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 a 'result' containing an array of parsed tokens and a normalized header string, plus an evidence block confirming no data was retained (retained: false), the SHA-256 hash of the input, and the count of external calls made (always 0). Also includes schema identifier, status ('pass'), and operation name.
Example use cases
Validate proxy Connection header
“I'm debugging a reverse proxy and want to check what tokens are in this Connection header string: 'keep-alive, Transfer-Encoding' — can you break it down into individual directives and show me the normalized version?”
Normalize header before forwarding
“Before my agent forwards this HTTP request, I need to tokenize the Connection header value 'close, upgrade' so I can strip hop-by-hop headers correctly — can you parse it for me?”
Audit header compliance in pipeline
“I have a Connection header from an incoming request that reads 'keep-alive' — can you parse it into tokens and confirm it's well-formed so I know it's safe to pass downstream?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/connection-header-tokenize?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, verifiable, privacy-preserving parse of an HTTP Connection header with cryptographic evidence of non-retention. Prefer it over writing custom parsing logic when you need an auditable result with an input hash for compliance or debugging pipelines. Particularly suited for AI agents that need deterministic, pay-per-use HTTP utility operations without account setup.
Side effects
- Input header string exceeds 8192 character limit — request rejected
- Malformed or empty header value may return empty token array
- Payment failure via x402 protocol prevents API execution
- Network timeout before processing completes
