# Quickstart
> Get an API key and make your first call in under a minute.
## 1. Get a key
Every network gets 3 free guest requests with no key at all, use any placeholder string as the key to try it. For the daily member limit (50 messages/day) and a portable key, visit [`/cli`](https://asklethe.ai/cli) and connect a wallet. You'll get a key that looks like `ltk_…`.
## 2. Point your tool at LETHE
The base URL is drop-in for anything OpenAI- or Anthropic-compatible:
* OpenAI-style: `https://asklethe.ai/v1`
* Anthropic-style: `https://asklethe.ai` (with `ANTHROPIC_BASE_URL`)
```bash cURL theme={null}
curl https://asklethe.ai/v1/chat/completions \
-H "Authorization: Bearer $LETHE_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "lethe",
"messages": [{ "role": "user", "content": "…" }]
}'
```
```ts TypeScript (openai SDK) theme={null}
const client = new OpenAI({
baseURL: "https://asklethe.ai/v1",
apiKey: process.env.LETHE_API_KEY,
});
const res = await client.chat.completions.create({
model: "lethe",
messages: [{ role: "user", content: prompt }],
});
```
```python Python (openai SDK) theme={null}
from openai import OpenAI
client = OpenAI(
base_url="https://asklethe.ai/v1",
api_key="$LETHE_API_KEY",
)
resp = client.chat.completions.create(
model="lethe",
messages=[{"role": "user", "content": prompt}],
)
```
## 3. Pick a model
Use `lethe` for text, `lethe-vision` for image/video input. See [Models](/api-reference/models). Claude Code's default model ids (`opus`, `sonnet`, `haiku`) and any `claude-*` id are automatically aliased to `lethe`, so Claude Code works with zero model-name changes.
