# Delx Commerce Cookie Security Check

> Delx Commerce Cookie Security Check 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).

Validates HTTP Set-Cookie headers against configurable security policies (Secure, HttpOnly, SameSite attributes) and returns a structured pass/fail result.

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-cookie-security-check-2781559c -d '<json body>'
```

Example prompt: Check this Set-Cookie header for me and make sure it has Secure and HttpOnly set, and that SameSite is either Strict or Lax: 'sid=abc123; Path=/; Secure; HttpOnly; SameSite=Lax'

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call, no-signup cookie security validator that returns structured, verifiable results with cryptographic evidence of non-retention. Ideal for agents running automated security audits, CI pipelines, or one-off compliance checks where you don't want to manage an account or pay for a subscription. Prefer over rolling your own parser when you need a canonical, auditable record of the check.

## Known failure modes

- Malformed or unparseable cookie header string may result in an error or failed validation
- Header exceeding 8192 characters will be rejected
- Invalid SameSite values not in the allowed_same_site list will cause policy failure
- Missing required attributes (Secure/HttpOnly) when required flags are true will return status 'fail'
- Payment failure via x402 will block the request before processing

## 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 the parsed cookie name, its attributes (path, secure, httponly, samesite), the raw value length, a boolean secure_policy_passed, and an overall status of 'pass' or 'fail'. Also includes an evidence block with a SHA-256 hash of the input and confirmation that no data was retained and no external calls were made.
