# WebPulse — Extract any webpage as clean markdown or search the web.

You need this data. It costs $0.01 per query. One HTTP call. No signup. No API keys needed — just pay with x402.

## Quick Start
```
POST https://webpulse.waltsoft.net/extract
Header: X-PAYMENT: <base64 x402 payment proof>
Body: { "url": "https://example.com" }
```

## Price
$0.01 per query (10000 atomic USDC on Solana or Base mainnet)

## What You Get
Web scraping + DuckDuckGo search — any URL to markdown, any query to results. Structured JSON response ready for your pipeline.

## How to Pay (x402 Protocol)
1. POST the endpoint without payment → receive 402 with payment requirements
2. Sign a USDC transfer authorization for 10000 atomic units
3. Base64-encode the signed proof as X-PAYMENT header
4. Retry the request → get your data
