Delx Commerce — HTTP Status Retry Classifier
x402
Delx Commerce — HTTP Status Retry Classifier is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Classifies whether an HTTP request with a given method and status code is retryable, given a set of retry-eligible status codes

How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing a 'retryable' boolean, the original method and status echoed back, a pass/fail status, an operation identifier ('web_reliability:status_retry_classify'), and cryptographic evidence including the SHA-256 hash of the input and a flag confirming no data was retained externally.
Example use cases
Retry decision for failed API call
“My outbound API call was a GET that came back with a 503 — given that I retry on 429, 500, 502, 503, and 504, should I retry it?”
Post request retry eligibility check
“I have a POST request that returned a 429. My retry-eligible statuses are 429 and 503 only — is this one retryable?”
Dynamic retry gate in agent workflow
“Before my agent retries a failed request, check if a PUT that got a 500 is retryable, assuming I allow retries on 500 and 502.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/status-retry-classify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a stateless, verifiable, pay-per-use computation to determine HTTP retry eligibility without building or maintaining your own retry classification logic. Ideal for AI agents that need auditable, tamper-evident retry decisions with cryptographic evidence of non-retention, especially in regulated or multi-party workflows where proof of computation matters. Prefer this over rolling your own if you need the SHA-256 input hash for audit trails.
Side effects
- Invalid or missing 'method' field returns a validation error
- Status code outside valid HTTP range may produce unexpected classification
- Empty retry_statuses array will always return retryable: false
- Malformed request body returns a 4xx client error
- Payment failure via x402 protocol blocks request execution
