Bank Lookup

Overview

A bank lookup API for KYB, payments and vendor onboarding. One registry joins the FDIC BankFind data (all ~28,000 bank charters, active, merged, failed and closed) with NCUA credit union filings, then attaches the routing numbers and SWIFT codes we hold for each active institution. Every match carries its status and status date, the establishment date, headquarters address and coordinates, website, regulator, FDIC certificate or NCUA charter and RSSD id. Look up a routing number and routingCheck tells you whether it still belongs to an active institution. Look up an IBAN or a SWIFT code outside the US and you get the bank from our SWIFT directory. Paid plans add the successor for merged charters, failure details for failed banks, the LEI, quarterly total assets, deposits, net income and credit union membership, plus branches=true for the branch list.

Formula

One function covers the whole catalog: the first argument names the source, the next are its inputs, and the field after them says which single value lands in the cell. Formulas covers the grammar that applies to all of them.

=VERVE("banklookup", "count")

=VERVE.CALL("banklookup", "count")

Inputs

Required inputs are positional, in the order below, followed by the field. Everything else is passed as a "name", value pair after that — the same shape as SUMIFS. Premium inputs are accepted on every plan but only take effect on plans that include them.

Passing an option

=VERVE("banklookup", "count", "name", "Wells Fargo")

=VERVE.CALL("banklookup", "count", "name", "Wells Fargo")

What lands in your sheet

The field — the argument after the inputs — is what makes the formula resolve to one cell. Its value is a dot-path from the table below, so swapping it is how you pull a different value — one formula per column.

Seeing everything at once

Leave the field out and the formula returns the whole response instead: two columns, field name on the left and value on the right, spilling from the cell you typed in.

=VERVE("banklookup")

=VERVE.CALL("banklookup")

Response fields

Paths are relative to data. Each one is exactly what the field argument accepts, so swapping it is how you pull a different value into a cell. On a plan without a Premium field the cell reads #PREMIUM(field) rather than a value, so a locked field never looks like a real answer.

When a cell doesn't fill

A failed lookup returns readable text starting with #ERR rather than a spreadsheet error, because Excel cannot show a custom message on a real error — you would get a bare #VALUE! with no reason. The trade-off is that IFERROR() will not catch it; test with LEFT(cell, 4) = "#ERR" instead. Error handling covers the rest.

Before the formula works

The add-in reads the API key you saved once in the side panel — the key never goes in the formula, so a shared sheet does not leak it and a collaborator without access simply sees the last calculated values.

1. Install the add-in for Google Sheets or Excel.
2. Open the side panel and sign in, or paste a key from your dashboard.
3. Type the formula above into any cell.

Use cases

KYB and Vendor Onboarding

Confirm that the bank a business names is a real, insured institution that is still operating, and record its FDIC certificate or NCUA charter with the file.

Payment Instruction Checks

Before paying a new routing number, check that it belongs to an active institution and that its owner matches the bank named on the invoice.

Bank Merger Tracking

Map an old bank name on a cheque or statement to the institution that absorbed it, with the date of the merger.

Market Research

Rank banks and credit unions in a state by assets and branch count from quarterly regulatory filings.

Other ways to use Bank Lookup

Set up Bank Lookup on VerveSheets, or reach the same source a different way. Your VerveSheets account and credits work on all of them — one key, one balance.
