Setup

  1. Create an ElevenLabs account: Go to https://elevenlabs.io and sign up or sign in. The free tier includes a monthly character allowance suitable for testing.
  2. Create an API key: Open https://elevenlabs.io/app/settings/api-keys and click ‘Create API Key’. You can restrict the key to specific permissions (e.g. text-to-speech, voices read).
  3. Store the key: Copy the key and add it to your .env file as ELEVENLABS_API_KEY=…
  4. Verify access: Run the Get Subscription tool to confirm the key works and see your character quota.

Provider notes

  • Authentication uses the xi-api-key header, not Authorization
  • Text to Speech returns raw binary audio (application/octet-stream), not JSON - treat the response as a file
  • Speech synthesis consumes characters from your plan quota; overages depend on your subscription tier
