API Documentation

There are a few ways to access the Cronos POS Chain

  1. Tendermint RPC

  • Raw but most-completed data

  • Hosted documentation (use the latest master only): https://docs.tendermint.com/master/rpc/

  • Swagger file: https://github.com/tendermint/tendermint/blob/v0.34.3/rpc/openapi/openapi.yaml

  1. gRPC Based

  • Processed chain information. Old state may be pruned from time-to-time. To avoid state pruning, update pruning = "nothing" in ~/.chain-maind/config/app.toml

  • There are two query methods based on gRPC:

    1. gRPC Server

    2. gRPC Proxy RESTful Server

      • Swagger UI

      • Swagger file

API Clients and libraries

  • TypeScript library

  • Python library

  • Rust library (note that it is not feature complete)

  • @cosmjs/stargate

Indexing

  • chain-indexing (indexing on-chain data)

Node Monitoring (Prometheus)

The Ansible playbook for deploying Prometheus and some rules we are using are under chain-integration/monitoring.
