Column: a nationally chartered bank API

Column N.A. is a nationally chartered bank built for developers. The docs are the product surface: entities, FDIC-insured bank accounts, ACH, domestic and international wires, realtime payments, checks, loans, and card issuing. Host is https://api.column.com. Dashboard is dashboard.column.com.

There is no Solana surface in the live docs. Adjacent rails stay on their own pieces: UsePaid, Privy fiat.

Auth

HTTP basic auth. API key is the password. Username is blank (the colon before the key is required). HTTPS only. Sandbox keys start with test_. Production keys start with live_. IP allowlists are available if you ask.

curl -u :<YOUR API KEY> https://api.column.com

First objects

An entity is the legal owner. A bank account attaches to that entity. Create account returns default_account_number and routing_number. Extra account numbers are pointers to the same account. They can be added or removed without touching the underlying deposit account.

curl https://api.column.com/entities/person \
  -XPOST -u :<YOUR API KEY> \
  -d first_name=Ada -d last_name=Lovelace

curl https://api.column.com/bank-accounts \
  -XPOST -u :<YOUR API KEY> \
  -d entity_id=<entity_id> \
  -d description="operating account"

The getting-started sandbox walkthrough then simulates an incoming wire, creates a counterparty, and sends an ACH credit. Book transfers move money between your Column accounts instantly.

What the API covers

Opening end-customer accounts is a Program Management Agreement with Column. If you only need a wallet-style FBO, the docs point at Payment Origination instead. KYC/KYB can be yours or Column's. Settlement reports come as CSV, JSON, and Parquet.
