# Lelantos sandboxes

> Run CostGraph workflows and CI jobs in Lelantos sandboxes: the key to create, its permissions, and its limits

Lelantos is an E2B-SDK-compatible sandbox service ("instant, isolated computers on demand") that is reached at the lelantos.ai domain.

The following table shows what CostGraph runs on this provider.

| Workflows | CI runners | Connect with |
| - | - | - |
| Yes | No | Integrations or your own dispatcher |

CI runners: no. AutoPilot compares runners by price, and this provider publishes no sandbox price.

## Connect

Connect Lelantos on Integrations, and CostGraph starts sandboxes in your Lelantos account. You don't run anything yourself.

1. In CostGraph, go to **Integrations > Sandbox > Lelantos**.

2. Enter these fields:

   * **API key** (`LELANTOS_API_KEY`, required): Your Lelantos API key.

3. Click **Connect**.

### Your own dispatcher

To keep the key out of CostGraph or reach a private network, run your own dispatcher instead.
Set `provider` to `lelantos` and the preceding fields as environment variables, as described in [Run your own dispatcher](https://docs.costgraph.ai/costgraph/workflows/managed-sandboxes.md#run-your-own-dispatcher).

## Key and permissions

LELANTOS\_API\_KEY (or E2B\_API\_KEY) is a Lelantos API key (lel\_..., also accepted in the e2b\_... form). Where to create it is not documented on any reachable vendor page.

The provider doesn't document key scopes or roles.

Sources: [lelantos.ai: home](https://lelantos.ai/).

## Limits

* The only vendor statement found, from a search index of the lelantos.ai homepage rather than a direct read: $50 free credits, and a 2 vCPU / 512 MB sandbox at $0.076 per hour billed per second. No lifetime, idle, region or architecture limits could be read from the vendor. ([source](https://lelantos.ai/))
