# Integrate any API (secrets + agent)

> Connect third-party APIs in Mythex by storing keys as secrets and asking the agent to wire the client — no connector catalog.

# Integrate any API (secrets + agent)

Mythex does **not** ship a connector catalog. You integrate external APIs the same way a developer would: **store keys as secrets**, ask the agent to call the API from your app.

## Steps

1. Open the provider’s docs and create an API key
2. Add it under **project settings → Secrets** (or wait for a [secrets request card](/features/secrets-in-chat))
3. Prompt, for example:

```text theme={null}
Integrate the [SERVICE] API using the secret [ENV_NAME].
Call [ENDPOINT] from the server side. Never expose the secret to the browser.
Show a simple UI that displays the result.
```

4. Confirm Preview, then [publish](/publish/how-to-publish) if needed

## Tips

* Prefer server-side routes for secret keys
* Name env vars clearly (`RESEND_API_KEY`, not `KEY`)
* After changing secrets on a live app, publish again
