## 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 cryptyx-digital-assets-intelligence-api-fc7cf32c
```

Example prompt: Give me a snapshot of BTC, ETH, and SOL from CRYPTYX — I want to see their 1-day returns, 7-day returns, composite rank, and composite score.

## When to prefer this

Choose this endpoint when you need multi-signal composite intelligence scores and rankings for digital assets, not just raw price data. It is ideal for agents comparing crypto assets across many performance dimensions simultaneously, or when composite rank and return metrics across multiple timeframes are needed in a single call.

## Known failure modes

- Invalid or unrecognized asset symbols return empty or partial results
- Missing 'mode' parameter may default to snapshot or return an error
- Payment failure (402) if USDC payment is not successfully processed via x402
- Malformed 'assets' query string (e.g., wrong delimiter) may result in no matching assets
- Rate limiting if excessive calls are made in a short window

## How this service works

Per-asset snapshot or daily series — composite score, rank, recent returns, realised volatility, Sharpe ratios, plus macro regime with confidence. The 200+ asset master ranking feed for portfolio construction and rotation. Coverage: pass any asset in the CRYPTYX 200+ tracked universe (BTC, ETH, SOL, top-cap + long-tail).

## Output

Returns a JSON object with a count of assets and an array of asset objects, each containing the asset symbol, 1-day return, 7-day return, composite rank, and composite score derived from hundreds of signals and metrics.
