With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability ffiec-bank-institutions-lookup-694b94fb ``` Example prompt: Can you pull up a list of the top 10 active banks in Texas sorted by total assets, including their deposits and net income figures? ## When to prefer this Use this endpoint when you need structured, up-to-date U.S. bank institution data sourced from the FDIC, including filtering by state, name, or certificate number, and sorting by assets, deposits, or other financial metrics. Prefer this over scraping bank websites or general web search when you need machine-readable regulatory and financial data for U.S. federally-supervised banks. Ideal for compliance research, competitive analysis, or verifying a bank's regulatory standing without requiring API keys or signup. ## Known failure modes - Invalid state code returns empty results or error - FDIC certificate not found returns empty bank list - Page number out of range returns empty results - Invalid sort field may return default sort or error - Network/upstream FDIC API unavailability causes failure - Malformed query parameters may result in 400-level errors ## How this service works US FDIC-insured banks (FDIC BankFind call-report data): name, FDIC cert, Fed RSSD ID, location, total assets, deposits and net income (USD), ROA and ROE, report date, charter class, regulator, office counts, holding company, website, established date, active flag and closing date.
