After signing up, every developer is assigned a personal API access key, a unique combination of letters and digits provided to access to our API endpoint. To authenticate with the 11Labs Multilingual Text to Speech API simply include your bearer token in the Authorization header.
| Header | Description |
|---|---|
Authorization

Required
Should be Bearer access_key. See "Your API Access Key" above when you are subscribed.

No long-term commitment. Upgrade, downgrade, or cancel anytime. Free Trial includes up to 50 requests.
Convert up to 1,000 characters of text into natural speech in one call and get an MP3 download link. Multilingual v2, Flash v2.5 and Turbo v2.5 voice models, many languages.
Send the text with a voice id and a model id. The request waits until the audio is ready, usually 10 to 40 seconds, and returns a link to the finished MP3 file.
Up to 1,000 characters per call. For longer scripts, split the text at sentence boundaries and send several calls.
Any public voice from the voice library. Use Search Voices to find voices by name, language, gender, age or accent, then pass the voice id as voiceId. Cloned and private voices are not supported.
Every language the chosen model supports. The language is detected from the text, or you can set it with settings.language using an ISO 639-1 code such as en, es or de.
The audioUrl works for 7 days and needs no API key, so you can give it directly to a browser, an audio player or another service. Download the file if you need to keep it longer.
The audio was not ready within about 50 seconds. The response has an id: call Get Speech Result with that id a few seconds later to get the same response with the MP3 link.
Errors such as a text over 1,000 characters, an unknown voice or a refused text return an error code instead of 200, and you can fix the request and send it again.
Multilingual v2 (eleven_multilingual_v2), Flash v2.5 (eleven_flash_v2_5) and Turbo v2.5 (eleven_turbo_v2_5). Eleven v3, v4 and v4 Turbo are in our separate API "11Labs Expressive Text to Speech API".
To obtain your API key, first sign in to your account and navigate to the API you want to use. From the API's Pricing section, choose a plan and complete the subscription process. Once subscribed, return to the API page and you will see your API Access Key displayed at the top of the documentation page. You can use this key to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
The free trial lasts for 7 days and allows you to make up to 50 API requests.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes. If the API offers a free trial, you will see a "Free 7-Day Trial" option in its Pricing section. The trial lasts for 7 days and allows up to 50 API requests, enabling you to evaluate the API before subscribing to a paid plan.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
You can monitor your API usage through the response headers included with every request:
x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.
Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.
Please note that upgrades, downgrades, and cancellations take effect immediately. Once your subscription is canceled, access to the service will end immediately, regardless of any remaining API calls in your quota.
