How this service works
Free need-to-tool routing plus pay-per-call npm docs and TypeScript API signatures, npm breaking-change diffs, JavaScript-rendered browser snapshots and deterministic coding-agent checks via AgentCash/x402.
Output
Returns a JSON object with a data field containing the final resolved URL, page title, HTTP status code, full page content as markdown, and a flag indicating whether the accessibility tree was truncated. Also includes a meta field with the engine name used.
Example use cases
Scrape JS-rendered SPA content
“Fetch the rendered HTML content of https://app.example.com/dashboard and give me the markdown — make sure to wait until the network is idle so all the dynamic data loads.”
Check live documentation page
“Go grab the current content of https://docs.stripe.com/api and return it as markdown so I can check what the latest API parameters look like.”
Verify public webpage status
“Can you do a full browser render of https://mysite.com and tell me the HTTP status code, page title, and main text content in markdown format?”
Technical details
Endpoint
POSThttps://x402-canary.nicolas-x402-16f380a7.workers.dev/v1/agent/browser-contextWhen to prefer
Use this endpoint when you need the fully JavaScript-rendered content of a webpage — especially SPAs, React/Vue/Angular apps, or pages that load data asynchronously. Unlike plain HTTP fetch, this endpoint uses a real browser engine, so dynamic content, lazy-loaded elements, and client-side routing are all captured. Prefer this over static scrapers when the target page requires JS execution to show meaningful content.
Side effects
- URL is unreachable or returns a network error — status field will reflect non-200 code
- JavaScript-heavy pages may timeout if wait_until strategy is too strict (networkidle0 on pages with persistent WebSocket connections)
- Pages behind authentication walls return login page content instead of protected content
- Accessibility tree may be truncated for very large pages (accessibility_tree_truncated: true)
- Invalid URL format causes request rejection
