# Get rates

> Returns the effective per-use rates for the authenticated tenant, including regional pricing adjustments.

```http theme={null}
GET /v1/billing/rates
```

Returns your tenant's effective rate card, including per-use prices for minting and verification. If your organization has a custom rate card assigned by a platform admin, those rates are reflected here. Otherwise, the default rate card applies.

Rates are automatically adjusted for your region based on your organization's country.

    ## Base URLs

    - **Production**: `https://api.truthlocks.com`

    - **Sandbox**: `https://sandbox-api.truthlocks.com`


    ## Authentication

    - **API Keys**: Use `X-API-Key` header for machine-to-machine operations

    - **Bearer Tokens**: Use `Authorization: Bearer <jwt>` for user-initiated
    operations


    ## Tenant Identity

    In production, tenant identity is derived from the authenticated context
    (API key or JWT).

    The `X-Tenant-ID` header is ignored in production to prevent spoofing.
