# Quickstart

> Get approved, configure ThinkFeel, and send your first request.

ThinkFeel is available through the Curve Labs early access beta program.

<Steps>
  <Step title="Request access">
    Fill out the [request access form](https://curvelabs.org/request-api-access) with:

    * Your name and email
    * Company or project name
    * Intended use case and target audience
    * Expected usage volume
    * Desired persona characteristics
  </Step>

  <Step title="Join the onboarding call">
    The Curve Labs team reviews applications, typically within 2-5 days. After approval, the team schedules a 30-minute onboarding call to discuss your use case, craft a custom persona, define persona traits and communication style, whitelist your email for Playground access, and provide your unique `personaId`.
  </Step>

  <Step title="Create API keys">
    After onboarding, create API keys in one of these ways:

    * Use `/keys` in [Playground](https://playground.curvelabs.org) for the browser UI
    * Run `thinkfeel login --persona-id YOUR_THINKFEEL_PERSONA_ID` for CLI setup
    * Use [CLI + Agents](/cli-agents) for local login, profiles, non-interactive setup, and `SKILL.md`
  </Step>
</Steps>

## Install the SDK and CLI

```bash theme={null}
npm i @curvelabs.org/thinkfeel
```

## Send your first request
