The US Bank Directory Lookup API offers quick and efficient access to a comprehensive database of routing numbers for financial institutions across the United States, enabling users to easily retrieve essential banking information.
Each endpoint returns detailed information about US banks, including routing numbers, bank names, cities, states, and transfer types (ACH, Wire, or both). The GET /us-bank-information endpoint provides data for a specific routing number, while the GET /us-bank-information-by-name endpoint returns banks matching a search query.
Key fields include `success` (indicating request status), `routing_number`, `name`, `city`, `state`, `transfer_type`, and `transfer_types` (indicating supported services). The `database_info` field provides context about the data source and coverage.
The response data is structured as a JSON object. It includes a success flag, total records, and an array of bank objects, each containing detailed information. For example, the `banks` array includes routing numbers, names, and locations, making it easy to parse and utilize.
The API provides routing numbers, bank names, locations, and transfer capabilities. The GET /us-bank-information endpoint focuses on specific routing numbers, while the GET /us-bank-information-by-name endpoint allows searching by bank name, returning multiple matches.
Users can customize requests using query parameters such as `transfer_type` (ACH, WIRE, ALL), `limit` (to control the number of results), and `offset` (for pagination). This allows for tailored data retrieval based on specific needs.
The data is sourced from the Federal Reserve's FedACH and Fedwire directories, ensuring high accuracy and reliability. The API provides a `source` field in the response to credit the Federal Reserve as the data publisher.
Typical use cases include verifying bank routing numbers for ACH or wire transfers, integrating banking information into financial applications, and conducting research on US banking institutions. This data is essential for ensuring accurate transactions.
If a routing number is not found, the API returns an HTTP 404 status with `success` set to `false` and `bank` as `null`. For searches with no matches, the `total_matches` field indicates zero results, allowing users to adjust their queries accordingly.
