## 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 ai-momentum-score-trading-data-api-f3ccf5ed -d '<json body>'
```

Example prompt: What's the AI momentum score for ETH right now — I want to know if it has strong bullish momentum before I enter a trade.

## When to prefer this

Use this endpoint when you need a single AI-synthesized momentum signal rather than raw price data, OHLCV, or individual technical indicators. Ideal for trading bots or AI agents that want a pre-computed, high-level conviction score to inform entry/exit decisions without computing their own indicator stack.

## Known failure modes

- Unknown or unsupported ticker symbol returns a 404 or empty result
- Missing required symbol parameter returns a 400 bad request
- Payment not processed (x402 protocol failure) returns 402 Payment Required
- Upstream data unavailable causes 503 or stale score
- Rate limit exceeded returns 429
