How this service works
Email checks, DNS and email-authentication audits, website contact extraction, SEO audits, URL to Markdown and Swedish validators, paid per call in USDC with x402.
Output
Returns a JSON object with an overall SEO score (0-100), page title and length, H1/H2 counts, meta description and length, canonical URL and whether it's self-referencing, indexability flag, noindex source, hreflang tags, viewport, robots meta, word count, links breakdown (internal/external/nofollow), images (total and missing alt), security headers (CSP, HSTS, X-Frame-Options, referrer policy, etc.), Open Graph and Twitter Card data, JSON-LD schema types, detected technologies, redirect chain, and a list of issues with code, message, and severity.
Example use cases
Pre-launch landing page SEO check
“Before we launch, can you audit https://startup.io/product and tell me the SEO score, whether it's indexable, and what issues like missing meta descriptions or H1 problems I need to fix?”
Competitor page technical analysis
“I want to know how https://competitor.com/pricing stacks up technically — can you pull an SEO audit showing their title, canonical setup, Open Graph tags, security headers, and any issues flagged?”
Client site monthly health report
“Run a site audit on https://clientsite.com/home and give me the full breakdown: SEO score, indexability, image alt text issues, redirect chain, and any warnings or errors found.”
Technical details
Endpoint
GEThttps://agentkit-x402.erikssonanton2001.workers.dev/v1/site-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured, pay-per-call SEO and technical audit of a single webpage without setting up a full crawl tool. Ideal for spot-checks on landing pages, competitor pages, or client sites where you want score, indexability, metadata completeness, and security headers in one call. At $0.02 USDC per call via x402, it suits agent workflows that audit pages on-demand without subscriptions.
Side effects
- Invalid or unreachable URL returns an error response
- Non-200 status pages may return partial data
- Payment of 0.02 USDC via x402 required; missing or invalid payment results in 402 response
- Rate limiting or Cloudflare Workers timeout for very slow target sites
- Dynamic JavaScript-rendered content may not be fully parsed
