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 the parsed range fields: start (integer byte offset), end (integer byte offset), total (integer total content size), and consistent (boolean indicating whether the range is logically valid). Also includes an evidence block with retained=false, the SHA-256 hash of the input header, and the count of external calls made (always 0).
Example use cases
Validate partial download header
“I got a 206 Partial Content response with the header 'bytes 200-399/1000' — can you parse that and confirm the range is consistent with the total?”
Resume interrupted file transfer
“My download resumed and the server sent back 'bytes 1024-2047/4096' — break that apart so I know exactly where it left off and whether the numbers add up.”
Debug range request mismatch
“Something looks off with this Content-Range header: 'bytes 0-999/500'. Parse it out and flag whether it's actually consistent.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/content-range-parse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, verifiable, no-retention parse of an HTTP Content-Range header into structured numeric fields with a consistency check. Ideal for agents handling resumable downloads, range-request validation, or HTTP protocol debugging where auditability (via input SHA-256 evidence) and exact per-call pricing (no subscription) matter. Prefer it over custom regex parsing when you want a deterministic, externally auditable result at $0.001 USDC per call.
Side effects
- Malformed or unparseable header string returns an error or null fields
- Header exceeding 8192 characters is rejected
- Missing or empty header input causes a validation error
- Unexpected Content-Range format (e.g. non-bytes units) may yield inconsistent=false or error
