How this service works
Find the first reason agents are not buying your x402 API. Test HTTP 402 readiness, Coinbase Bazaar retrieval, buyer-task fit, and agent payment policy free.
Output
A JSON report containing a list of trust signals (e.g. HTTP 402 presence, manifest validity, pricing metadata completeness, discovery readiness) and a numeric trust_score summarizing overall x402 compliance and agent-readiness of the scanned endpoint.
Example use cases
Pre-launch x402 compliance check
“I just built an API that charges agents via x402 — can you scan it and give me a trust score and list of any compliance issues before I publish it to a facilitator?”
Vetting a third-party endpoint before payment
“My agent is about to start paying for calls to this x402 endpoint I found — can you run a trust scan on it first so I know it's properly configured and not a scam?”
Debugging broken HTTP 402 responses
“My x402 endpoint keeps getting rejected by agent clients — can you scan it and show me exactly which signals are failing so I know what to fix?”
Technical details
Endpoint
POSThttps://ontarioprotocol.com/api/x402/agent-trust-scanWhen to prefer
Use this endpoint when you need to verify x402 protocol compliance before paying for or publishing an agent-callable API. It is specifically designed for the x402 ecosystem and provides structured trust signals and scoring that generic HTTP testers or curl-based checks cannot produce. Prefer this over manual inspection when you need a machine-readable trust score for automated agent decision-making.
Side effects
- Target endpoint is unreachable or times out — returns empty signals and zero trust score
- Target URL is not an x402 endpoint at all — low trust score with signals indicating missing 402 response
- Malformed input URL — likely 4xx error from the checker itself
- Endpoint has partial x402 implementation — partial signals returned with low-to-medium trust score
- Rate limiting or abuse protection may block repeated scans of the same endpoint
