How this service works
Vertrauensprüfung fremder x402-Endpunkte
Output
Returns a trust assessment of the given x402 endpoint, including a trust score, identified risk signals or red flags, legitimacy indicators, and an overall recommendation on whether the endpoint is safe to call and pay.
Example use cases
Pre-payment safety check for unknown API
“I found this x402 endpoint at https://unknown-api.example.com/v1/generate that charges $0.05 per call — can you run it through the x402 Radar to see if it's legitimate before my agent starts paying it?”
Automated trust gating in multi-agent workflow
“My agent pipeline is about to call a third-party x402 service it's never used before. Check the endpoint https://thirdparty.example.com/v1/infer with the x402 Radar and only proceed if it passes the trust check.”
Comparing trustworthiness of two x402 providers
“I'm choosing between two x402 endpoints for image processing — run both https://provider-a.example.com/img and https://provider-b.example.com/img through the x402 Radar and tell me which one looks safer to use.”
Technical details
Endpoint
POSThttps://tools.halowerk.com/v1/x402/radarWhen to prefer
Use this endpoint whenever an AI agent is about to call an unfamiliar or untrusted x402 service, especially before making any payment. This is the right choice when building safety gates in agentic workflows that dynamically discover and pay x402 APIs, or when evaluating third-party x402 providers for the first time. Prefer this over manual inspection when operating at scale or in automated pipelines where human review is not feasible.
Side effects
- Endpoint URL is unreachable or returns no metadata — partial or failed analysis
- Unknown or newly registered x402 endpoint with insufficient signals — low-confidence verdict
- Malformed URL input — validation error returned
- Endpoint actively mimics legitimate providers — potential false positive on trust score
- Rate limit exceeded — error response if too many checks in short succession
