## How to call it through Zero

Example prompt: Can you pull the FINRA BrokerCheck record for John Smith at Morgan Stanley — I want to know if he has any disclosures on file and see his current registration status and employment history?

## When to prefer this

Use this endpoint when you need to verify the FINRA registration status, disclosure history, or employment background of a US broker or investment advisor. Prefer this over general web searches when you need structured, authoritative FINRA data. Use the CRD parameter for exact lookups when you have the registration number; use free-text query when searching by name and firm. Pair with SEC filings endpoint for comprehensive due diligence.

## Known failure modes

- No results found for query — returns empty results array
- Invalid CRD number format — returns 400 error
- CRD number not found — returns empty results
- Rate limiting or payment failure — returns 402 or 429 error
- Query too vague returns many loosely matched results requiring pagination

## How this service works

FINRA BrokerCheck lookup — every US registered broker / investment advisor (~620k current + former). Search by free-text query (name + firm) or by CRD number for a direct individual record. Each result includes CRD ID, name (with any 'doing business as' aliases), broker-check + IA scope (Active/Inactive), a hasDisclosures flag (yes/no for complaints, settlements, terminations on file), industry-start date, FINRA registration count, and current + previous employments (firm name, branch city/state, registration dates). Public per FINRA's investor-protection BrokerCheck program; pair with /api/finance/sec-filings for cross-reference.

## Output

Returns a list of matching broker/advisor records, each with CRD ID, full name (including DBA aliases), Active/Inactive status for broker and IA scope, a hasDisclosures boolean indicating presence of complaints/settlements/terminations, industry start date, number of FINRA registrations, and arrays of current and previous employment entries (firm name, branch city/state, registration dates).
