## 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 greeneris-derivatives-funding-arbitrage-scanner-fb57298c
```

Example prompt: Scan BTC, ETH, SOL, XRP, and DOGE for funding rate arbitrage opportunities across derivatives venues and show me the biggest spreads in annualized percentage terms.

## When to prefer this

Use this endpoint when you need a cross-venue funding rate arbitrage scan for major crypto assets in a single call, returning structured long/short venue pairs with spread APR and open interest. Prefer this over manually querying individual exchange APIs when you want a ready-to-act arbitrage signal without building your own venue aggregation logic.

## Known failure modes

- HTTP 402 if payment not provided — endpoint returns machine-readable USDC quote for x402 payment
- Invalid or unsupported symbol in the comma-separated list returns an error or is silently skipped
- Requesting more than 12 symbols at once may result in a validation error
- No opportunities found if funding rates are converged across venues — empty opportunities array returned
- Network timeouts if upstream venue APIs are slow or unavailable

## How this service works

Cross-venue funding-rate arbitrage screener for crypto perpetuals: for each symbol, identifies the venue to SHORT (highest annualized funding) and the venue to LONG (lowest), with the gross APR spread and per-leg open interest in USD, ranked by spread. Query: ?symbols=BTC,ETH,... (max 12, sensible default list). JSON, ~30s cache. Excludes fees/slippage; informational only.

## Output

Returns a list of arbitrage opportunities with the best long and short venue for each symbol, the funding APR on each leg, open interest in USD, and the gross spread APR (difference between the two legs), plus a list of all symbols scanned.
