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 wraith-whale-signals-funding-extremes-12c67208
```

Example prompt: Which perp markets are the most crowded right now and who's paying the funding bill — give me the top ten funding rate extremes with the payer side, rate per interval, and when the next funding hits.

## When to prefer this

Choose this endpoint when you need a quick, pre-ranked snapshot of the most crowded perp funding rate environments across symbols — specifically when you want to know the payer side and timing of the next funding event without having to compute or rank raw funding data yourself. It is ideal for real-time trade entry decisions, risk monitoring, or funding arbitrage scanning where the ten worst-offender markets are sufficient context.

## Known failure modes

- Service unavailable or rate-limited returning a 5xx error if the upstream data feed is down
- Stale data if the underlying exchange feed has not updated recently
- Payment failure or 402 response if the x402 micropayment is not correctly submitted
- Empty or partial result set if fewer than ten symbols have notable funding extremes at query time

## How this service works

Know exactly which market is most crowded and who pays the funding bill — the ten most crowded perp funding rates with payer side, rate per interval, next funding time

## Output

A ranked list of up to ten perpetual futures symbols with the highest (most extreme) funding rates, each entry including: the trading symbol, which side (long or short) is paying the funding, the funding rate per interval, and the timestamp of the next scheduled funding event.
