Introduction

Welcome to the official documentation for Rebar Data — the unified data access layer for Bitcoin-native protocols, combining a high-level REST API and low-level JSON-RPC service.

Rebar Data is a two-part infrastructure product designed to give developers and miners direct, protocol-aware access to Bitcoin. It consists of:

• Rebar API — a RESTful interface for querying and constructing transactions involving Ordinals, Runes, BRC-20s, and other metaprotocols

• Rebar RPC — a JSON-RPC endpoint fully compatible with Bitcoin Core, optimized for speed, reliability, and miner connectivity

Together, these services abstract Bitcoin’s complexity without compromising its security model — making it easier to build on and interact with the base layer directly.

Why It Matters

The Bitcoin ecosystem is entering a new era of on-chain programmability. Protocols now embed metadata, asset logic, and state transitions directly into Bitcoin’s UTXO model. But native tooling — from Core RPCs to indexers — lacks the context and structure needed to support this evolution. Rebar Data solves this by offering developers and infrastructure operators a complete access layer, tuned for the realities of Bitcoin's new L1 use cases.

Rebar Data Capabilities

The process involves:

• Rebar API:

  • Structured endpoints for protocol-specific data: token balances, inscriptions, Rune state

  • Transaction builder workflows with protocol encoding logic

  • RESTful integration for analytics and application backends

• Rebar RPC:

  • Drop-in Bitcoin Core compatibility via JSON-RPC

  • Enhanced uptime, connection pooling, and mempool visibility

  • Optional private relay paths for sensitive transaction flows

To get started with Rebar Data, you'll need an API key to authenticate requests across both REST and RPC services. The Developer Guide provides everything you need to begin integrating with Bitcoin through Rebar’s infrastructure.
