How this service works
Thirty x402 v2 pay-per-call APIs by 100BTC. Listing data is generated from each live HTTP 402 challenge and runtime Bazaar schema.
Output
Returns a JSON object with a 'decision' field (e.g. 'USE' or 'AVOID'), a 'reliability_score' (0-100), 'metrics' containing reachability boolean, HTTP status code, latency in milliseconds, and check timestamp, plus a human-readable 'reasons' array explaining the assessment.
Example use cases
Pre-flight check before paid API call
“I'm about to call a pay-per-call API at https://example-x402-api.com/api/data but I don't want to waste money if it's down — can you probe it with a GET request first and tell me if it's responding and what the latency looks like?”
Agent routing decision for redundant endpoints
“I have two backup API endpoints I could route to — can you check both https://api-primary.example.com/infer and https://api-backup.example.com/infer with POST requests and tell me which one has the better reliability score right now?”
Monitoring x402 marketplace listing health
“I listed my x402 API at https://myservice.example.com/api/oracle — can you verify it's still returning a 402 response as expected and give me the current latency and reliability score?”
Technical details
Endpoint
POSThttps://vps-fc89c157-1.taila28d02.ts.net:10000/api/oracle?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a live, real-time probe of whether a specific URL is responding before committing resources or payments to calling it. Particularly valuable before invoking x402 pay-per-call APIs where a failed call still costs money. Prefer this over passive uptime monitors when you need an on-demand decision ('USE' vs 'AVOID') with latency data at the moment of routing.
Side effects
- Target URL is unreachable or times out — returns reachable: false with error context
- Invalid or malformed target_url input — likely 4xx validation error
- Target returns unexpected non-standard status code — still reported but may lower reliability score
- Network-level errors from the oracle server itself — service unavailability
