How this service works
AEO evidence checks, SEO audits, readable reports and web data for agents. Tools from 0.01 USDC; page audits 0.25; five-page audit packs 1.00 USDC via x402.
Output
Returns a JSON object containing the page title, a list of named SEO checks each with a status (pass/warning/fail) and a human-readable detail string, aggregate pass and warning counts, the fetch timestamp, and a list of limitations (e.g. static HTML only, no JavaScript execution). Covers title length, description length, canonical declaration, HTML language, H1 count, image alt coverage, indexing directives, and Open Graph title and image.
Example use cases
Landing page pre-launch SEO check
“Before we go live, can you audit https://mystore.com/new-collection and tell me if the title, meta description, canonical, and Open Graph tags are all set up correctly?”
Blog post optimization review
“I just published a post at https://techcrunch.com/2024/05/01/ai-roundup — can you check its on-page SEO and flag any warnings around headings, alt text, or meta tags?”
Client website SEO report
“I need a quick SEO health check on https://clientsite.io/about — check the title, description length, H1 usage, indexing directives, and Open Graph image, and summarize what passes and what needs attention.”
Technical details
Endpoint
POSThttps://agentpage402-demo.onrender.com/v1/seo?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.01 USDC), machine-readable on-page SEO heuristic check on a single public URL — especially when you want structured pass/warning/fail results per check rather than a narrative report. It is best suited for static HTML pages; avoid it for fully JavaScript-rendered SPAs where meta tags are injected at runtime. Prefer it over generic scraping tools when the specific goal is SEO metadata validation.
Side effects
- URL is not publicly accessible or returns a non-200 status — audit cannot proceed
- URL uses non-standard port or contains credentials — rejected by input validation
- Page is JavaScript-rendered — only static HTML is analyzed, dynamic content is missed
- Open Graph or meta tags are injected by JavaScript — not detected in static parse
- Malformed or extremely large HTML — may cause incomplete parsing
- Network timeout fetching the target URL — returns an error response
