Delx Commerce — Retry-After Header Parser
x402
Delx Commerce — Retry-After Header Parser 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).
Parses an HTTP Retry-After header value and computes the delay in seconds and the absolute retry timestamp epoch.

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: delay_seconds (how long to wait in seconds), retry_at_epoch (absolute Unix epoch when to retry), status ('pass' or failure), operation label, and an evidence block confirming no data retention, number of external calls made, and a SHA-256 hash of the input for auditability.
Example use cases
Rate-limited API retry scheduling
“I got a 429 Too Many Requests from a downstream API and the Retry-After header says 'Wed, 03 Jul 2024 15:28:40 GMT'. My current epoch is 1720000000 — can you parse that and tell me exactly how many seconds to wait and when to retry?”
Agent loop backoff calculation
“My agent hit a rate limit and received a Retry-After value of '300'. The current epoch is 1720000000. Parse that and give me the delay in seconds and the exact epoch timestamp when I should try again.”
HTTP retry header normalization
“I need to normalize a Retry-After header value that might be either a number of seconds or an HTTP date string. The value is '120' and my current epoch is 1720000050 — compute the delay and the retry-at epoch for me.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/retry-after-parse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to deterministically parse HTTP Retry-After headers — whether numeric seconds or HTTP date strings — into a concrete wait duration and retry epoch, especially when auditability (input hash, no retention guarantee) and micro-cost pay-per-call pricing matter. Prefer this over hand-rolling parsing logic when you need verifiable, consistent output for retry scheduling in agentic workflows.
Side effects
- Malformed or unparseable Retry-After value returns an error status
- Missing required 'value' field causes a validation error
- now_epoch not provided may cause incorrect absolute timestamp calculation
- Value exceeding 8192 characters is rejected
- Invalid date string format in Retry-After header may cause parse failure
