## 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 market-intelligence-api-price-move-explainer-e80e7739
```

Example prompt: NVDA just moved sharply in the last 15 minutes — can you explain what's driving it, including any on-chain flow, smart money activity, news from the last 48 hours, or SEC filings that might be behind the move?

## When to prefer this

Choose this endpoint when you need a rapid, multi-source attribution of a specific price move for a single ticker — especially when you want on-chain, smart money, news, and regulatory signals all fused into a single ranked response. It is distinct from generic news APIs or order-book feeds because it combines all signal layers into a single weighted explanation per ticker at $0.02 per call.

## Known failure modes

- Unknown or unsupported symbol returns an error or empty driver list
- Stale or missing market data may result in incomplete signal attribution
- Payment failure (x402) blocks the response entirely
- Rate limiting or quota exhaustion returns a 429 error
- Very low-liquidity assets may have sparse or low-confidence signals

## How this service works

Use when a price moves and you need the reason ($0.02): for a crypto, tokenized-stock or US-stock symbol, the move over 15 minutes and its likely drivers from every source (on-chain order flow, unusual activity, smart money, perp crowding, news of 48h, SEC filings, insiders), each with direction and weight, and a one-sentence summary.

## Output

A JSON object containing the 15-minute price move for the requested symbol, a list of likely driver signals (each with type, direction, and weight), and a one-sentence natural-language summary of the move's probable cause. Signal types include on-chain order flow, unusual activity, smart money positioning, perp crowding, 48-hour news, SEC filings, and insider activity.
