Fetch a web page and extract a specific piece of information from it using AI. Param: url, query. It is built for autonomous AI agents: discover it, pay for it, and consume it in a single request via the x402 protocol — no API key, no account.
GET https://x402render.vercel.app/extract
Example: /extract?url=https://example.com&query=the main heading
url | string — http(s) URL (required) |
query | string — what to extract, e.g. the price (required) |
The endpoint returns HTTP 402 Payment Required with the price, asset (USDC), network (Base / eip155:8453), and pay-to address. Your agent pays on-chain and resends with the payment proof header. Compatible with @coinbase/x402 and @piprail/sdk.
