## 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 fold-x402-funding-scan-4bb8662e
```

Example prompt: Scan all 636 perp markets for the most extreme funding rates right now — I only care about markets with at least $500,000 in 24h volume — show me where longs and shorts are most crowded.

## When to prefer this

Use this endpoint when an onchain agent needs real-time funding rate intelligence across a broad set of perpetuals markets, particularly to identify crowded trades or funding arbitrage opportunities. Prefer this over general market data APIs when you specifically need funding rate extremes and position skew signals rather than price or volume data alone.

## Known failure modes

- Payment not provided or invalid x402 payment header — returns 402 Payment Required
- Invalid parameter types (e.g. non-boolean for 'full') — returns 400 Bad Request
- Volume filter too high eliminating all results — returns empty data set
- Service temporarily unavailable — returns 5xx error
- Rate limiting if called too frequently

## How this service works

Machine-readable market intelligence for onchain agents, served over x402.

## Output

A JSON object with status and data fields, where data contains the most extreme funding rate readings across perpetuals markets — highlighting which markets have the most crowded long and short positions at the time of the call.
