## 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 crypto-funding-rate-open-interest-batch-lookup-d42dcaf3 -d '<json body>'
```

Example prompt: Can you pull the current funding rates and open interest for BTC, ETH, SOL, BNB, and AVAX across Binance, Bybit, OKX, and Hyperliquid — I want to see the annualized rates and where the leverage is sitting right now?

## When to prefer this

Use this endpoint when you need to check funding rates and open interest across an entire watchlist in one call rather than querying coin-by-coin. It is ideal for daily market briefs, pre-trade leverage checks, or monitoring multiple positions simultaneously. Prefer the single-coin venue-breakdown endpoint when you need granular per-exchange detail for one asset; use this batch endpoint when breadth across a watchlist matters more than depth on a single coin. The venue-filtering logic makes this more reliable than naive multi-venue averages that overstate funding due to thin books.

## Known failure modes

- Unsupported coin symbols return no data or an error for that coin
- More than 10 coins in a single request may be rejected or truncated
- Venue API outages may result in missing data for specific exchanges
- Coins with no active perp markets on the supported venues return empty results
- Malformed request body causes a 400 error

## How this service works

Perpetual funding rate and open interest for up to 10 coins in a single call, across Binance, Bybit, OKX and Hyperliquid. Answers 'where is the leverage right now?' for a whole watchlist at once. Thin venues are excluded: averaging every venue that publishes a rate overstates BTC funding by ~30x, because a near-empty book printing 9% per 8h counts the same as a deep one. Funding comes per 8h and annualized, so 0.0067% reads as 7.3% a year.

## Output

Returns per-coin funding rate data (8h rate and annualized percentage) and open interest figures, sourced only from liquid venues on Binance, Bybit, OKX, and Hyperliquid. Thin, near-empty books are excluded to avoid distorting aggregates. Results cover up to 10 coins per call, giving a snapshot of where leverage is concentrated across a watchlist.
