## 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 solenrich-perps-market-trend-87cb03ae -d '<json body>'
```

Example prompt: Are perp markets currently growing, stressed, or rebalancing? Pull the 30-day trend deltas for mark price, open interest, long/short skew, utilization, and borrow APR across venues and give me the directional signals in JSON format.

## When to prefer this

Use this endpoint when building regime-detection strategies or bots that need to adapt behavior based on whether perp markets are expanding, stressed, or rebalancing — specifically when you need multi-metric directional signals (OI, skew, utilization, borrow APR) across Solana-based perp venues over configurable lookback windows rather than raw spot or funding data alone.

## Known failure modes

- Invalid lookback value returns validation error
- Invalid format enum returns validation error
- Upstream on-chain data unavailable causes partial or empty response
- Rate limiting or payment failure (x402) blocks the call
- Stale data if on-chain indexer lags behind real-time

## How this service works

Per-symbol deltas for mark price, total OI, long/short skew, utilization, and borrow APR over 7/14/30 days. Direction indicators per metric and per market. Overall direction excludes mark price (price moves are not health signals). Required for regime-detection strategies and any bot that adjusts behavior based on whether markets are growing, stressed, or rebalancing. Mirror of token-trend for perps.

## Output

A structured JSON (or LLM-friendly text) payload containing per-symbol deltas for mark price, total open interest, long/short skew, utilization, and borrow APR over the selected lookback window; plus directional indicators (up/down/flat) per metric per market; and an overall market direction signal (excluding price) indicating whether markets are growing, stressed, or rebalancing.
