## Example request

The example below calls `glm-5.2` through OpenAI Chat Completions (`/v1/chat/completions`). Point base\_url at `https://api.apiyi.com/v1` — everything else matches the official API.

```bash theme={null}
curl https://api.apiyi.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $APIYI_API_KEY" \
  -d '{
    "model": "glm-5.2",
    "messages": [{"role": "user", "content": "Hello"}]
  }'
```

<Tip>Read the key from an environment variable, never hard-coded. In production, issue separate tokens per use case so you can revoke and attribute usage individually.</Tip>
