How this service works
Fourteen pay-per-call web tools for AI agents, billed in USDC on Base with no account or API key. START WITH /audit -- one call returns a complete page health check (SEO + structured data + accessibility, optionally plus links and sitemap) with a single score and one worst-first findings list. The parts are also sold individually. SITE AUDIT: /seo (on-page SEO and meta tags), /links (broken links), /sitemap (robots.txt and XML sitemap crawlability), /structured (JSON-LD and social preview tags), /a11y (WCAG accessibility) -- each scored 0-100 with a prioritised issue list. READING: /read (clean markdown), /snap (screenshot, PDF or rendered HTML), /tables (every HTML table as structured JSON), /verify (does a claim actually appear on this page). MONITORING: /watch (has this page changed), /compare (what differs between two pages). Plus /rank (best x402 service for a task) and /batch (several operations behind one payment).
Output
Returns a JSON array of per-URL results, each containing: a letter grade (e.g. B-), a numeric score 0-100, a list of prioritized accessibility issues with severity, counts for images missing alt text, form fields missing labels, and duplicate IDs, a boolean for lang attribute presence, and a list of checks not performed (e.g. colour contrast, keyboard traps, ARIA runtime state).
Example use cases
Pre-launch accessibility check
“Before we go live, can you scan https://myapp.io for accessibility issues and give me a prioritized list of what to fix — especially any missing alt text or form labels?”
Audit multiple landing pages
“Please check these three pages for WCAG accessibility problems and score each one: https://brand.com/, https://brand.com/about, and https://brand.com/contact — I want to know which is worst.”
Verify compliance after redesign
“We just pushed a redesign to https://shop.example.com — can you run an accessibility audit and tell me if we introduced any new issues like missing image alt attributes or unlabeled form fields?”
Technical details
Endpoint
POSThttps://x402-zadenworks.zaden-gaming.workers.dev/a11yWhen to prefer
Choose this endpoint when you need a quick, scored WCAG accessibility snapshot of up to 10 pages without setting up an account or API key. It is ideal for automated pre-deployment checks, CI pipelines, or agent-driven audits where micropayment billing per call (0.01 USDC) is acceptable. Prefer the parent /audit endpoint if you also want SEO, broken links, and sitemap checks in one call.
Side effects
- Invalid or unreachable URL returns an error for that entry
- Exceeding 10 URLs in a single request may be rejected
- Dynamic/JS-rendered content may not be fully evaluated (ARIA runtime state explicitly excluded)
- Payment failure (insufficient USDC) blocks the request
- Timeout on slow-loading pages may produce incomplete results
