What's free
10,000 characters/month TTS (~10 minutes) on the Free plan
Rate limits
15 requests per minute
The catch
The free plan includes a commercial license; overage billed at $0.15/1,000 chars. No card stated as required to start. Not OpenAI-compatible.
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
