How this service works
x402-Werkzeuge für autonome Agenten.
Output
Returns a JSON object with per-endpoint results including reachability, latency percentiles, trust rating (solide/unklar/auffaellig), payment challenge validity, price in USDC, discovery presence across llms.txt/OpenAPI/Bazaar/agent card, optional price change history, downtime events, and a summary aggregating totals across all checked endpoints.
Example use cases
Audit own x402 endpoints before launch
“Run a full radar scan on my x402 endpoint at https://tools.netzhandwerker.de/v1/x402/radar and tell me if the payment challenge is valid, whether it's properly listed in the Coinbase Bazaar, and if there are any discovery gaps I should fix.”
Discover and vet Bazaar x402 endpoints
“Pull up to 10 endpoints from the Coinbase Bazaar and do a quick radar check on each — I want to know which ones are reachable, payable, and trustworthy before I integrate any of them into my agent.”
Monitor third-party x402 API health
“Can you do a quick scan on these five x402 APIs I depend on and flag any that are unreachable, have pricing inconsistencies, or look suspicious: [list of URLs]?”
Technical details
Endpoint
POSThttps://tools.netzhandwerker.de/v1/x402/radarWhen to prefer
Use this endpoint when you need to programmatically audit x402 payment-gated APIs for agent use — especially when validating whether endpoints you plan to call are actually reachable, correctly priced, and have valid payment challenges. Prefer the quick depth for fast health checks and full depth when you need historical pricing and facilitator verification. Use the discover flag when you want to pull and vet endpoints directly from the Coinbase Bazaar rather than supplying your own list.
Side effects
- Endpoint URL unreachable — marked reachable:false with no latency data
- Invalid or missing x402 payment challenge — challenge_valid:false
- Pricing inconsistency detected between challenge and advertised price — price_consistency:false
- Too many endpoints supplied (>20) — request rejected
- Full depth scan timeout for slow endpoints (~12s per endpoint)
- Bazaar discovery fails if Coinbase infrastructure is unavailable
