## 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 api-usenami-io-ee06e5d1
```

Example prompt: Scan all perp tickers across venues and show me any where the funding rate spread between the highest and lowest venue exceeds 20 basis points — I want to see the raw rate difference, not any signal logic.

## When to prefer this

Use this endpoint when you need a quick cross-venue scan to identify which perpetual futures tickers have the largest raw funding rate divergence across all covered venues simultaneously. Prefer this over the per-symbol spread endpoint when you want a market-wide sweep rather than drilling into a single ticker. Note this is a naive filter — it returns raw rate differences with no fee, slippage, or signal logic applied.

## Known failure modes

- Threshold too low returns large noisy result set with many low-signal tickers
- No tickers above threshold returns empty list
- Missing required 'type' or 'method' fields in input object returns 400 validation error
- Stale funding rate data if venue APIs are lagging
- Venue coverage gaps may cause some tickers to appear with fewer data points than expected

## How this service works

Cross-venue funding-rate arbitrage scan over all tracked crypto perpetuals: every ticker whose (max_rate − min_rate) across venues exceeds your threshold. Naive filter, no signal logic — gross spread, before fees, slippage and funding-interval differences.

## Output

A filtered list of perpetual futures tickers where (max_rate - min_rate) exceeds the requested threshold, including per-ticker breakdown of max rate venue, min rate venue, and spread in basis points. No signal logic or edge estimates included — raw rate differences only.
