What's free
Free hosted image models (Flux, Turbo, Stable Diffusion) via a simple GET URL; also text and audio. No signup required to start
Rate limits
Anonymous ~1 request / 15s; free registration (Seed tier) ~1 request / 5s
The catch
Anonymous free images may carry a watermark (since 2025); free registration removes it via the nologo parameter. No card, no phone. Commercial use is not explicitly guaranteed in the docs.

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
