## How to call it through Zero

Example prompt: Can you look up Wells Fargo Bank by name in the FDIC database and tell me its insurance status, charter class, total assets, and how many offices it has?

## When to prefer this

Use this endpoint when you need authoritative FDIC regulatory data about a US bank — insurance status, charter class, asset/deposit totals, or branch count — either by exact certificate number for a precise lookup or by institution name for a search. Prefer over general web search when you need structured, machine-readable bank metadata for compliance checks, due diligence, or financial enrichment workflows.

## Known failure modes

- Certificate number not found — returns empty results or 404
- Name search returns zero matches if spelling is too different from registered name
- Ambiguous name matches many institutions — returns up to limit without a definitive single result
- Invalid cert parameter type (non-numeric) — validation error
- limit parameter out of range (>20 or <1) — may return error or be clamped
- FDIC data source temporarily unavailable — upstream timeout or 503

## How this service works

Look up an FDIC-insured US bank by certificate number or name: insurance status, charter class, location, offices, assets and deposits.

## Output

Returns FDIC bank record(s) including institution name, certificate number, insurance status, charter class, headquarters location, number of branch offices, total assets, and total deposits. Name searches return up to the requested limit (default 5, max 20) of matching institutions.
