## 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-perpetual-funding-rate-signal-511f823a -d '<json body>'
```

Example prompt: What are the current funding rates and annualized carry for BTC, ETH, SOL, and the other top crypto perpetuals right now — and which one has the strongest directional bias?

## When to prefer this

Use this endpoint when you need a pre-processed, ranked funding-rate signal across 8 major crypto perpetuals rather than raw tick data from an exchange. Ideal for carry trade screening, directional bias monitoring, or when you want annualized carry already computed and ranked — not when you need full order book data, historical rates, or coins outside the supported 8.

## Known failure modes

- Upstream exchange API outage may return stale or missing data for one or more coins
- Network timeout if the pricing data feed is momentarily unavailable
- JSON payload may be empty or partial if fewer than 8 coins have fresh data

## How this service works

Live crypto perpetual funding-rate signal for 8 top coins (BTC, ETH, SOL, XRP, DOGE, BNB, ADA, AVAX): 8h funding rate, annualized carry %, directional bias, and spot — ranked by carry magnitude. A derived signal, not raw prices. Returns JSON.

## Output

A JSON array of up to 8 coins (BTC, ETH, SOL, XRP, DOGE, BNB, ADA, AVAX), each with their current 8-hour funding rate, annualized carry percentage, directional bias (long/short pressure indicator), and spot price, ranked from highest to lowest carry magnitude.
