Make a request

After installing, call any endpoint — the SDKs read SPEECHIFY_API_KEY from the environment automatically. Not using an SDK? The cURL tab shows the equivalent raw HTTP request.

1
curl -X POST https://api.speechify.ai/v1/audio/speech \
2
     -H "Authorization: Bearer <token>" \
3
     -H "Content-Type: application/json" \
4
     -d '{
5
  "input": "Hello! This is the Speechify text-to-speech API.",
6
  "voice_id": "george",
7
  "audio_format": "mp3",
8
  "model": "simba-english"
9
}'

The SDKs also send a build-date Speechify-Version header by default. Raw HTTP callers should pin the same header explicitly; see API Versioning.

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.
