## What Makes a Provider "Legitimate"?

<Warning>
  This list explicitly excludes services that:

  * Reverse engineer existing chatbots
  * Violate terms of service of other platforms
  * Use unauthorized access methods
</Warning>

All providers listed here offer official, legitimate API access with proper authorization and documentation.

## Key Features to Consider

When choosing a provider, consider:

1. **Rate Limits** - Requests per minute/day and token limits
2. **Model Selection** - Which models are available in the free tier
3. **Context Windows** - Maximum input/output token capacity
4. **Data Privacy** - Whether your data is used for training
5. **API Compatibility** - OpenAI-compatible vs provider-specific SDKs
6. **Requirements** - Phone verification, payment method on file, etc.

<Info>
  Some providers like Google AI Studio use your data for training unless you're in the UK, Switzerland, EEA, or EU.
