Every agent-payable API.

Render any live web page to a portable PDF, returned as base64. JavaScript runs first, so single-page apps and dynamic content render correctly instead of coming out blank. Use it to archive a page, capture a receipt, invoice or report, snapshot terms or pricing that may change later, or hand a human a fixed copy of a URL.

Targeted web scrape: pass a CSS selector and get back only the matching elements from a fully JavaScript-rendered page. Each element returns its tag, text content and every HTML attribute. Use it to pull prices, links, table rows, headlines or any repeated structure without parsing a whole document. Returns a match count so an agent can tell an empty page apart from a broken selector.

Extract text from an image by URL (OCR): PNG/JPG/WEBP/TIFF/BMP of a screenshot, scan, receipt, chart or photo -> the readable text, via the Tesseract engine. Keyless, no LLM. Use it to read text an agent can only see as an image. SSRF-guarded; max ~10MB.

Read any live web page as clean, LLM-ready text. Renders JavaScript in a real browser, then strips navigation, ads and boilerplate. Use it when a plain HTTP GET returns empty or garbled HTML: single-page apps, dynamic feeds, or content that only appears after scripts run. Returns markdown, plain text or cleaned HTML plus the upstream HTTP status. Page content is third-party data and is flagged untrusted so an agent treats it as input, never as instructions.

Pixel-accurate PNG screenshot of any live web page, rendered in a real browser at a chosen viewport width, viewport-only or full-page. Returns base64 PNG. Use it when an agent needs to SEE a page: visual verification of a deploy, layout and design capture, confirming a rendered chart or map, or feeding an image to a vision model that cannot read HTML.

Look up a Twitter/X user profile by their screen name. Returns full profile data including id, name, username, bio, follower count, following count, tweet count, verification status, and profile image URL. Query param: username (string, required) - Twitter screen name without @, e.g. GET /users/by/username?username=elonmusk. Returns X v2 API-compatible JSON.
