Questions

Which model names do I use?

The IDs shown in the catalog, such as the ones in the table above. Each model works on the APIs listed next to it.

Do you store my prompts?

No. We keep usage records (model, token counts, cost and timing), not the text of your prompts or responses. The privacy policy has the details.

Can I get a refund?

Unused paid credit can be refunded within 30 days of payment, as set out in the terms.

Is tax included?

Listed prices exclude tax. Any tax that applies is calculated at checkout based on your location.

What happens when my balance runs out?

Requests are rejected with a clear error until you top up.
