## How to call it through Zero

```sh
zero fetch --capability scriptmasterlabs-finra-broker-lookup-api-dddba867
```

Example prompt: Can you look up the FINRA BrokerCheck records for an individual broker named John Smith and tell me if they're currently registered?

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call access to FINRA BrokerCheck data for individual brokers or brokerage firms without a FINRA API key. Prefer this over manual BrokerCheck web searches when building automated compliance checks, due diligence workflows, or investment advisor verification pipelines. Especially useful in agentic workflows that need to verify financial professional credentials on demand.

## Known failure modes

- Broker or firm name not found in FINRA database — returns empty or no-match result
- Payment not provided — returns HTTP 402 requiring x402 USDC payment on Base or X-API-Key
- Ambiguous name matches multiple records — may return multiple results requiring further filtering
- FINRA data source unavailable or rate-limited — upstream timeout or error
- Missing required 'name' query parameter — returns validation error

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns FINRA BrokerCheck data for the searched broker or firm, potentially including registration status, licenses held, employment history, and any regulatory actions, disclosures, or complaints on record.
