# Pricing

For full pricing per model see our [dedicated pricing page](https://nano-gpt.com/pricing) with all models listed. We do not charge any minimum fee per query, nor do we charge any fee on deposits.

Pricing examples and model IDs follow the same canonical-ID policy as this documentation: use exact IDs returned by `GET /api/v1/models`, and do not rely on hidden/internal aliases.

If you are (potentially) going to be a large user of our API reach out to us at [support@nano-gpt.com](mailto:support@nano-gpt.com) or our [Discord](https://discord.gg/KaQt8gPG6V) for a discount.

## Look up a recent request charge

[Request Billing](/api-reference/endpoint/request-billing) returns the original
recorded primary charge and token usage using the response's `X-Request-ID` and
the same inference API key. It is available for 24 hours from the charge's
accounting timestamp. The exact cost is a decimal string in USD or XNO; refunds
and separately billed extras are excluded. For aggregate spend and refund
totals, use [Usage](/api-reference/endpoint/usage).
