## 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-perpetuals-support-resistance-levels-dcddc6d9
```

Example prompt: What are the nearest support and resistance levels and the range top and bottom for BTC perps right now?

## When to prefer this

Use this endpoint when an onchain or AI agent needs machine-readable technical price levels (support, resistance, range top/bottom) for crypto perpetual markets, especially when paying per-call via x402 micropayments. Prefer this over general-purpose price feeds when you need structured market structure intelligence rather than raw price ticks.

## Known failure modes

- Missing or invalid symbol returns an error (e.g. unknown ticker)
- Payment not provided or insufficient USDC balance causes 402 Payment Required response
- Network or upstream data unavailability may result in 5xx errors
- Symbol for a non-supported perp market returns empty or error data

## How this service works

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

## Output

A JSON object with a 'status' field (e.g. 'success') and a 'data' object containing the nearest support level, resistance level, range top, and range bottom for the requested perpetuals symbol — structured for direct consumption by onchain agents.
