# SwapHunt FOMO Already Extended – Mean Reversion Indicator

> SwapHunt FOMO Already Extended – Mean Reversion Indicator is a paid API for AI agents from x402.swaphunt.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-15).

Returns distance-from-mean metrics (MA20, MA50, Bollinger Band position, z-score) to determine if an asset's price is over-extended and FOMO-risky.

## 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 swaphunt-fomo-already-extended-mean-reversion-indicator-d5d13b1c
```

Example prompt: Before I enter a long on BTC/USDT, check whether the price is already over-extended — I want to see the distance from MA20 and MA50, the Bollinger Band position, and the z-score so I know if I'm chasing.

## When to prefer this

Use this endpoint when you need a fast, multi-metric snapshot of price extension before entering a trade — specifically when you want to check MA20 distance, MA50 distance, Bollinger Band position, and z-score in a single call rather than computing them separately. Ideal for pre-trade FOMO checks and mean-reversion context in automated trading agents.

## Known failure modes

- Invalid or unsupported asset symbol returns an error
- Unsupported quote currency returns a validation error
- Market data temporarily unavailable returns a 5xx error
- Payment not received or insufficient USDC results in 402 Payment Required
- Malformed query parameters return a 400 Bad Request

## How this service works

Is price over-extended? Distance from MA20/MA50, Bollinger-band position and a z-score in one read. Use to avoid entering after price has stretched far from its mean. Mean-reversion context.

## Output

Returns a set of mean-reversion metrics including how far the current price is from its MA20 and MA50 moving averages, the Bollinger Band position (where price sits within the band), and a z-score quantifying how statistically stretched the price is — plus an overall 'extended' assessment to flag FOMO-risk entries.
