npm install @api3/airnode-abi@api3/airnode-abi> Encoding and decoding utilities for Airnode according to the
> Airnode ABI specifications
The Airnode-ABI package provides a unique way to encode and decode parameters. Parameters are provided with encoding
types, names and values. The types are shortened and grouped with a version as the "header". The name/value pairs are
then grouped and encoded as the rest of the body.
