Can I get a refund?: Unused credits are refundable within 30 days of purchase. Contact support with your account email and the unused balance goes back to your original payment method.
What are the rate limits?: Fair use, with defaults most workloads never hit. If you run sustained high-volume traffic and need reserved throughput, contact us.
What counts as cached input?: Prompt prefixes the fleet has seen recently — repeated system prompts, shared long context. Cache hits are reported in usage.prompt_tokens_details.cached_tokens and billed at the cached rate automatically. No configuration required.
Is it really GPT-5.5?: Yes. The upstream model identifies itself as gpt-5.5-2026-04-24, and every response is signed with Ed25519 so you can prove it. Check any response on the verify page.
What payment methods do you accept?: Cards, processed by Stripe. Purchases are one-time credit top-ups starting at $5 — nothing recurring is stored against your account.

Priced like infrastructure, because it is.

Buy credits, point your SDK at a new baseURL, ship. Unused credits are refundable for 30 days.
