• POST /watch — Check whether a URL's content has changed since the last check. Reports changed true/false/null (first check), plus added/removed paragraphs when it has. (0.01 USDC on Base)
• POST /snap — Render any URL in a real headless browser and get back a full-page screenshot (PNG), a PDF, or the JavaScript-rendered HTML. (0.02 USDC on Base)
• POST /batch — Run a mix of read/watch/verify/compare/tables operations (up to 6 weight-units total — read, watch, verify, and tables cost 1 each, compare costs 2) behind a single payment instead of negotiating a separate payment for each one. Priced at a discount vs paying per-item individually. (0.05 USDC on Base)
• POST /rank — Ranked list of the best x402 services for a task category, scored by price, usage volume, and recency. (0.02 USDC on Base)
• POST /tables — Extract every HTML table on a page as structured JSON — headers, row arrays, and (when headers are unique) row objects keyed by header name. Saves hand-parsing pricing tables, spec sheets, and schedules out of raw HTML. (0.01 USDC on Base)
• POST /verify — Check whether a claimed quote or fact actually appears on a URL — a cheap citation/hallucination checker. Returns exact_match, close_match (with confidence + closest passage), or not_found. (0.01 USDC on Base)
• POST /compare — Compare two URLs' content and report what's different — paragraphs unique to each side, word count delta, whether they're identical. (0.02 USDC on Base)
• POST /read — Clean markdown/text extraction from any URL (JS-rendered) — title, byline, excerpt, and readable body content with nav/ads/scripts stripped out. (0.01 USDC on Base)
• POST /structured — Validate a page's JSON-LD structured data and its social preview tags: which schema.org types are present, whether each carries the fields rich results require, whether any JSON-LD block fails to parse, and whether Open Graph and Twitter Card tags are complete. Returns a 0-100 score, a letter grade and a prioritised issue list. (0.01 USDC on Base)
• POST /links — Find broken links on a page: every anchor is resolved, de-duplicated and checked, then reported with its status code, whether it redirected, how long it took, and a severity. Returns a 0-100 score and a letter grade per page. Anchors, mailto: and tel: are excluded because they cannot be broken. (0.02 USDC on Base)
• POST /sitemap — Audit a site's crawlability: whether robots.txt exists, whether it blocks crawlers, which sitemaps it declares, whether those sitemaps parse as valid XML, how many URLs they contain, whether entries carry lastmod dates, and whether a sample of those URLs actually respond. Returns a 0-100 score, a letter grade and a prioritised issue list. (0.02 USDC on Base)
• POST /a11y — Quick WCAG-oriented accessibility scan of a page's markup: images missing alt text, form fields with no accessible label, missing lang or viewport, links with no accessible name, duplicate ids, and skipped heading levels. Returns a 0-100 score, a letter grade and a prioritised issue list. Static analysis, so it reports what is in the HTML and states plainly that contrast and focus order are not checked. (0.01 USDC on Base)
• POST /seo — Audit the on-page SEO fundamentals search engines and social platforms actually read: title and meta-description length, canonical tag, Open Graph and Twitter Card tags, heading structure, robots directives, viewport, and whether robots.txt and sitemap.xml exist. Returns a prioritised plain-English issue list and a 0-100 score, for one URL or a batch. No browser, so it is fast. (0.01 USDC on Base)
• POST /audit — One complete health check for a page, behind a single payment: on-page SEO and meta tags, JSON-LD structured data and social preview tags, and a WCAG accessibility scan -- optionally plus broken links and robots.txt/sitemap crawlability. Returns one overall score, every finding in a single worst-first list, and the full per-check detail. Cheaper and simpler than negotiating five separate payments. (0.05 USDC on Base)
