How this service works
FDIC-insured bank institutions in one US state from the FDIC BankFind API: name, certificate number, address, ZIP, charter class and whether the bank is active. Institution data only; no financial statements.
Output
A JSON object containing the queried US state, total number of institutions found, the FDIC source URL, a timestamp, and an array of institution objects each with ZIP code, FDIC certificate number, institution name, active status, street address, latitude, longitude, state name, insured date, and charter class.
Example use cases
Regional bank coverage research
“List up to 30 FDIC-insured banks in Texas — I want their names, addresses, and whether they're still active.”
Compliance due diligence by state
“Can you find me FDIC-registered banking institutions in New York? I need the charter class and insured date for each one.”
Bank geolocation mapping
“Get me the FDIC bank institutions in Florida with their latitude and longitude so I can plot them on a map — give me 50 results.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/fdic-bank?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official FDIC-sourced data on insured banking institutions filtered by US state, including location coordinates, charter class, and insurance history. Prefer this over generic bank directories when regulatory accuracy and FDIC certification status are required, or when you need geospatial bank data for a specific state. It is pay-per-call with no API key required, making it ideal for on-demand agent workflows.
Side effects
- Missing required 'state' parameter returns an error
- State name not matching FDIC format (e.g. 'CA' instead of 'California') may return empty results or error
- Limit outside 1–50 range may be rejected or clamped
- Network or upstream FDIC API unavailability causes call failure (no charge on failure)
- Non-US states or territories may return zero results
