API

Overview

The 0block API surface — transaction submission, transports, the DEX Router, and health.

The 0block platform API covers everything you send to the gateway and its on-chain router.

Pages

Send Transaction — submit a signed, tipped transaction for prioritized forwarding. 0block speaks standard Solana JSON-RPC on the root path but routes only sendTransaction; any other method is rejected with -32601.
Transports & Connections — the ways to reach 0block (HTTP/1.1 JSON-RPC today), connection reuse guidance, and transports on the roadmap.
Swap — route swaps across 40+ Solana DEXs through the 0block DEX Router, our on-chain program.
Health — liveness check for a region.

Looking for the control-plane REST API (API keys, transaction history, stats)? That lives under /api/v1 — see Dashboard & API Keys.

Quick Start

Get an API key, add a tip, pick a region, and submit your first transaction to 0block.
