This endpoint should only be used when querying a node for a block does not return all transactions contained within it. All transactions returned by this endpoint must be appended to any transactions returned by the /block method by consumers of this data. Fetching a transaction by hash is considered an Explorer Method (which is classified under the Future Work section). This method can be used to let consumers to paginate results when the  block trasactions count is too big to be returned in a single BlockResponse. Calling this endpoint requires reference to a BlockIdentifier because transaction parsing can change depending on which block contains the transaction. For example, in Bitcoin it is necessary to know which block contains a transaction to determine the destination of fee payments. Without specifying a block identifier, the node would have to infer which block to use (which could change during a re-org). Implementations that require fetching previous transactions to populate the response (ex: Previous UTXOs in Bitcoin) may find it useful to run a cache within the Rosetta server in the /data directory (on a path that does not conflict with the node).",

If live data is required for construction, it MUST be fetched in the call to `/construction/metadata`. The caller can provide a max fee they are willing to pay for a transaction. This is an array in the case fees must be paid in multiple currencies. The caller can also provide a suggested fee multiplier to indicate that the suggested fee should be scaled. This may be used to set higher fees for urgent transactions or to pay lower fees when there is less urgency. It is assumed that providing a very low multiplier (like 0.0001) will never lead to a transaction being created with a fee less than the minimum network fee (if applicable). In the case that the caller provides both a max fee and a suggested fee multiplier, the max fee will set an upper bound on the suggested fee (regardless of the multiplier provided).",
