Example use cases
Example prompt
“Before I send USDC to this service, can you check the Agent Trust Layer score for https://some-agent-api.example.com and tell me whether I should pay it based on its reliability history?”
Technical details
Endpoint
GEThttps://agent-trust-layer.agent-trust-layer.workers.dev/scoreWhen to prefer
Use this endpoint when an AI agent needs to decide whether to pay an x402-gated or USDC-payable service before committing funds. It is uniquely suited for pre-payment vetting in autonomous agent workflows, especially when the target service has transaction history on Base that can be cross-referenced against live probe results.
Side effects
- No data available for the requested URL or wallet — low confidence score returned
- Invalid URL format — returns validation error
- Endpoint unreachable during live probe — partial score with degraded confidence
- Wallet address not found in any signed transaction history — score defaults to neutral
- Rate limit exceeded — HTTP 402 or 429 returned
