Delx Commerce — HTTP Header Map Normalize
x402
Delx Commerce — HTTP Header Map 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 and sanitizes a map of HTTP headers, lowercasing keys, removing hop-by-hop headers, and returning a clean canonical header object.

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 'ok' (boolean success flag), 'count' (number of headers retained), 'schema' (versioned schema identifier 'delx/util-header-map-normalize/v1'), 'dropped' (array of header keys that were removed), and 'headers' (the cleaned, normalized header map with lowercased keys and hop-by-hop headers stripped).
Example use cases
Sanitize headers before proxying request
“I'm about to relay a request to a third-party API. Can you clean up these headers first — remove anything like 'Connection' or 'Keep-Alive' that shouldn't be forwarded, and normalize the key casing? Here are the headers: {'Content-Type': 'application/json', 'Connection': 'keep-alive', 'Authorization': 'Bearer abc123'}.”
Normalize agent-collected headers for logging
“My agent scraped some response headers but the casing is all over the place. Can you normalize them so all keys are lowercase and any hop-by-hop headers are dropped? Headers: {'Content-Type': 'text/html', 'TRANSFER-ENCODING': 'chunked', 'X-Request-ID': '99f2'}.”
Prepare headers for downstream service call
“Before I pass these headers to the next step in my pipeline, can you run them through normalization to drop connection-level headers and lowercase everything? Headers: {'Accept': 'application/json', 'connection': 'upgrade', 'host': 'api.example.com'}.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/header-map-normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to canonicalize HTTP headers before forwarding, logging, or storing them — especially to remove proxy-specific hop-by-hop headers (Connection, Transfer-Encoding, etc.) and standardize key casing. It is ideal for lightweight, pay-per-call header sanitization without needing to run custom normalization logic. Use it instead of writing your own header-cleaning function when operating in an agent pipeline that already supports x402 micropayments on Base or Solana.
Side effects
- Invalid or non-object 'headers' input may cause a 400 error
- Empty headers object returns ok:true with count:0 and empty headers map
- Network or payment failure returns a 402 or 5xx response
- Malformed JSON body returns a parse error
