/transaction/material/{metadataVersion} REST API Endpoint
Path Parameters
metadataVersion
string
REQUIRED
The version of metadata. The input is expected in a `vX` format, where `X` represents the version number (e.g. `v14`, `v15`). By default, metadata is outputted in 'json' format, unless the `metadata` query parameter is provided, in which case it can be either in 'json' or 'scale' format.
Query Parameters
at
string
Block at which to retrieve the transaction construction material.
metadata
string
Specifies the format of the metadata to be returned. Accepted values are 'json', and 'scale'. 'json' being the decoded metadata, and 'scale' being the SCALE encoded metadata.
