## 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 saylor-innovations-perp-funding-rate-lookup-cc192e05
```

Example prompt: What are the current perp funding rates for BTC across OKX, Bitget, Gate.io, Hyperliquid, dYdX, and Deribit — normalized to 8h and annualized — and which way is the market biased?

## When to prefer this

Choose this endpoint when you need a multi-exchange aggregated view of perpetual futures funding rates for a single coin, normalized to a consistent 8h and annualized basis. It is ideal for comparing funding costs across OKX, Bitget, Gate.io, Hyperliquid, dYdX, and Deribit in a single call rather than querying each exchange API individually. Prefer it for funding arbitrage detection, position cost analysis, or market sentiment inference via the long/short bias signal.

## Known failure modes

- Unknown or unsupported coin symbol returns empty venues or error
- Exchange temporarily unavailable reduces venues_responding count
- Rate-limit or payment failure returns 402 or 429
- Stale data if exchanges are slow to respond, reflected in checked_at timestamp
- Some exchanges may not support perpetuals for obscure coins, resulting in partial results

## How this service works

Perp funding rate - current funding for a coin on OKX, Bitget, Gate.io, Hyperliquid, dYdX and Deribit, normalised to 8h and annualized with the long/short bias

## Output

A JSON object containing the queried coin symbol, per-venue data (exchange name, mark price, 8h funding rate %, annualized %, funding interval in hours), aggregate stats (average 8h rate, average annualized rate, funding spread, highest/lowest venues), long/short bias label, number of venues checked and responding, and the UTC timestamp of the check.
