REST API

No SDK needed — make direct HTTP calls from any language:

$
curl -X POST https://api.sws.speechify.com/v1/audio/speech \
>
  -H "Authorization: Bearer $SPEECHIFY_API_KEY" \
>
  -H "Content-Type: application/json" \
>
  -d '{
>
    "input": "Hello from the REST API!",
>
    "voice_id": "george",
>
    "audio_format": "mp3"
>
  }'

See the API Reference for all available endpoints.

Environment variables

Both SDKs read the SPEECHIFY_API_KEY environment variable automatically:

$
export SPEECHIFY_API_KEY="your-api-key-here"

You can also pass the key explicitly when creating the client. See the Authentication guide for security best practices.
