Authentication

All Resemble API endpoints use the same authentication method. Your API key works across both servers.

Getting Your API Key

Create or retrieve your API key from the Account → API page.

Authentication Format

All requests require a Bearer token in the Authorization header:

1
Authorization: Bearer YOUR_API_KEY

Servers

Resemble uses two servers depending on the endpoint type:

Synthesis Server Example

$
curl --request POST "https://f.cluster.resemble.ai/synthesize" \
>
  -H "Authorization: Bearer YOUR_API_KEY" \
>
  -H "Content-Type: application/json" \
>
  --data '{
>
    "voice_uuid": "YOUR_VOICE_UUID",
>
    "data": "Hello from Resemble!"
>
  }'

API Server Example

$
curl 'https://app.resemble.ai/api/v2/voices' \
>
  -H 'Authorization: Bearer YOUR_API_KEY'

SDK Configuration

The SDKs handle authentication automatically once you set your API key:

Node.js

1
import { Resemble } from "@resemble/node";
2
3
Resemble.setApiKey("YOUR_API_KEY");

Python

1
from resemble import Resemble
2
3
Resemble.api_key("YOUR_API_KEY")

Store tokens securely and rotate them according to your security policies.
