Get an Account by ID

<Callout intent="warning"> The endpoints exposed here are currently in **Beta**! As we continue to build our initial offering, these endpoints may implement breaking changes. Be sure to check back for our change log regularly as a precaution. </Callout> Retrieve one account by its id. The response is identical to that account's entry in `GET /v0/accounts` (a wallet with its per-network `entitlements`, or a bank account with its full `accountNumber` and `beneficiary`), so you never need to reconcile the two shapes. An id belonging to another organization returns `404 account_not_found`, the same as an id that exists nowhere. If your API key can read only one account kind, accounts of the other kind read as `404` too; a key that can read neither gets `403`.
