HTTP Version Normalize
x402
HTTP Version Normalize is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-16).
Normalizes common HTTP protocol version strings (e.g. 'HTTP/1.1', 'http 2', 'h2') into a canonical, deterministic form and returns a pass/advisory status.

How this service works
HTTP Version Normalize: HTTP Version Normalize normalizes common HTTP protocol version spellings from bounded caller-supplied values without an external provider. Call HTTP Version Normalize 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 HTTP Version Normalize as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-o…
Output
Returns a versioned deterministic JSON object containing: the normalized (canonical) HTTP version string, the computed finding describing what was parsed, and an explicit pass or advisory status indicating whether the input was a recognized, valid HTTP protocol version.
Example use cases
Sanitizing gateway input versions
“A caller just submitted 'HTTP/2.0' as a protocol version to my API gateway — can you normalize it and tell me if it passes before I route the request?”
Validating HTTP version before caching
“Before I cache this web response, normalize the version string 'h2' and tell me whether it's a recognized, canonical HTTP version.”
Audit log standardization
“I have the HTTP version 'HTTP 1.0' from a legacy client — normalize it to its canonical form and tell me if it's advisory or a clean pass so I can log it consistently.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/http-version-normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, stateless, deterministic check on an HTTP protocol version string before accepting, caching, redirecting, or retrying a web response. It is ideal when you want a versioned, auditable JSON result with an explicit pass/advisory classification rather than writing your own regex or parser. Prefer it over a general-purpose string validator when the domain is specifically HTTP protocol versions.
Side effects
- Input string too long (exceeds maxLength 8192 — unlikely in practice but schema-enforced)
- Completely unrecognizable string returns advisory status rather than a hard error
- Missing or null version field may return a validation error
- Payment failure via x402 protocol prevents call completion
