# getHistoricalAccountInfo

## getHistoricalAccountInfo — Historical account lookup at a chosen position

> Returns the state of \`pubkey\` at a chosen historical position.\

> \*\*Parameters\*\*\
> \
> 0\. \`pubkey\` (required) — base58 account pubkey.\
> 1\. \`config\` (required) — positioning + encoding options. One of \`slot\` (end-of-slot, optionally with \`writeVersion\` for inside-a-slot) or \`anchor\` must be set.<br>
