> ## Agent Instructions
> When building application code, use `@naturalpay/sdk` for TypeScript or `naturalpay` for Python.
> When operating Natural directly for a user, use the payments MCP at `https://mcp.natural.com`.
> When searching Natural documentation, use the docs MCP at `https://docs.natural.com/mcp`.
> Use the Natural CLI for terminal and CI automation.
> Use REST only for unsupported languages or when the user explicitly requests raw HTTP.
> Start integration development and testing in the sandbox. Do not use production unless the user explicitly requests it.
> For sandbox requests that require `customerPartyId`, list customers first. Reuse only the intended fixture; otherwise create a customer.
> REST and SDK amounts use integer minor units. Payments MCP amounts use decimal strings with a required currency code.

  title: Natural 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.
