# API Endpoints Overview

The **API Endpoints** section lists every REST endpoint in the Fireblocks API. Each endpoint page includes:

* **Description** — What the endpoint does and when to use it
* **Parameters and request body** — Required and optional fields
* **Response schema** — Response shape and status codes
* **Playground** — Try the request with your credentials (when enabled)

The reference is generated from our [OpenAPI 3.0 specification](https://swagger.fireblocks.com/openapi.yaml). You can import the spec into Swagger UI, ReDoc, Postman, or use it to generate client libraries.

## Before you call the API

* **[Authentication](/reference/signing-a-request-jwt-structure)** — Sign requests with JWT using your API key and secret
* **[Rate limiting](/reference/rate-limiting)** — Request limits and best practices

## Testing your calls

Each endpoint page has a **playground** where you can try requests with your credentials. If you prefer to test from Postman instead, use the [Postman Guide](/reference/explore-postman-collection).

## Next steps

Use the sidebar to browse endpoints by category, or search for a specific operation. For high-level concepts and SDKs, see the [API Overview](/reference/api-overview).
