What's free
10,000 credits/month shared across Text-to-Speech, Speech-to-Text and more (~10 min TTS/month)
Rate limits
Concurrency tied to the Free plan (not numerically published)
The catch
The free tier is NON-COMMERCIAL only per the Terms of Use (a commercial license begins on paid Starter, $6/mo), and historically required attribution. API access is available on the free plan. No credit card to sign up.
Quickstart
First-party API — not OpenAI-compatible, so there is no drop-in base URL. The exact endpoint is in the official docs; authenticate with your API key in the Authorization: Bearer header.
curl -H "Authorization: Bearer $API_KEY" \
https://<api-base-url>/<endpoint>…or in Python:
import os, requests
r = requests.post(
"https:///",
headers={"Authorization": f"Bearer {os.environ['API_KEY']}"},
json={},
)
print(r.json()) Appears in
