# FAQ

> Base URL details, streaming, tiers and sign-up questions.

<AccordionGroup>
  <Accordion title="Do I include /v1 in the base URL?">
    For the OpenAI SDK and most OpenAI-compatible tools, yes: `https://api.xhuoapi.ai/v1`. For the Anthropic SDK and Claude Code, no: `https://api.xhuoapi.ai`. A few clients (Chatbox, Cherry Studio) add `/v1` themselves; their [setup guides](https://xhuoapi.ai/en/guides/index.html) say which.
  </Accordion>

  <Accordion title="Is streaming supported?">
    Yes. Set `"stream": true` on `/v1/chat/completions` and read the server-sent events.
  </Accordion>

  <Accordion title="Why do I get 'model not available' for a model that is listed?">
    The model is probably not in your token's tier. Qwen models and image models are only in Standard and Official. Check the [tiers](/en/tiers) page.
  </Accordion>

  <Accordion title="Do I need a Chinese phone number?">
    No. Sign-up needs an email address only.
  </Accordion>

  <Accordion title="Where are my usage and charges?">
    In the console: top-ups and the usage of each request.
