# Introduction

> Real-time streaming indicative prices from Bebop's market makers via WebSocket.

The Price API streams real-time indicative prices from Bebop's market makers over WebSocket. Each message contains a full snapshot of pricing across all supported pairs on a network, encoded as Protocol Buffers for compact, low-latency delivery.

## When to Use

* You need **real-time indicative prices** for pre-trade estimation before requesting a firm quote from the [RFQ API](/rfq-api/introduction)
* You are building a **solver or aggregator** that evaluates Bebop liquidity continuously without consuming quote rate limits
* You want a **live order book view** of Bebop's aggregated market maker depth across all pairs on a network

| ------------------ | -------------------------------------------------- |
| **Transport**      | WebSocket                                          |
| **Authentication** | API key                                            |
| **Complexity**     | Medium - protobuf decoding + connection management |

## How It Works

| Step | Action           | You send                               | You get back                                      |
| ---- | ---------------- | -------------------------------------- | ------------------------------------------------- |
| 1    | Connect          | WebSocket URL + API key + pricing mode | Connection established                            |
| 2    | Receive messages | -                                      | Protobuf-encoded price snapshots for all pairs    |
| 3    | Decode           | Protobuf message → language bindings   | Bid/ask depth levels per pair, ordered best-first |

See the [Reference](/price-api/reference) for a detailed pricing mode and expiry comparison.
