x402
Content Type 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-Type header value into its media type and parameters, returning a normalized, deterministic result with a pass/advisory status.

How this service works
Content Type Parse: Content Type Parse splits a Content-Type value into media type and parameters from bounded caller-supplied values without an external provider. Call Content Type 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 Type Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only exe…
Output
Returns a versioned deterministic JSON object containing the normalized Content-Type value, the parsed media type, the extracted parameters map, a computed finding summary, and an explicit pass or advisory status indicating whether the header is well-formed and safe to use.
Example use cases
Validate response before caching
“Before I cache this API response, can you parse its Content-Type header 'text/html; charset=utf-8' and tell me the exact media type and whether it passes validation?”
Check Content-Type before redirect
“I'm about to follow a redirect and the response has Content-Type 'multipart/form-data; boundary=----WebKitFormBoundary' — can you split that into its media type and parameters and confirm it looks valid?”
Normalize upstream content type
“An upstream service returned Content-Type 'Application/JSON;Charset=UTF-8' — can you normalize and parse that header so I get the canonical media type and parameters back?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/content-type-parseWhen to prefer
Choose this endpoint when you need deterministic, stateless parsing of a Content-Type header value into its component parts without relying on an external AI model or regex. Ideal for agents that must validate, cache, redirect, or retry based on a caller-supplied HTTP response and need a structured, versioned JSON result with explicit pass/advisory signal rather than a heuristic judgment.
Side effects
- Header string exceeds 8192 character limit — request rejected
- Malformed or unparseable Content-Type value — advisory status returned with finding details
- Missing or empty header field — returns advisory with explanation
- Payment not received or x402 flow incomplete — endpoint not executed
