# Data Plans

Use this page to choose the right data plan.

This is a high-level breakdown. For full details, and to manage plans and billing, use the self-service portal: [console.blockscholes.com](https://console.blockscholes.com/products/data-plans).

### Step 1: Choose a plan

#### Core

* **Hourly updates** via [REST API](/data-access/rest-api.md).
* Coverage for **spot, perpetuals, futures, and options**.
* **Index and mark prices**.
* **Volatility data**.
* No WebSocket access.

#### Prime

* Everything in **Core**.
* **Minutely-level data** via REST (where supported).
* **WebSocket access** via [WebSocket API](/data-access/websocket-api.md).
* **Pull oracle & EIP-712 signatures.**

#### Enterprise

* **Live updates**, including **options pricing updates at 200ms**.
* **Real-world assets (RWA)** datasets and feeds.
* **Dedicated 24/7 support**.

{% hint style="info" %}
Plan determines *what* you can access (and at what granularity). Billing period determines *how far back* you can query.
{% endhint %}

### Step 2: Choose a billing period (controls look back access)

Different billing periods allow different access to historical data.

* **Monthly**: **weekly look back**. Great for clients getting started and focused on current data going forward.
* **Quarterly**: **1-year rolling lookback**. Great for clients who want an extended lookback to validate hypotheses.
* **Yearly**: **3-year rolling lookback**. Option to add even more history, all the way back to **2020**, for full-history research.
