How this service works
Before your agent pays an Arc agent: does it actually deliver? Measured, not claimed. Before your agent pays an Arc agent: does it actually deliver? Pass ?agent=<ERC-8004 id>, ?address=0x... or ?url=. One machine-readable record from what we measured, not what it claims: answering now and over 7 days (an hourly call to every endpoint in its registration file), response time, whether its Arc payment offer works, whether a real paid call by us settled, and who pays it on chain (outside payers,…
Output
A single machine-readable JSON record containing: current availability and 7-day uptime (hourly probe results), average response time, whether the agent's Arc x402 payment offer is valid, whether a real paid call by APEX settled successfully, and a list of on-chain addresses that have paid this agent.
Example use cases
Pre-payment agent reliability check
“I'm about to integrate an Arc agent with ID 1085 into my workflow — can you pull its trust record and tell me its uptime, average response time, and whether a real paid call actually settled?”
Vetting an agent by wallet address
“Before my bot sends money to 0xAbC1234567890abcdef1234567890ABCDEF12345, can you check whether that Arc agent has a solid track record — uptime, payment settlement, all of it?”
Screening an agent by its URL
“I found an agent at https://someagent.example.com — can you check its Arc trust record and tell me if it's actually been delivering and whether its payments go through?”
Technical details
Endpoint
GEThttps://apexfaucet.xyz/api/x402/arc-trust?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is about to pay another Arc-registered agent and needs objective, third-party measured evidence of reliability — not self-reported claims. Prefer this over checking an agent's own documentation when you need uptime history, payment settlement confirmation, and on-chain payer provenance in one call.
Side effects
- Agent ID not found in Arc registry — returns empty or 404-style record
- Invalid address format — rejected by query parameter validation
- Agent has never been probed — limited or no historical data returned
- Agent is newly registered — 7-day metrics may be sparse
- Payment check failed if agent's endpoint was unreachable during APEX's probe window
