How this service works
Web standards and time reference for AI agents: HTTP status codes with what the client should do, retry semantics, MIME types and content-type matching, request-method safety and idempotency, plus deadline arithmetic - time until a moment, weekday and business-day checks, duration conversion and Unix timestamps. Pay per call in USDC on Base via x402 or USDC on Tempo via MPP. No signup, no API key, no KYC.
Output
Returns structured retry advice for the given HTTP method and status code, including whether the request is safe to retry, suggested wait/backoff strategy, and whether the operation is considered idempotent, helping agents and HTTP clients make correct decisions about request retries.
Example use cases
API retry logic in an agent
“My agent got a 429 response on a GET request — is it safe to retry, and what retry strategy should I follow?”
Safe retries for destructive methods
“I'm making a DELETE request and got back a 503 — should I automatically retry it or is that dangerous?”
Debugging unexpected HTTP errors
“What should my HTTP client do when it receives a 502 for a HEAD request — retry immediately, back off, or give up?”
Technical details
Endpoint
GEThttps://webref.johnaio281.workers.dev/api/web/retry_advice?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent or HTTP client needs authoritative, structured guidance on whether and how to retry a failed HTTP request for safe/idempotent methods (GET, HEAD, DELETE). Prefer this over hardcoded retry logic or LLM reasoning about HTTP semantics, especially when correctness and standards-compliance matter. Particularly useful for agents operating autonomously that need to handle transient failures without human guidance.
Side effects
- Missing required 'input.method' or 'input.type' fields returns a validation error
- Providing an HTTP method not in the allowed enum (GET, HEAD, DELETE) returns an error
- Providing a non-HTTP type value returns an error
- Invalid or unrecognized status code may return a generic or null advice response
- Payment failure via x402 or MPP results in 402 response with no data returned
