## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability broker-sync-api-prop-firms-list-fdd84f8d -d '<json body>'
```

Example prompt: Show me the full list of prop trading firms that are currently integrated and available through the Broker Sync API, so I know which funded accounts I can connect.

## When to prefer this

Use this endpoint when an agent needs to discover which proprietary trading firms are supported before attempting to connect or sync account data. Ideal as a prerequisite step before fetching positions, balances, or transactions from a prop-firm account. Choose this over the broader brokerage list endpoint when the user is specifically interested in funded/prop trading account providers.

## Known failure modes

- 401/403 if API credentials are missing or invalid
- 402 Payment Required if the x402 micropayment of 0.001 USDC is not included
- 404 if the /v1/prop-firms route is unavailable
- 500 if the upstream SnapTrade service is degraded
- Empty list if no prop firms are currently configured or enabled

## How this service works

Broker Sync API — normalized real positions, balances, and transactions across 30+ brokerages via SnapTrade, plus prop-firm integration status.

## Output

A list of supported prop-firm integrations including firm names, integration status, and metadata about which proprietary trading firms are accessible through the normalized Broker Sync API layer powered by SnapTrade.
