Welcome to the Rebar Data API

The Data API provides structured access to Bitcoin-native assets and metaprotocol activity on Bitcoin L1.

Introduction​

The Rebar Data API is a RESTful interface that enables real-time and historical access to metaprotocol data on Bitcoin L1. As Bitcoin DeFi expands atop protocols like Runes and Alkanes, verifiable, accurate data is required for production infrastructure. The Data API preserves L1 security while enabling programmable coordination.

All endpoints require authentication. You can get an API key via Rebar Data.

The following API pages document how to connect to and interact with the Data API.

Getting Started​

To learn how to use these APIs, visit the Rebar Data portal.

Coverage​

The API includes coverage for:

  • Native BTC data: Query confirmed transactions and addresses historically
  • Ordinals: Track inscription metadata, transfer history, sat position, and rarity classification
  • BRC-20s: Query token balances, minting events, transfer logs, and protocol compliance status
  • Runes: Monitor etching events, rune deployment data, and transaction flow across unspent outputs

Endpoints follow consistent schemas and emphasize:

  • Bitcoin-native primitives (txid, vout, scriptPubKey)
  • Indexed metaprotocol overlays (ordinal IDs, rune tickers)
  • MEV-sensitive transaction ordering metadata (mempool timestamps, miner-included position)

Use Cases​

Developers can integrate the API for a range of use cases:

  • Build wallets that visualize Ordinals and BRC-20 balances with accurate UTXO tracking
  • Track mint congestion and rarity volatility for BRC-20 and Runes
  • Simulate MEV opportunities and protection strategies within Alkane contract flows
