Column API
Fully public and documented REST API at docs.column.com (306 public pages, no signup wall). Self-serve signup issues sandbox API keys (test_ prefix) instantly from the dashboard; live keys (live_ prefix) come from the same dashboard once the account is approved for production.
Frequently asked questions
Column scores A on Supergood's API Report Card. Fully public and documented REST API at docs.column.com (306 public pages, no signup wall). Self-serve signup issues sandbox API keys (test_ prefix) instantly from the dashboard; live keys (live_ prefix) come from the same dashboard once the account is approved for production.
Column has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Column (Column N.A.) is a nationally chartered US bank built from the ground up as developer infrastructure. The API is the product: programmable FDIC-insured bank accounts, money movement across every major rail, and lending primitives, all exposed over a public REST API.
Fintech companies building financial products, US and international banks needing correspondent/clearing services, and lenders. The buyer is an engineering team; Column has no meaningful non-API product surface. Fintechs open programmable bank accounts and originate ACH, domestic and international wires, real-time payments, book transfers, and checks via the API.
Core banking infrastructure behind several prominent fintechs (Brex, Mercury, Ramp, Best Egg), but a specialist infrastructure choice rather than a broadly deployed system of record. Most companies touch Column indirectly through products built on it.
Bank accounts and balances, entity KYC/KYB records, full payment and transfer history across all rails (ACH, wire, RTP, book, check), loan records and schedules, statements and documents, webhook event history.
Launched publicly in 2022 on a national bank charter, built API-first from day one.
Common alternatives include Treasury Prime, Unit, Synctera, Cross River Bank, Lead Bank. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of August 2026 there is no official Column MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Column doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
