API Docs

Libre Public API servers are provided by validators and apps.

• Anyone can run an API node for Libre or Become a Validator

• A full list of public APIs are available for Mainnet or Testnet.

Please note that regardless of what the swagger docs below say there is a general rule we recommend for using /v1/ and /v2/ paths:

/v1 use POST

/v2 use GET

There is a helpful doc outlining API Methods here - (built by validator Cryptobloks)
