# x402-web-extract: web scraping, prices, balances, YouTube

> Pay-per-call API for AI agents on Base mainnet (USDC via CDP x402 facilitator). Five endpoints: /fetch returns clean markdown or JSON from any public URL, /price returns real-time USDC spot prices for EVM tokens, /balance returns native + USDC balances for any EVM wallet, /youtube-video resolves a YouTube video to a direct MP4 download URL, /youtube-audio resolves a YouTube video to an audio-only stream URL. Each call returns HTTP 402 with an exact payment requirement; agents pay automatically via x402. No API keys, no accounts.
