Two ways to use Natural. Pick the tab that matches you.

<Tabs>
  <Tab title="AI assistant">
    You're an AI host (Codex, Cursor, Claude Code, or another MCP-aware agent) operating Natural for
    a user. They describe payments in plain English; you connect Natural's hosted MCP server and call
    Natural's tools — no API key needed.

    ### Read the playbook

    Have the user paste this into their agent:

    ```text theme={null}
    Read https://www.natural.co/skill.md and set up Natural for me.
    ```

    `skill.md` is the full setup guide: it installs Natural's hosted MCP server, runs browser OAuth,
    and tells the user when to approve the authorization page. For host-specific details (Codex,
    Cursor, Claude Code), see the [MCP guide](/guides/platform/mcp).

    ### Sign up and verify

    The user signs up at [natural.co/signup](https://natural.co/signup) and completes **KYB** in the
    [dashboard](/guides/platform/dashboard). OAuth uses their logged-in Natural session.

    ### Make your first payment

    Walk through [Create a payment](/guides/create-payment) or
    [Request a payment](/guides/request-payment) — each has MCP examples.
  </Tab>

  <Tab title="Application developer">
    You're writing software that uses Natural: a backend, a SaaS, an agent runtime, a CI script.

    ### Sign up and get a key

    Sign up at [natural.co/signup](https://natural.co/signup), complete KYB, and generate an API key
    from the [dashboard](/guides/platform/dashboard).

    ### Install for your runtime

    <CodeGroup>
      ```bash Python theme={null}
      pip install naturalpay
      ```

      ```bash TypeScript / Node theme={null}
      npm install @naturalpay/sdk
      ```

      ```bash Terminal / CI theme={null}
      curl -fsSL https://natural.co/install.sh | bash
      ```
    </CodeGroup>

    No SDK for your language? Use the [REST API](/guides/platform/apis) at `api.natural.co`.

    ### Make your first payment

    Walk through the [Create a payment guide](/guides/create-payment) end to end.
