Web Search Research x402 offerings

Web page to Markdown: fetch a public URL and get clean Markdown plus structured JSON (title, meta description, language, headings, tables, links, Open Graph, JSON-LD). Deterministic, no AI, fast. Res…

Search the global corpus of published fact-checks (ClaimReview) by free-text claim. Returns matching claims with the claimant, claim date, and each fact-check review's verdict (textualRating, e.g. "False", "Misleading", "True"), the publisher (PolitiFact, Snopes, FactCheck.org, Reuters Fact Check, AFP, …), the review URL, and review date. Covers every topic — politics, health, science, viral and misinformation claims. Optional language, recency (maxAgeDays), and publisher-site filters. Aggregated by Google from publishers' schema.org ClaimReview data. Use it to check whether a claim has been independently fact-checked and how it was rated, rather than asserting from training data.

Fetch any URL and extract structured page metadata: title, description, og:image, canonical, favicon, site name, author, published time, language, and the first ~500 chars of body text. SSRF-guarded against private networks. 8s timeout, 512 KB max body. Returns the parsed metadata plus the raw og:/twitter:/itemprop meta dictionary for inspection.

Render a URL in a real headless browser (JavaScript executed) and return its article content with the clutter stripped — same cleaning + output formats as /api/url/clean, but for client-rendered / SPA pages whose content only appears after JS runs (where a raw HTTP fetch returns an empty shell). `format`: markdown (default), text, both (JSON envelope), html (self-contained reader page, raw text/html), or pdf (typeset reading doc, raw application/pdf). Optional `waitUntil` (load|domcontentloaded|networkidle0|networkidle2, default networkidle2) and `timeoutMs` (1000-15000, default 12000) control how long to let JS settle. Use /api/url/clean instead for server-rendered pages — it is faster and cheaper; only reach for render when JS rendering is required.

Fetch any URL and return its article content with the clutter stripped — nav, ads, sidebars, footers, scripts, styles, comments removed via heuristic extraction (<article> / <main> / role=main / densest block). Choose the output with `format`: markdown (default), text, both (JSON envelope), html (a self-contained readable reader-view page, raw text/html), or pdf (a clean typeset reading document, raw application/pdf). html/pdf are built from the same cleaned content, so they carry no live page, no third-party assets, no trackers. SSRF-guarded, 512KB body cap, 8s timeout, 5 redirects max. JSON formats return { url, finalUrl, title, markdown?, text?, wordCount, sourceBytes }. This uses a raw HTTP fetch (no JavaScript) — for client-rendered / SPA pages whose content only appears after JS runs, use /api/url/render (same formats, headless-rendered). For a pixel-perfect image of the live page use /api/ai/screenshot; to enumerate a page or sitemap into its links use /api/url/map.

Discover the URLs a page or sitemap points at in a single fetch. Point it at an XML sitemap or sitemap-index and it returns the <loc> URLs; point it at an HTML page and it returns the <a href> links — auto-detected. URLs are resolved to absolute, de-duplicated, fragment-stripped, and http(s)-only. `limit` (1-2000, default 200) caps the count; `sameHostOnly` keeps only links on the same host. Single SSRF-guarded fetch, no JavaScript, stateless — NOT a recursive crawler: to go deeper, call map again on a child sitemap or a discovered page. Returns { url, finalUrl, source: "sitemap"|"links", count, capped, urls }.

Fetch a Wikipedia article summary in any of 30 supported languages. Returns title, displayTitle, lang, pageId, description, extract (plain text), extractHtml, lead image, canonical URLs, last-modified timestamp, word count, license, and an attribution string. Backed by https://<lang>.wikipedia.org/api/rest_v1/page/summary. Content is CC BY-SA 4.0 with attribution provided.

Live news search. Returns recent headlines with title, URL, snippet, publisher source, relative age, and a breaking-news flag — real-time coverage past any model training cutoff. Supports count (1-20), offset, country (2-letter), and freshness (pd=past day, pw=past week, pm=past month, py=past year). Use for current events, market-moving developments, monitoring, and "what happened with X" questions. For general web results see /api/search/web; for Hacker News specifically see /api/news/hn-top.

Is this claim true? Fact-check a single factual claim or statement against live web evidence before your agent relies on it. A fact-checking oracle, hallucination guard, and grounding and citation check for misinformation review: returns a verdict (supported / contradicted / insufficient), a confidence score, and source citations, as a signed attestation your agent can cite.

Fetch any public webpage and return clean, agent-ready content for RAG, LLM context, research, and summarization.
