About

Fix or hand-configure an existing ElevenLabs API key. Use when a key stopped working (401 or invalid_api_key), when an administrator issued the key, when the user's role cannot create keys, or when the user already has a key and needs it in the right place. Checks whether ELEVENLABS_API_KEY is configured and valid, without reading it into the conversation. Not for first-time setup or adding ElevenLabs to a project (use onboarding).

Use cases: backend, identity-access

# ElevenLabs API Key Setup

For a key the user already has, or one that stopped working. For adding
ElevenLabs to a project from scratch, use the `onboarding` skill.

**A key the user already has (for example from an administrator):** don't
sign in for a new one. Tell them to paste it after `ELEVENLABS_API_KEY=` in
the env file of the app that uses it (`.env.local`, or `.env` in a Python
project), never into this chat, and to tell you when it's done. Then check it
(if `check` finds no key, or ElevenLabs rejects it, and offers to sign in,
ask the user to check the paste instead of signing in):

```bash
npx -y @elevenlabs/cli@latest onboard check
```

**A key that stopped working:** run the same command from the app's folder.
It finds the key the app would use (the shell, the env file, or a `.env` up
the tree), checks it with ElevenLabs without printing it, and prints JSON:
`next` is the step (spelled out in `instruction`; where the list below differs,
follow the list), `run` the exact command, and `say` what to tell the user (tell
them as written). Follow it until the key works; for a rejected key it
signs the user in for a new one. What each `next` means:

- `run`: run `run`. `wait`: show `say`, then run `run` again right away.
- `ask_user`, or a `fix` that needs the user's shell or secrets: ask them
  what `say` says, wait for their answer, then run `run`, unless they said no.
- `write_code`: if the app already reads `ELEVENLABS_API_KEY` (through the
  SDK or its own requests), don't change its code: after `connect`, run
  `run`; after `check`, tell the user the key works (not `say`) and stop.
  Otherwise make sure the code uses the SDK, then run `run`; if nothing
  shows what the app should do with ElevenLabs, ask the user first, and don't
  pick a product for them.
- `offer_test`: ask the question in `say`; run `run` only if they say yes.
- `done`: tell the user `say`.

## Rules

- Never open, print or `cat` the env file, and never echo
  `ELEVENLABS_API_KEY`; `onboard check` verifies the key for you.
- Never ask for an API key in chat, and never accept one pasted there. If one
  appears, tell the user to rotate it on the API keys page.
- Never put the key in code; the SDK reads `ELEVENLABS_API_KEY`.
- Don't run the app (or its start script) or make speech to try it until the
  user says yes. API calls that what they asked for needs, like creating an
  agent, are fine. Once the code is written, run `onboard check` before you
  finish: it verifies the key and the code.
- For browser or client-side apps, keep the key on the server and issue
  short-lived tokens where the product supports them.

## No npx

If `npx` isn't available (Node.js isn't installed), install the CLI (or
update it if it's already installed: `brew upgrade elevenlabs`, or run the
installer again), then run `elevenlabs onboard check` instead:

- macOS or Linux: `brew install elevenlabs/tap/elevenlabs`, or
  `curl --proto '=https' --tlsv1.2 -LsSf https://github.com/elevenlabs/cli/releases/latest/download/elevenlabs-cli-installer.sh | sh`
- Windows: `powershell -ExecutionPolicy ByPass -c "irm https://github.com/elevenlabs/cli/releases/latest/download/elevenlabs-cli-installer.ps1 | iex"`

If `elevenlabs` isn't found after the installer ran, use
`~/.cargo/bin/elevenlabs` in its place, here and in every `run` the CLI gives.
