Public endpoints

Public endpoints are rate limited but can be used for basic CLI usage, node syncing or testing environments. Request an API key for enhanced access limits, we offer free trial periods of 14 days and cheap shared access plans from $50 a month.

REST/LCD

REST endpoint for querying blockchain data through the REST framework. Often available for Cosmos chains but also the main framework for Aleo as an example.

rest.lavenderfive.com:443/tac

RPC

Remote Procedure Call endpoint for the consensus client of a blockchain. This is not an EVM endpoint (we call this json RPC) but the main framework for blockchain frameworks like Cosmos, Aptos, Sui and Near.

rpc.lavenderfive.com:443/tac

gRPC

High-performance RPC endpoint for blockchain communication using the Google gRPC framework. This is often standard gRPC and not the "WEB" framework which is sometimes also accesible.

tac.lavenderfive.com:443

WebSocket

WebSocket endpoint for real-time blockchain updates of the consensus client. This is not the EVM websocket integration, we name and expose that separately. WS is commonly available for Cosmos and Move networks that also expose a REST endpoint.
