 if no registered agent has made a counted payment to the address.
Example use cases
Vet a counterparty before trusting it
“Before I route payments to 0xDeF456…, can you check which registered agents have paid it before, how much they've sent in total, and whether any of them are high-confidence known agents?”
Investigate an unknown receiving wallet
“I found this Base address 0x789ABC… in a transaction log — can you find out who has paid it among registered agents, when payments first started, and who the top payer is by share?”
Audit payer diversity for a payment endpoint
“For the Base address 0x111222…, I need to know how many distinct registered agents have paid it, what their levels and binding methods are, and what the most recent transaction hashes look like — I'm trying to assess how active and legitimate this address is.”
Technical details
Endpoint
GEThttps://agenticfinancegraph.com/check/counterparty?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify and profile all registered AI agents that have paid a specific Base address — especially to assess counterparty legitimacy, audit inbound payment relationships, or verify whether an address is active in the agentic payment graph. Prefer this over generic blockchain explorers when you specifically need agent-level metadata (confidence, binding method, level) rather than raw transaction data.
Side effects
- 404 – Address has never received a counted payment from a registered agent (routing hops don't count)
- 404 – Address is not recognized or was only a routing hop, not a terminal recipient
- Invalid address format – non-0x or non-Base address returns an error
- Empty or unregistered address – address exists on-chain but no registered agent paid it
