You only pay for results
Credit is held when a job starts and charged only when it succeeds. Failures, timeouts and content-policy blocks are released back to your balance automatically.
Drop-in compatible
One simple JSON endpoint for every model, plus an OpenAI-compatible /v1/images/generations. Existing OpenAI image code only needs a new base URL and key.
Blocking, streaming or async
Wait for the image in one call, stream progress as server-sent events, or submit and poll. Your choice per request.
Keys with spending limits
Create a key per app or per customer, cap what each can spend, and revoke one without touching the others.
Every request logged
See each generation with its model, cost, status and output in your dashboard, and your spend by day and by model.
Your files, on a fast CDN
Outputs are served from our edge storage for 7 days, long enough to download them into your own storage.
Questions
How does billing work?
You add credit by card from $5. Each successful image or second of video is deducted at the listed price. There is no subscription and no monthly minimum.
What happens if a generation fails?
You are not charged. The credit reserved for it returns to your balance as soon as the failure is known.
Can I use it from my existing code?
Yes. If you use the OpenAI SDK, point base_url at https://api.xelentapi.com/v1 and call images.generate.
What content is allowed?
Everything our acceptable use policy allows. Requests are moderated, and accounts that repeatedly try to generate prohibited content are closed.
