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).","url":"https://x402-zadenworks.zaden-gaming.workers.dev/structured","method":"POST","headers":{},"bodySchema":{"type":"object","$schema":"https://json-schema.org/draft/2020-12/schema","required":["input"],"properties":{"input":{"type":"object","required":["type","method","bodyType","body"],"properties":{"body":{"type":"object","required":["urls"],"properties":{"urls":{"type":"array","items":{"type":"string"},"description":"Pages to validate (max 10)"}}},"type":{"type":"string","const":"http"},"method":{"enum":["POST"],"type":"string"},"bodyType":{"enum":["json","form-data","text"],"type":"string"}},"additionalProperties":false},"output":{"type":"object","required":["type"],"properties":{"type":{"type":"string"},"example":{"type":"object"}}}}},"responseSchema":{"type":"json","example":{"results":[{"url":"https://example.com/","grade":"B-","score":80,"issues":["No Twitter Card tag found -- X/Twitter will fall back to Open Graph tags or show no preview."],"severity":"warning","hasOpenGraph":true,"hasTwitterCard":false,"structuredDataFound":true,"structuredDataTypes":["Organization"]}]}},"example":null,"exampleRequest":null,"tags":["x402"],"displayCostAmount":"0.01","displayCostAsset":"USDC","priceDynamic":false,"priceHint":null,"priceStatus":"priced","priceSource":"registry","requiresHandshake":false,"reviewCount":0,"rating":{"score":"0.00","successRate":"0.00","reviews":0,"stars":null,"state":"unrated"},"availabilityStatus":"unknown","priceObserved":null,"sessionDeposit":null,"pricing":{"kind":"static","summary":"$0.01/call","primary":{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.01","per":"call","confidence":"exact"},"accepted":[{"kind":"static","protocol":"x402","network":"base","amountUsd":"0.01","per":"call","confidence":"exact"}]},"paymentMethods":[{"uid":"pm_wrTdJjfhAZPZ8EsPq27v7","protocol":"x402","methodType":"crypto","chain":"base","mode":"charge","costAmount":"0.01","costPer":"request","priority":0,"asset":null,"unit":"request","depositMicros":null,"planRef":null}],"brandName":null,"brandSlug":null,"brandBaseUrl":null,"brandDocsUrl":null,"whatItDoes":"Validates JSON-LD structured data and social preview tags (Open Graph, Twitter Card) on up to 10 URLs, returning a grade, score, and prioritized issue list per page.","exampleAgentPrompt":"Check the structured data and social preview tags on these pages — https://example.com/ and https://example.com/about — and tell me what's missing or broken, with a score and grade for each.","exampleUseCases":[{"title":"Pre-launch social sharing audit","prompt":"Before we go live, check whether https://newproduct.com/, https://newproduct.com/features, and https://newproduct.com/pricing have proper Open Graph and Twitter Card tags set up, and let me know the score and any issues for each page."},{"title":"Diagnosing rich snippet failures","prompt":"My blog posts aren't showing rich results in Google — can you check https://myblog.com/post-1 and https://myblog.com/post-2 for JSON-LD structured data problems and tell me what types were found and what's wrong?"},{"title":"Competitor structured data benchmarking","prompt":"Audit the structured data and social tags on https://competitor-a.com/ and https://competitor-b.com/ — I want to see their grades and what schema types they're using compared to what's missing."}],"resultDescription":"A JSON array with one result object per URL, each containing: a letter grade (e.g. B-), a numeric score 0-100, a severity rating, boolean flags for Open Graph and Twitter Card presence, a list of structured data types found (e.g. Organization, Product), and a prioritized list of issues with descriptions.","failureModes":["Invalid or unreachable URL returns an error entry for that URL rather than aborting the whole batch","More than 10 URLs submitted causes a validation error","Pages with no HTML (e.g. PDFs, redirects to binary assets) may return empty structured data findings","Payment failure (insufficient USDC balance) blocks the call entirely with a 402 response","Rate limiting or bot-blocking on the target site may cause incomplete results"],"whenToPreferThis":"Choose this endpoint when you specifically need to audit JSON-LD structured data, Open Graph, and Twitter Card tags — it returns a clean grade, score, and worst-first issue list per page in one call, with no API key or account required.
