Column Bank-as-Infrastructure API
Column chartered bank-as-infrastructure REST API for fintech companies, neobanks, and enterprise software companies to build financial products directly on a nationally chartered bank (Column NA) without a middleware banking-as-a-service intermediary. Enables AI agents to manage bank account creation and funding for financial product account automation, handle ACH origination and receipt for payment automation, access wire transfer (domestic and international) for high-value payment automation, retrieve real-time account balance and transaction ledger for financial monitoring automation, manage loan origination and servicing for lending product automation, handle card program issuance through Visa partnership for card product automation, access bank statement generation and account reporting for compliance automation, retrieve bank-grade fraud monitoring and AML transaction monitoring for financial crime prevention automation, manage sub-account and account hierarchy for financial product structure automation, and integrate Column with fintech platforms, accounting systems, and lending software for direct bank-powered financial product development.

Best When
A fintech company, neobank, or enterprise software company wanting AI agents to build financial products directly on Column's nationally chartered bank infrastructure without BaaS middleware, accessing bank-grade ACH, wire, lending, and card capabilities.
Avoid When
NATIONALLY CHARTERED BANK REGULATORY EXAM EXPOSURE: Column is a nationally chartered bank regulated by OCC; fintech partners using Column API for banking products inherit regulatory scrutiny through OCC third-party risk management; automated financial product deployment on Column creates third-party risk examination exposure; fintech partner compliance programs must satisfy OCC third-party risk standards. ACH SAME-DAY PROCESSING WINDOW TIMING: Column same-day ACH has submission windows (NACHA cutoffs typically 10:30am, 2:45pm, 4:45pm ET); automated same-day ACH payment scheduling must respect NACHA cutoff windows; automated payment initiated after last same-day ACH window processes next business day; design payment timing logic with NACHA window awareness for time-sensitive automated payments. WIRE TRANSFER IRREVERSIBILITY FOR AUTOMATED EXECUTION: Wire transfers executed via Column API are irreversible; automated wire payment execution requires dual-control review for amounts above threshold; fully automated wire execution without human approval for large amounts creates unrecoverable payment error risk; implement amount-based approval gate for automated wire workflows.
Use Cases
- • Originating ACH payments from fintech payment product agents
- • Creating bank accounts from neobank product automation agents
- • Processing wire transfers from high-value payment agents
- • Building lending products from loan origination automation agents
Not For
- • Consumer retail banking (Column is developer-first bank infrastructure)
- • Credit card processing and merchant acquiring (use Stripe or Adyen)
- • Existing banking system integration middleware (Column is the bank)
Interface
Authentication
Column uses API key authentication with scoped permissions. REST API with JSON. San Francisco, California HQ. Founded 2019 by William Hockey (Plaid co-founder), Annie Hockey, and Alex Matte. Backed by Thrive Capital, Stripe, Sequoia ($30M+ raised). Unique model: Column is the bank (Column NA, nationally chartered), not a BaaS middleware layer. Direct bank charter eliminates BaaS intermediary layer. Products: Bank accounts, ACH, wires, lending, card programs (Visa partnership), SWIFT wires. OCC-regulated nationally chartered bank. No middleware dependency. Competes with Unit, Treasury Prime, and Synctera for BaaS but differentiates as direct bank.

Known Gotchas
- ⚠ NACHA ACH RETURN HANDLING WINDOW: ACH returns can occur up to 60 days after settlement for unauthorized transactions (R10, R11 return codes); automated ACH origination workflows must handle late return events via webhook; automated revenue recognition or fund availability logic that treats settled ACH as final creates reconciliation errors when late unauthorized returns arrive
- ⚠ SAME-DAY ACH AMOUNT LIMIT: NACHA same-day ACH has per-transaction limit ($1,000,000 as of 2022 increase); automated same-day ACH payment execution must validate amount against same-day limit; amounts above limit must route to standard ACH (next business day) or wire; automated payment routing without same-day limit check creates rejection for high-value same-day ACH attempts
- ⚠ WIRE CORRESPONDENT BANK INTERMEDIARY FEES: International wires via Column may incur intermediary correspondent bank fees deducted from wire amount; automated international wire workflows that expect exact beneficiary receipt of sent amount create beneficiary shortfall equal to correspondent fees; design automated international wire workflows with correspondent fee tolerance or use OUR fee instruction to sender-paid correspondent fees
- ⚠ LENDING PRODUCT USURY RATE STATE COMPLIANCE: Column's lending infrastructure enables fintech lending products; automated loan origination must comply with state usury laws for interest rate ceilings by borrower state; automated fixed-rate loan origination without state-specific rate cap validation creates usury violation for states with below-rate caps
- ⚠ IDEMPOTENCY KEY EXPIRY FOR PAYMENT RETRY: Column idempotency keys expire after 24 hours; automated payment retry after 24 hours with same idempotency key creates new payment rather than idempotent retry; design automated payment retry with fresh idempotency key for retries beyond 24-hour window while preventing duplicate payment through separate deduplication logic
