Pay-per-call agent APIs over x402 (USDC on Base): per-token LLM inference (Llama 3.1/Qwen/Mistral), per-second GPU/CPU compute, on-chain/DeFi + SEC-EDGAR + news data, and clean-Markdown/Cloudflare-stealth web scraping. Signed receipts, no signup — auto-claims a free-tier key. Install via npx -y gate402-mcp.
