## 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 algovault-funding-rate-arbitrage-scanner-0b39472c -d '<json body>'
```

Example prompt: Scan all perpetual-futures pairs right now and show me the top 20 cross-venue funding-rate arbitrage opportunities where the funding spread is at least 8 basis points — include the conviction grade and annualized capture for each.

## When to prefer this

Use this endpoint when you need a market-wide sweep of funding-rate arbitrage opportunities across many perpetual-futures pairs simultaneously. Prefer it over `get_trade_signal` when the goal is market-neutral income from funding spreads rather than directional conviction on a single market. It is ideal for agents running periodic opportunity scans or building funding-arb watchlists.

## Known failure modes

- minSpreadBps too high — no opportunities meet threshold, returns empty list
- limit out of range (below 1 or above 200) — returns validation error
- market data feed latency — funding rates may be stale during exchange outages
- payment failure — x402 USDC payment not processed, request rejected
- rate limiting — too many calls in short window returns 429

## How this service works

Ranked cross-venue funding-rate arbitrage scanner: in a single call it scans hundreds of perpetual-futures pairs and surfaces those whose funding spread between venues exceeds a caller-set basis-point threshold. Each opportunity returns the per-venue funding rates, the best long/short venue pair, the spread in bps, the annualized capture, a conviction grade, and the next funding times.

## Output

A ranked list of up to N perpetual-futures funding arbitrage opportunities, each containing: per-venue funding rates, the optimal long venue and short venue, the spread in basis points, the annualized return capture, a conviction grade (e.g. HIGH/MEDIUM/LOW), and the next scheduled funding times for each venue.
