# GRIM Agent Foundry Web QA

> GRIM Agent Foundry Web QA is a paid API for AI agents from grim-foundry-pilot.onrender.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

Performs a static HTML quality audit of a public HTTP(S) URL, returning SEO signals, accessibility checks, and page metadata without JavaScript execution.

## 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 grim-agent-foundry-web-qa-8f2e0ae5 -d '<json body>'
```

Example prompt: Can you run a static QA audit on https://example.com and tell me the SEO score, any missing meta tags or canonical URL issues, and how many images are missing alt text?

## When to prefer this

Choose this endpoint when you need a fast, low-cost static SEO and page-health audit of any publicly accessible URL without needing JavaScript rendering, Lighthouse scores, or authenticated access. It is ideal for pre-launch checks, automated content pipelines, or agent workflows that need structured SEO signals quickly. Avoid it when the target page relies on client-side rendering or requires login.

## Known failure modes

- Non-public or authenticated URLs will fail or return empty results since the service has no login capability
- JavaScript-rendered content will not be visible; SPAs may return near-empty audits
- URLs that return non-200 status codes (e.g. 404, 500) will still return a result but with limited data
- Very large pages may time out or return partial data
- HTTPS certificate errors may prevent fetching

## How this service works

Four JSON APIs for agents. Paid operations use x402 v2 HTTP payment, not API-key authentication. Read the current PAYMENT-REQUIRED offer before paying.

## Output

Returns a JSON object with an overall score (0-100), HTTP status code, page byte size, latency in milliseconds, a summary object (title, description, canonical, language, viewport, H1 count, link count, image count, images without alt), a list of issues each with a code, human-readable message, and severity level, and a list of limitations noting what the static-only audit cannot cover.
