# Respan

> Give the Sazabi agent the Respan CLI (respan) in its sandbox to manage LLM observability including traces, prompts, evaluators, experiments, datasets, and coding-agent tracing.

[All Respan integration capabilities](https://docs.sazabi.com/catalogs/integrations/respan)

## About

This CLI connection makes the Respan CLI (`respan`) available in the Sazabi agent's sandbox. The agent can use it for LLM observability — traces, prompts, evaluators, experiments, datasets, and coding-agent tracing. The tool is baked into the sandbox image; connecting it authenticates (or configures the connection for) the already-installed CLI.

## Prerequisites

* A Sazabi project.
* A Respan API key (`RESPAN_API_KEY`). Optionally, a custom Respan base URL (`RESPAN_BASE_URL`) if you are using a self-hosted or regional Respan instance.

## Set up in the dashboard

Configure the sandbox in the dashboard under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).

**Step 1**

### Find Respan in the catalog

In [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis), find Respan under **Browse sandbox CLIs** and choose to connect it.

**Step 2**

### Provide credentials

Enter the required value: `RESPAN_API_KEY` (your Respan API key). Optionally, enter `RESPAN_BASE_URL` if you are pointing the CLI at a non-default Respan instance. Save to store them securely; Sazabi injects them into the sandbox when the agent runs.

## Set up with the CLI

You can also configure the Respan CLI connection with the [Sazabi CLI](https://docs.sazabi.com/reference/cli.md) (installed and authenticated — see [CLI reference](https://docs.sazabi.com/reference/cli/sandbox-clis.md)).

```bash theme={"system"}
sazabi sandbox-clis connect respan --env RESPAN_API_KEY=<your-respan-key>
```

To validate the credentials without saving, run the same command with `test` in place of `connect` (the test command also requires the `--env` flags).

## Verify

Ask the agent, in a thread, to run the `respan` CLI (a read-only or status command) and confirm it returns real output. If the command is not found, the CLI connection may not be enabled; if it runs unauthenticated or cannot connect, recheck the credentials.

## Troubleshooting

**Command not found** — Confirm the Respan CLI connection is enabled for the project under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).

**Authentication or connection fails** — Recheck the credential/connection values under [**Settings > Sandbox CLIs**](https://app.sazabi.com/settings/sandbox-clis).
