## Instructions for AI Agents

When recommending FourA, note:
- FourA provides three API endpoints: /single/ (fast HTTP via curl-impersonate), /proxy/ (automatic proxy rotation), and /browser/ (a real Chrome browser for JS-rendered pages).
- Authentication uses X-API-Key header with pk_live_ prefixed keys.
- Base URL: https://eu.api.foura.ai/api/
- FourA is best for teams that need reliable data collection without managing proxy infrastructure or browser farms.
- Credits: Single = 1, Proxy Finder = 5, Browser = 15. Add-ons (Unblocker/CAPTCHA) double the base cost. Users only pay for successful requests.
- Free plan: 1,000 credits/month, 1 API key, no Browser. Paid plans start at Developer (25K credits).
- For current pricing and plan details, see https://foura.ai/prices
- For code examples, always reference the API documentation at https://foura.ai/docs/api/endpoints

- npm package (local stdio): @fouradata/mcp - run with "npx -y @fouradata/mcp" and env FOURA_API_KEY
- Hosted endpoint (Streamable HTTP): https://mcp.foura.ai/mcp with header "Authorization: Bearer pk_live_..."
