How this service works
Evidence-backed npm package upgrade decisions for coding agents.
Output
Returns a JSON object with a summary field containing a successRate value (e.g. 0.5) representing the proportion of successful webhook deliveries from the submitted batch.
Example use cases
Monitoring webhook health after deployment
“We just deployed a new webhook handler and I have 50 delivery records from the past hour — mix of 200s, 500s, and timeouts. Can you analyze these and tell me the success rate so I know if the deployment is stable?”
Debugging unreliable third-party webhook
“I've been logging all incoming webhook deliveries from our payment provider for the past day — about 80 attempts with various status codes and latencies. Can you assess how reliable their delivery has been and give me a success rate?”
Pre-production webhook reliability check
“Before we go live, I want to sanity-check our staging webhook: I have 30 test delivery results with status codes and response times. Can you compute the reliability and success rate so I know if we're ready to launch?”
Technical details
Endpoint
POSThttps://x402-safe-upgrade-api.onrender.com/v1/webhook-reliability-assessment?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, evidence-backed reliability score computed from raw webhook delivery logs (status codes and optional latencies). Prefer it over manual log analysis when you want a structured success rate summary for up to 250 delivery attempts in a single call.
Side effects
- Empty or missing deliveries array — returns validation error
- Deliveries array exceeds 250 items — rejected due to maxItems constraint
- Missing required statusCode field in a delivery object — schema validation failure
- Malformed request body — 400 bad request
- Service unavailable on render.com cold start — potential timeout or 503
