## Pricing and access

CheapAIAPI is a prepaid, usage-based API with no monthly or annual subscription.
The public catalog contains real starting prices for new customers. Customers
with existing production volume may qualify for lower account-specific rates by
sending the exact model, current monthly usage, and average and peak RPS through
[CheapAIAPI contact](https://cheapaiapi.org/contact).

## Authentication

Send the issued API key as `Authorization: Bearer sk_cheap_...`. API keys are issued after account approval.

## Recommended generation flow

1. Call `GET /v1/models` to discover the SKUs and prices enabled for the account.
2. Submit a generation request with a stable `Idempotency-Key`.
3. Store the returned job `id`.
4. Treat `queued` and `running` as pending, then poll the documented job endpoint or use a signed terminal webhook.
