RPC

The Rebar Labs JSON‑RPC endpoint gives developers deterministic, low‑latency access to Bitcoin L1 data and the execution layer that powers Rebar’s metaprotocol infrastructure.

What You Can Do 🚀

Capability	Description
Chain-Level Reads	Retrieve blocks, transactions, and mempool entries by txid, outpoint, or script, with full fidelity to on‑chain data.
Execution Introspection	Dry‑run transactions, inspect metaprotocol state, and query protocol‑level transaction flows before they hit the mempool.
Indexed Overlays	Access augmented metadata keyed to native Bitcoin primitives—ideal for wallets, analytics, or monitoring pipelines.
Event Polling	Subscribe or poll for state changes with millisecond‑grade latency; perfect for trading bots and alerting systems.

Developer Integration

• Predictable Interfaces – Standard Bitcoin Core method signatures coexist with extended calls for metaprotocol state and simulation.

• Composable Primitives – Work directly with raw chain identifiers; no opaque abstractions.

• Deterministic Responses – Stable, versioned schemas ensure upgrades never break existing clients.

Authentication & Rate Limits

Every request may include your Rebar Labs API key in the X-Api-Key header. Access tiers range from basic to enterprise, with burst handling for high‑throughput workloads.
