# Exa

> Neural web search, page contents, similar-link discovery, and grounded answers via the Exa API

## At a glance

* **Availability**: Experimental ([how to enable](/cloud/integrations)).
* **Auth**: API key.
* **Connection**: The key from `EXA_API_KEY` is sent as the `x-api-key` header.
* **Docs**: [https://docs.exa.ai/reference/getting-started](https://docs.exa.ai/reference/getting-started)

## Credentials

Set these per environment. See [Connect an integration](/cloud/integrations).

| Variable      | Required | Description                                                                               |
| ------------- | -------- | ----------------------------------------------------------------------------------------- |
| `EXA_API_KEY` | Yes      | Exa API key from the Exa dashboard [Docs](https://docs.exa.ai/reference/getting-started). |

## Setup

1. **Create an Exa account**: Go to [https://dashboard.exa.ai](https://dashboard.exa.ai) and sign up - new accounts include free credits for testing.
2. **Create an API key**: Open [https://dashboard.exa.ai/api-keys](https://dashboard.exa.ai/api-keys) and create a key with a descriptive name (e.g. 'Veryfront Integration').
3. **Store the key**: Add it to your .env file as EXA\_API\_KEY=...
4. **Verify access**: Run the Search tool with a simple query. A 401 means the key is invalid; a 402 means you are out of credits.

* All endpoints are billed per request from your credit balance; Answer also incurs LLM generation cost
* Deep search types cost more than fast/instant - use type 'auto' unless you need depth
