Content Range Parse
x402
Content Range Parse is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Parses a Content-Range HTTP response header and validates total-size consistency, returning a deterministic pass/advisory finding as versioned JSON.

How this service works
Content Range Parse: Content Range Parse parses a Content-Range response and checks total-size consistency from bounded caller-supplied values without an external provider. Call Content Range Parse before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Content Range Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memo…
Output
Returns versioned deterministic JSON containing the parsed Content-Range values (start, end, total), a consistency finding indicating whether the range bounds are coherent with the total size, and an explicit pass or advisory status.
Example use cases
Validate partial download before caching
“I just got back a Content-Range header of 'bytes 200-999/1234' from a server — can you parse it and confirm the total size is consistent before I cache this partial response?”
Pre-retry Content-Range sanity check
“Before I retry this ranged request, can you check whether this Content-Range header 'bytes 500-1499/3000' is well-formed and the bounds make sense?”
Validate Content-Range before redirecting
“I need to forward a partial content response to a client — can you parse 'bytes 0-511/512' and tell me if it passes validation before I redirect the caller?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/content-range-parseWhen to prefer
Use this endpoint when an agent needs to programmatically validate a caller-supplied or third-party Content-Range HTTP header before acting on it — e.g. before caching, retrying, accepting, or redirecting a partial content response. Prefer this over manual parsing when you need a deterministic, stateless, versioned validation result with an explicit pass/advisory status rather than implementing HTTP range parsing logic yourself.
Side effects
- Malformed or missing Content-Range header returns an advisory/fail status with parsing error details
- Header exceeds 8192 character limit resulting in rejection
- Header with wildcard total size (e.g. 'bytes 0-1023/*') may produce an advisory rather than definitive pass
- Payment not received results in 402 response before processing
