# getAccountDiff
## getAccountDiff — Two-point diff for one account
> Two-point diff for a single account. Each side accepts the same positioning modes as \`getAccountInfo\` — end-of-slot via \`slotA\`/\`slotB\`, or per-transaction via \`anchorA\`/\`anchorB\`. Fields are suffixed \`A\`/\`B\` so both sides coexist in one config object.\
> \
> \*\*Parameters\*\*\
> \
> 0\. \`pubkey\` (required) — base58.\
> 1\. \`config\` (required) — see fields below.
