Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 asistent-crypto-batch-funding-rate-open-interest-5d78e4b7 -d '<json body>'
```

Example prompt: Pull the current funding rates and open interest for BTC, ETH, SOL, BNB, and DOGE — filter to liquid venues only on Binance, Bybit, and OKX and tell me which ones have elevated funding right now.

## When to prefer this

Choose this endpoint when you need funding rate and open interest for multiple coins simultaneously and want venue-weighted, liquidity-filtered aggregates rather than raw averages that include thin books. It is more efficient and accurate than calling a single-symbol endpoint repeatedly. Prefer this over the single-coin sibling when monitoring a watchlist of 2–10 assets in one shot.

## Known failure modes

- More than 10 symbols requested — endpoint may reject or truncate the list
- Invalid or unrecognized coin symbols return no data for those entries
- Venue API downtime may result in partial data for affected exchange
- Payment failure (insufficient USDC or x402 header missing) returns 402
- Rate or network timeout if upstream exchanges are slow to respond

## 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

A structured response containing, for each requested coin: the funding rate in percent per 8 hours aggregated across liquid venues on Binance, Bybit, and OKX, plus total open interest in USD. Thin or near-empty books are excluded so the aggregate is not skewed by outlier venues. Results cover up to 10 symbols in one response.
