Technical details
Endpoint
GEThttps://ged-x402-browser.jvalamis.workers.dev/v1/browser/jsonWhen to prefer
Choose this endpoint when you need to extract structured data from a live webpage or raw HTML using a natural-language prompt without managing API keys — especially when the page requires JavaScript rendering. It is ideal for one-off AI-powered extractions paid per-call with USDC on Base, Polygon, Arbitrum, World, or Solana, bypassing traditional API key authentication entirely.
Side effects
- URL is unreachable or times out — empty or error response
- Page requires authentication or bot detection blocks rendering — incomplete extraction
- Prompt is too vague — AI returns unexpected or empty fields
- response_format schema conflicts with extractable content — partial or null fields
- Payment on-chain fails or USDC balance insufficient — 402 payment required error
- Invalid URL format — request rejected before browser launch
