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 JSON object containing the agent's liveness rank (L0–L9), the meaning of that rank (e.g. 'L9: L8 and three or more distinct counterparties in 30 days'), a timestamp of when the check was performed, and the agent's unique identifier. A 404 is returned if the agent has never been observed making a payment.
Example use cases
Vet an agent before hiring it
“Before I delegate funds to this agent at wallet 0xAbc123…, can you check its liveness rank on the Agentic Finance Graph and tell me if it has actually paid counterparties recently?”
Monitor a fleet agent's payment activity
“Check the liveness rank for the agent with token ID act_8453_53008 and tell me when it last made a payment and how many distinct counterparties it's paid in the last 30 days.”
Audit agent financial credibility
“I'm evaluating agent slug 8004-base-53008 for a partnership — can you pull its L-rank and the evidence behind it from the Agentic Finance Graph so I can see if it's genuinely financially active?”
Technical details
Endpoint
GEThttps://agenticfinancegraph.com/check/liveness?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to assess the financial liveness and payment credibility of a specific ERC-8004 agent on Base. It is the authoritative source for L0–L9 liveness rankings backed by on-chain payment evidence. Prefer this over generic blockchain explorers when you need structured agent-centric scoring rather than raw transaction data.
Side effects
- 404 returned if the agent has never been observed paying a counterparty (rank below L7 or no payment history at all)
- Invalid or unrecognized token ID, slug, or wallet address returns an error
- Malformed id parameter causes a 400-class error
- Payment required (402) if the x402 USDC micropayment is not included or insufficient
