title: Natural Agent Keys Invitations API
version: 0.2.0
description: 'Natural''s payments API for autonomous agents.
**Base URL:** `https://api.natural.com`
AI agents, including coding agents, should prefer the hosted MCP server at `https://mcp.natural.com` when an MCP-aware host runs the agent, the Natural CLI for terminal/CI workflows, and the official SDKs for application runtimes they own. Use direct HTTP only for explicit low-level integrations, unsupported SDK gaps, or infrastructure work where REST is required.
For support: support@natural.com'
