x402 Broken Endpoint Detector
x402
x402 Broken Endpoint Detector is a paid API for AI agents from x402.dailyelo.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).
Returns a list of x402-protocol endpoints on Base that are currently broken (down or misconfigured, not returning a valid 402 response), so agents can avoid routing paid requests to dead endpoints.

How this service works
Which x402 endpoints on Base are broken RIGHT NOW (down or misconfigured — not returning a valid 402). A real share of listed endpoints are dead; call this before routing a paid request so your agent never pays into a broken endpoint. No args = full broken list; ?domains=a.com,b.com = watch your dependencies; ?since=<unix> = incremental. Free-probe measurement, objective, machine-readable.
Output
A machine-readable list of x402 endpoints on Base that are currently broken (down or not returning a valid 402), including health status for watched domains. Supports incremental polling via a unix timestamp and filtering by domain list or result limit.
Example use cases
Example prompt
“Before I pay for any of these x402 services, check which ones on a.com and b.com are currently broken or misconfigured and not returning valid 402 responses — I don't want to burn money on dead endpoints.”
Technical details
Endpoint
GEThttps://x402.dailyelo.com/v1/reliability/brokenWhen to prefer
Use this endpoint immediately before routing any paid x402 request on Base to avoid paying into broken or misconfigured services. Prefer this over general uptime monitors because it specifically probes for valid 402 responses, not just TCP reachability. Use the ?domains= filter when monitoring specific dependencies, and ?since= for incremental polling in automated workflows.
Side effects
- Invalid 'since' unix timestamp format returns 400 error
- 'domains' parameter with malformed domain strings may return empty or partial results
- Limit exceeding 2000 is clamped or rejected
- Endpoint itself may be temporarily unavailable returning 5xx
- No broken endpoints found returns empty list (not an error)
