# GEDX402 Browser Outcome JSON Extractor

> GEDX402 Browser Outcome JSON Extractor is a paid API for AI agents from browser.gedx402.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Renders a URL or raw HTML in a headless browser and extracts structured JSON data according to a provided schema, paying per-call with USDC via x402

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability gedx402-browser-outcome-json-extractor-e7e1acd7
```

Example prompt: Go to https://www.amazon.com/dp/B09XYZ1234 and extract the product name, current price, and availability as structured JSON — use a schema with fields: name (string), price (string), availability (string).

## When to prefer this

Use this endpoint when you need to extract structured, schema-defined data from a live URL or raw HTML, especially for JavaScript-rendered pages that simple HTTP fetchers cannot handle. Prefer it over static scrapers when the target page requires a real browser to load content, and when you want zero-API-key setup with per-call USDC micropayments via x402 on Base, Polygon, Arbitrum, World, or Solana.

## Known failure modes

- URL is unreachable or returns non-200 — extraction returns empty or error object
- JavaScript-heavy page fails to fully render before extraction — waitUntil gotoOptions can mitigate this
- response_format schema not provided — endpoint may return error or unstructured output
- Page blocks headless browsers (bot detection) — may return incomplete data
- USDC payment insufficient or blockchain network unavailable — HTTP 402 payment required error

## How this service works

Schema extract — Firecrawl extract parity: one x402 payment returns structured JSON from a URL using page AI extraction + your response_format schema. POST { url, response_format, prompt? } on browser.gedx402.com → { data }. x402 settlement $0.10. Hero: GET /heroes/schema-extract. Discover: GET /v1/models?bundle=browser.

## Output

Returns a JSON object whose shape matches the provided response_format schema, with fields populated by AI-driven extraction from the rendered page — e.g. {"name":"Example Widget","price":"$29.99","availability":"In stock"}. No API key required; payment is settled automatically via x402 USDC on-chain.
