# Voyage AI

> Add a Voyage AI API key under Settings, Model Providers and call Voyage embedding models through the LangWatch AI Gateway.

## Add the credential

Open **Settings > Model Providers**, click **Add Model Provider** and select **Voyage AI**. Give the row a name, pick the organization, team or project it belongs to, and fill in:

| Field            | Value                   |
| ---------------- | ----------------------- |
| `VOYAGE_API_KEY` | Your Voyage AI API key. |

Save the row. Every virtual key whose scope can see the row can now dispatch to it, unless the key restricts its providers. See [Virtual keys](/docs/ai-gateway/virtual-keys#create-a-virtual-key).

## Model names

Write the Voyage model id, for example `voyage-3.5` or `voyage/voyage-3.5`. The gateway strips the `voyage/` prefix before it calls Voyage.

## Send a request

```bash theme={null}
curl https://gateway.langwatch.ai/v1/embeddings \
  -H "Authorization: Bearer $LANGWATCH_VIRTUAL_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "voyage-3.5",
    "input": ["The quick brown fox"]
  }'
```

The gateway sends the request to `https://api.voyageai.com/v1/embeddings` and returns the OpenAI embeddings shape.

## Endpoints

Voyage AI serves `POST /v1/embeddings` only. Any other request to a Voyage row is rejected with the message `voyage credentials only accept embedding requests`.
