batch
Process many URLs in ONE call. Costs N credits — one per URL in the list after the list is known; failed URLs (ok: false) are refunded. Default mode "read-and-score" is still N, not 2N. Give either "urls" (an explicit list, up to 50) or "site" (a base URL whose pages are auto-discovered via sitemap). "mode" picks what to do per URL: "read" (Markdown), "read-and-score" (Markdown + AIO trust score, default), or "extract" (JSON-LD + OpenGraph + meta + score). Use this for full-site reads or bulk URL processing.
extract_data
Extract the structured data a page already declares — JSON-LD (schema.org), OpenGraph cards, and meta tags — plus the AIO trust score. Deterministic, no AI: returns only data present in the page. Use for fast, reliable facts (prices, products, articles) when the site publishes structured data.
map_site
Discover a site's URLs (from sitemap.xml, falling back to on-page links) without reading them. Fast and cheap — use it to plan which pages to read or crawl next.
read_and_score
Read any URL and return both clean Markdown AND the AIO accuracy score in one call. The recommended default for most AI workflows — gives both content and quality assessment together, so the AI agent can decide how much to trust the content.
read_url
Read any URL and return clean, agent-ready Markdown. Strips HTML noise, preserves semantic content, and returns content optimized for AI consumption. Use this when you need to extract content from a website for an AI agent to process.
score_url
Get the AIO (AI-readability) score for any URL. Returns a 0-100 score plus a list of penalties, benefits, and recommendations describing why the source is or is not well-suited for AI consumption. Use this to evaluate source quality before relying on it.
