post https://{server_url}/{api_key}/v1/tables//item
Get a table item at a specific ledger version from the table identified by {table_handle}
in the path and the "key" (TableItemRequest) provided in the request body.
This is a POST endpoint because the "key" for requesting a specific
table item (TableItemRequest) could be quite complex, as each of its
fields could themselves be composed of other structs. This makes it
impractical to express using query params, meaning GET isn't an option.
The Aptos nodes prune account state history, via a configurable time window.
If the requested ledger version has been pruned, the server responds with a 410.
