# CodePulse Security HTTP Headers Checker

> CodePulse Security HTTP Headers Checker is a paid API for AI agents from codepulse-api.hahavoid0.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Analyzes a URL's HTTP security headers and returns a security score with details on CSP, HSTS, and other header configurations.

## Facts

- Endpoint: POST https://codepulse-api.hahavoid0.workers.dev/security/http-headers
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

- Tags: x402
- Canonical page: https://www.zero.xyz/c/codepulse-security-http-headers-checker-1c112d39
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_7knkvFCMIkqxqB2x7aNc6

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 codepulse-security-http-headers-checker-1c112d39 -d '<json body>'
```

Example prompt: Can you check the HTTP security headers on https://example.com and tell me if they have HSTS and CSP set up properly, and what the overall security score is?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call HTTP security header analysis without setting up API keys. It's ideal for spot-checking individual URLs for CSP, HSTS, and other security headers with a scored output. Prefer this over manual header inspection tools when you need machine-readable results with confidence ratings inside an automated agent workflow.

## Known failure modes

- Invalid or unreachable URL returns an error or unsupported flag
- URL with unusual schemes (non-HTTP/HTTPS) may not be supported
- Rate limiting or payment failure via x402 results in 402 response
- Ambiguous or redirect-heavy URLs may reduce confidence rating
- Temporary network issues at the target site may cause incomplete header reads

## How this service works

Queries target URL headers to score security configurations (HSTS, CSP, X-Frame-Options).

## Output

Returns a JSON object with a numeric security score (0-100), a breakdown of specific header statuses (e.g. csp: false, hsts: true), a list of warnings for missing or misconfigured headers, a 'supported' boolean, and a confidence level (e.g. 'high') along with a data freshness date.
