Fetch a public web page (static HTML, no JS) and convert it to clean Markdown for LLM/agent consumption. Max 2MB.
Scrape web content via a paid X402 API endpoint.
Fetch one public web page and return its readable content as clean text or markdown, with JavaScript executed, so the result reads like the page a human sees. The retrieval half of research: pair it with /search to go from a query to grounded page text. Returns the content, its length, the final URL and the HTTP status. Truncate with max_chars.
Ranked news brief for any topic, refreshed every 15 minutes: the most-corroborated recent headlines, each with source, URL, published time, age in minutes and an importance score computed from how many independent news engines surfaced it and how fresh it is. Zero-LLM, deterministic, no API key. Use it for a market or crypto morning brief, monitoring a company or keyword, or grounding a summary in dated sources.
Real-time web search (via Exa) — ranked results with title, URL, published date, author, and relevance score for a query
Web search with the page text already extracted: one call returns the top results for a query AND the readable content of each result page (JavaScript rendered, markdown or text, truncated to max_chars). What an agent needs to answer a question with sources without a second round of fetches. Up to 5 pages per call, fetched in parallel. Prepaid 10 call pack with 10 percent extra credit: bundle endpoint on this host, pack=contents10.
Web search that returns structured SERP results as JSON. Runs on a dedicated SearXNG instance aggregating multiple engines, so there is no per-engine API key, quota or HTML scraping to manage. Each result carries title, URL, snippet, the source engine and a published date where available. Choose general web, news, or image results, up to 10 per call. Use it to ground an answer in current web sources, research a topic, or monitor news on a query.

Compress long AI-agent context into a concise summary, facts, or episodic memory while preserving key entities.

Can I get just the article, as Markdown you can paste? Pass one URL and get the body back as clean Markdown — headings, paragraphs, lists, fenced code, inline code, links, images, quotes and tables kept; navigation, cookie banners, ads, sidebars, share buttons and the footer dropped. The response is text/markdown itself, so it is ready to paste into a prompt, a document or a file: no wrapper to unwrap. The page is fetched once per paid call, after payment, with a 5-second timeout and at most 3 redirects, and internal, private or link-local hosts, non-web ports, URLs over 2048 characters and URLs that embed credentials are refused with 400 before payment. Calling the same URL again within a minute is served from this service's short-lived cache. One GET, one article, one delivery. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
Market headlines from public RSS in one GET: title, URL, publication time and source, newest first, with nothing older than 48 hours. curl: GET /news?topic=markets&limit=20 (topic markets|crypto|tech|world, default markets; limit 1-50, default 20). Response: {"topic":"markets","count":20,"freshness":{"max_age_hours":48,"newest_published_at":"2026-10-16T20:36:00.000Z","oldest_published_at":"2026-10-16T02:12:00.000Z","fetched_at":"2026-10-16T20:41:07.000Z","items_within_window":94,"dropped_older_than_window":12,"dropped_undated":0},"items":[{"title":"Stocks close at a record as earnings beat","url":"https://…","published_at":"2026-10-16T20:30:00.000Z","source":"MarketWatch","age_minutes":11}],"sources":[{"source":"BBC Business","feed_url":"…","ok":true,"http_status":200,"items_in_window":28,"latency_ms":180}]}. The five market feeds are read in parallel at the moment of the call, each with a 6 second cutoff, and every item carries the time its feed published it, so the age of each headline is visible. 0.005 USDC, no account, no key, one GET, one delivery. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
