## How to call it through Zero

```sh
zero fetch --capability horizonpulse-perpetual-funding-rates-api-b00ebef7
```

Example prompt: What are the live OKX perpetual funding rates for BTC, ETH, and SOL right now, and is there any crowding signal I should know about?

## When to prefer this

Choose this endpoint when you need real-time perpetual funding rate data specifically for BTC, ETH, and SOL from OKX, especially when you also want a pre-computed crowding signal to assess market positioning without doing your own rate analysis. It complements spot price and technical indicator endpoints on the same platform.

## Known failure modes

- OKX API unavailability causing stale or missing funding rate data
- Rate limiting or payment failure returning 402 or 429 status
- Invalid or missing query parameters returning a 400 error
- Funding rate data delayed during high market volatility periods

## How this service works

Pay-per-call APIs for AI agents via x402 on Base: web fetch, HTTP proxy, page extract, and crypto market data.

## Output

Returns live perpetual funding rates from OKX for BTC, ETH, and SOL, including the raw rate values and optionally a rule-based crowding hint derived from the sign and magnitude of the funding rate (e.g. indicating long or short crowding conditions).
