Create, rotate and restrict keys in the dashboard or with the API keys endpoints; an organization can have two active keys, so you can rotate without downtime. A **full-access** key can call every endpoint in this reference. A **read-only** key can call `GET` endpoints (and create a trading stream token); any other request returns `403 READ_ONLY_KEY`. A key with an IP allowlist returns `403 IP_NOT_ALLOWED` from any other address. Each endpoint lists which keys can call it under **Access**. ```` ## Related topics - [List all billing events](https://docs.hyperprop.com/platform-api/billing-and-invoices/list-all-billing-events.md) - [List billing cycles](https://docs.hyperprop.com/platform-api/billing-and-invoices/list-billing-cycles.md) - [Get all-months billing aggregates](https://docs.hyperprop.com/platform-api/billing-and-invoices/get-all-months-billing-aggregates.md) - [Get daily billing activity](https://docs.hyperprop.com/platform-api/billing-and-invoices/get-daily-billing-activity.md) - [Billing and invoices](https://docs.hyperprop.com/guides/billing-and-invoices.md) This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
