Development x402 offerings

Validate up to ten JSON documents against JSON Schema draft-07 or 2020-12. Returns per-document validity and actionable errors with instance paths. Runs isolated with bounded time and memory; no remote schema loading or automatic data modification.

Analyze raw HTML you provide and get structured SEO data as JSON: title, meta description, canonical, H1-H6 outline, links, JSON-LD blocks and structural checks (single H1, heading order, duplicates, JSON-LD validity). Use it to audit a page before publishing. No URL fetching, no JavaScript execution. Max 64 KiB of HTML.

Use this service before importing or publishing JSON to check it against a restricted draft-07 schema. Send dataJson and schemaJson as JSON-encoded strings. Max 256 KiB UTF-8 each, depth 32; bounded node and work limits. Supports types, required properties, items, enums and numeric/length bounds. No regex, combinators or external references. Invalid business data returns valid=false.

Invalid business data returns valid=false.

Sends a real request to any URL you provide, attaches an Origin header, and reads back all six standard cross-origin permission headers the server returns. Tells you whether cross-origin requests are enabled at all, whether your specific origin is permitted, and shows every permission value exactly as the server sent it. Useful for finding why a browser is blocking a request, confirming a new deployment is configured correctly, or auditing whether a public API allows credentialed calls.

How many <canvas> elements does the page have? Fetches the URL and counts canvas tags (plus, where relevant, how many have alt/src/href/type attributes), and the page's total element count for scale. Structural audits and template comparisons in one number. $0.01 per page.
