Delx Commerce HTTP Version Normalize
x402
Delx Commerce HTTP Version Normalize is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Normalizes an HTTP version string (e.g. '2.0', 'HTTP/1.1') into a canonical short form and validates whether it is a recognized HTTP version.

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 containing the normalized version string (e.g. '2'), a boolean 'recognized' flag indicating whether the version is a known HTTP version, a status field ('pass'), the operation name ('web_reliability:http_version_normalize'), and an evidence block with a SHA-256 hash of the input, a 'retained: false' flag confirming no data is stored, and a count of external calls made (0).
Example use cases
Validate HTTP version from request logs
“I have a bunch of HTTP version values from my server logs like 'HTTP/1.1' and '2' — can you normalize each one to its canonical short form and flag which ones are actually recognized HTTP versions?”
Sanitize user-supplied protocol strings
“A user submitted the string 'HTTP/2.0' as their preferred protocol — can you normalize it to the standard canonical form so I know exactly which version they mean?”
Web reliability audit of version tags
“We're auditing our API gateway config and need to check whether the version tag 'h2' is a recognized HTTP version and what its normalized canonical form is.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/http-version-normalize?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, verifiable, pay-per-result normalization of HTTP version strings with cryptographic evidence of non-retention — ideal for agents that need auditable web protocol validation without provisioning API keys or subscriptions. Prefer this over custom parsing logic when you need consistent canonical output and proof of processing.
Side effects
- Malformed or empty version string may still return a result with recognized: false
- Input exceeding 8192 characters will be rejected
- Network or payment failures via x402 may prevent the call from completing
- Unexpected version formats may not be normalized as expected
