Uniblock JSON-RPC API
The Uniblock JSON-RPC API provides a single endpoint for standard JSON-RPC calls across hundreds of blockchain networks. Rather than managing individual node provider connections for each chain, developers can send JSON-RPC requests through Uniblock which automatically selects the best upstream node provider. This supports standard Ethereum and EVM-compatible JSON-RPC methods, as well as Solana and other chain-specific RPC interfaces, with built-in failover and automatic retries.
Uniblock JSON-RPC API is one of 7 APIs that Uniblock publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
Tagged areas include Blockchain, EVM, JSON-RPC, Nodes, and Web3. The published artifact set on APIs.io includes API documentation and an OpenAPI specification.
This API exposes 1 operation across 1 path, and defines 4 schemas. It is described by OpenAPI 3.1.0, at version 1.0.
Requests are made against a single base URL, https://api.uniblock.dev/direct/v1.
