## Check model capabilities

Open the [model catalog](https://api.xsopc.com/pricing), copy the complete model ID, and check its endpoints, supported inputs, prices and groups. Display names, API IDs and upstream aliases may differ. Use the ID published by this platform.

These guides describe available integration methods. An individual model's access to images, video, streaming, caching or tools depends on its details and your account permissions. An endpoint's existence does not mean every model supports it.

## Configure the address

- Platform: `https://api.xsopc.com`.
- API base URL for common clients: `https://api.xsopc.com/v1`.
- Full chat endpoint: `https://api.xsopc.com/v1/chat/completions`.

Some clients append `/v1` automatically. Follow the client's instructions to avoid `/v1/v1`. Verify a basic cURL request before configuring a third-party application.

## Documentation and live settings

Examples describe request formats, not guaranteed model availability or prices. Models, payment methods, verification options, invoice thresholds and referral rules follow the current console settings. Replace `YOUR_API_KEY` and `YOUR_MODEL_ID` before running examples.
