Delx HTTP Retry Plan

x402

Delx HTTP Retry Plan is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).

Returns an optimal HTTP retry strategy (backoff algorithm, max attempts, jitter, idempotency) for a given HTTP method and response status code

How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

Output

A JSON object containing the recommended retry strategy including: the HTTP method, schema version, any warnings, the backoff strategy name (e.g. exponential_full_jitter), whether the request is retryable, whether it is idempotent, the original status code, the maximum number of retry attempts, and whether to respect the Retry-After header.

Example use cases

Agent retry logic for rate-limited APIs

“My agent keeps hitting 429 Too Many Requests on a POST endpoint that isn't idempotent — can you figure out the right retry strategy for it, including how many times to retry and what kind of backoff to use?”

Safe retry plan for timed-out GET requests

“I'm getting 408 Request Timeout errors on GET calls to an external API — tell me the recommended retry strategy including whether it's safe to retry and how to back off.”

Retry policy for server errors on DELETE requests

“My DELETE request returned a 500 Internal Server Error — is that retryable, and if so what's the right backoff strategy and maximum number of attempts I should use?”

When to prefer

Choose this endpoint when an AI agent or automated HTTP client needs a deterministic, best-practice retry plan for a specific HTTP status code and method combination, especially when building resilient API integrations or agent workflows that must handle transient failures gracefully. It is preferable over hardcoded retry logic because it encodes idempotency awareness and HTTP semantics.

Side effects

Invalid status code outside 100-599 range returns a validation error
Unsupported HTTP method may return an unexpected or generic strategy
Missing required fields may result in a 400 Bad Request
Payment failure via x402 protocol prevents response delivery
