## 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 token-price-momentum-signal-9a955b53
```

Example prompt: Is ETH currently pumping or dumping? Give me the momentum classification and volatility flag from live 24h price data right now.

## When to prefer this

Choose this endpoint when you need a pre-computed, classified momentum signal rather than raw price data — it saves the agent from computing 24h change interpretation logic itself. Prefer it over generic ticker endpoints when the goal is specifically to detect breakouts, crashes, or abnormal price momentum patterns in real time, especially in automated trading or alert workflows.

## Known failure modes

- Unknown or unsupported token symbol returns an error or empty result
- Token has insufficient trading history or volume for meaningful momentum calculation
- OKX data feed temporarily unavailable causing stale or missing data
- Payment not processed correctly resulting in 402 rejection
- Rate limit exceeded if called too frequently

## How this service works

Token price momentum signal from real-time 24h change, classifying pump/dump/rising/falling with volatility flags - a timing signal for trading agents to spot breakouts or crashes, computed from live data LLMs cannot see. token momentum, price momentum, pump detection, dump signal, price breakout, volatility signal

## Output
