The examples use `claude-opus-5-5`. Any model ID from [the models page](https://zurelay.com/docs/models) works.

## Set it up

1. Send your key as a Bearer token in the `Authorization` header.
2. Use Chat Completions for any model, or the Messages API for Claude models.
3. Image models take the same key at `/v1/images/generations`.

## Configuration

**Chat Completions** (`terminal`):

```bash
curl https://api.zurelay.com/v1/chat/completions \
  -H "Authorization: Bearer $ZURELAY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-opus-5-5",
    "messages": [{ "role": "user", "content": "Hello" }]
  }'
```

**Messages** (`terminal`):

```bash
curl https://api.zurelay.com/v1/messages \
  -H "Authorization: Bearer $ZURELAY_API_KEY" \
  -H "anthropic-version: 2023-06-01" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-opus-5-5",
    "max_tokens": 1024,
    "messages": [{ "role": "user", "content": "Hello" }]
  }'
```

**Images** (`terminal`):

```bash
curl https://api.zurelay.com/v1/images/generations \
  -H "Authorization: Bearer $ZURELAY_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "nano-banana-pro",
    "prompt": "A glass prism splitting white light into a rainbow",
    "n": 1
  }'
```
