# Delx Commerce HTTP Request Canonicalize

> Delx Commerce HTTP Request Canonicalize is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-01).

Canonicalizes an HTTP request object into a normalized, credential-stripped fingerprint for verifiable, deterministic comparison

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-http-request-canonicalize-5ea38dfd -d '<json body>'
```

Example prompt: Canonicalize this HTTP request for me — it's a GET to https://api.example.com/jobs?a=1&b=2 with an Accept: application/json header — I need a stable fingerprint with credentials stripped so I can deduplicate it.

## When to prefer this

Choose this endpoint when you need a deterministic, credential-stripped fingerprint of an HTTP request for purposes such as deduplication, caching, audit logging, or replay detection. It is ideal when you want a pay-per-use, no-signup utility that returns a verifiable canonical form with USDC micropayment settlement on Base or Solana via x402.

## Known failure modes

- Missing or malformed request object returns a validation error
- Invalid URL format causes canonicalization failure
- Unsupported HTTP method may produce unexpected normalization
- Empty body results in default SHA256 hash for empty content
- Network timeout or upstream service unavailability returns 5xx

## 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 schema identifier (delx/util-http-request-canonicalize/v1), the normalized request (with URL, method, headers, and body_sha256), a deterministic hex fingerprint string, and a boolean confirming credentials were removed.
