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 with a 'result' field containing the ordered list of codings and a boolean indicating whether chunked is last, a status of 'pass' or 'fail', an operation label, and an evidence block confirming no data retention, no external calls made, and the SHA-256 hash of the input header.
Example use cases
Validate proxy server encoding headers
“My reverse proxy is sending 'deflate, gzip, chunked' as the Transfer-Encoding header — can you check if that's a valid ordering and whether chunked is correctly the last coding?”
Debug web server HTTP compliance
“I'm seeing weird responses from my web server with Transfer-Encoding set to 'chunked, gzip' — can you parse that header and tell me if chunked is in the right position?”
Automated HTTP conformance testing
“As part of my API reliability check, validate this Transfer-Encoding header value: 'gzip, chunked' — I need to know all the codings listed and whether it's RFC-compliant.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/transfer-encoding-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, auditable, stateless parse of an HTTP Transfer-Encoding header with cryptographic evidence of no data retention — ideal for automated web reliability checks, HTTP conformance testing pipelines, or agent workflows that need verifiable header validation without standing up custom parsing logic.
Side effects
- Malformed or non-string header input may result in a parse error or unexpected coding list
- Header exceeding 8192 characters will be rejected
- Payment failure via x402 will prevent execution
- Empty input may return an empty codings array with chunked_last false
