## 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 robinhood-chain-funding-rate-scanner-9e0d43cb -d '<json body>'
```

Example prompt: Show me the top 20 perpetuals with the most extreme funding rates right now across Hyperliquid, Binance, and Bybit so I can spot funding arbitrage opportunities.

## When to prefer this

Use this endpoint when you need a real-time cross-exchange funding rate scan in a single pay-per-call request with no API key setup. Prefer over manually querying individual exchange APIs when you need aggregated, ranked funding data across Hyperliquid, Lighter, Binance, and Bybit simultaneously for arbitrage or directional sentiment analysis.

## Known failure modes

- Upstream exchange API unavailable — partial or empty results returned
- limit parameter exceeds 50 — capped or error returned
- Payment not settled — 402 response requiring stablecoin payment
- Stale data if exchange feeds are delayed

## How this service works

Cross-venue funding scan for every tokenized-stock perp: each ticker's funding across Lighter/Hyperliquid/Binance/Bybit, ranked by the most extreme rate, with mark price and a crowded-long/short squeeze bias. Send { limit? }. Spot the most squeezed tokenized-stock perps in one call.

## Output

A ranked list of perpetual markets with current funding rates, exchange source, asset/pair, and funding spread data — up to the specified limit (default 15, max 50). Useful for identifying funding arbitrage between venues or spotting markets with extreme sentiment-driven funding.
