What's free
$50 in free credits on signup (no credit card) — speech-to-text
Rate limits
Bounded by the $50 credit; pay-as-you-go afterward (4 concurrent requests or 4 hours of audio/hour)
The catch
No credit card required to start — an explicit $50 developer credit. Commercial terms not stated on the pricing page. Native STT REST API.
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
