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.
Example use cases
Landing page SEO pre-launch check
“Before we go live, can you audit https://acme.com/new-landing and tell me if we're missing a meta description, whether the title length is in the right range, and what our overall QA score looks like?”
Blog post metadata validation
“Check https://myblog.com/post/how-to-bake-bread for basic SEO hygiene — is there a canonical tag, does it have an H1, and are there any images without alt text?”
Competitor page analysis
“Do a static audit on https://competitor.com/pricing and give me their page score, title, description, and any SEO issues you find.”
Technical details
Endpoint
POSThttps://grim-foundry-pilot.onrender.com/v1/web-qaWhen to prefer
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.
Side effects
- 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
