## 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-hedge-fund-feature-store-institutional-research-exchange-4de2740e
```

Example prompt: Pull the feature store record for MES from the AI Hedge Fund research API — I need to see its coverage and importance metadata.

## When to prefer this

Choose this endpoint when you need structured quantitative feature metadata — specifically coverage and importance signals — for a specific financial instrument ticker, particularly futures contracts. It is read-only and suitable for model enrichment, research screening, and pre-trade analysis pipelines. Prefer it over broker or execution APIs when you only need research-grade feature data, not live prices or order management.

## Known failure modes

- Invalid or unsupported ticker symbol returns empty or null coverage/importance objects
- Missing or malformed 'properties' query parameter may return incomplete records
- Payment failure (non-payment of 0.2 USDC via x402) results in HTTP 402 response blocking data access
- Rate limiting or quota exhaustion returns HTTP 429
- Ticker not in feature store returns empty coverage object with no data

## How this service works

Read-only x402 research APIs. No trading, broker, or execution is exposed.

## Output

Returns a JSON object containing the ticker symbol (e.g. 'MES'), a coverage object describing research coverage dimensions, and an importance object indicating feature importance scores or rankings for that instrument.
