# Cryptyx Asset Composite Rankings Feed

> Cryptyx Asset Composite Rankings Feed is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns composite scores, ranks, and short-term returns for ~200 digital assets in snapshot or time-series mode for portfolio construction and rotation strategies.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-asset-composite-rankings-feed-ac7e6849
```

Example prompt: Pull the latest composite scores and ranks for all ~200 digital assets in snapshot mode so I can see which cryptos are ranked highest and filter my watchlist.

## When to prefer this

Use this endpoint when you need a broad, ranked view across the full digital asset universe (~200 assets) for portfolio construction, watchlist filtering, or rotation signal generation. Prefer this over single-asset endpoints when you need a comparative ranking across many assets simultaneously. Use snapshot mode for current state and series mode for backtesting or trend analysis.

## Known failure modes

- Invalid mode value returns an error — must be 'snapshot' or 'series'
- Unrecognized asset symbols in the assets query param may be silently ignored or return empty entries
- Payment not included or insufficient USDC (x402) results in 402 Payment Required
- Rate limiting may apply if called too frequently
- Network timeout if the full ~200-asset universe is requested in series mode

## How this service works

CRYPTYX | institutional-grade crypto intelligence: 150+ signals, 440+ metrics, 200+ assets. | Bare JSON array of per-asset rows from api.asset_universe_timeseries_v1 (analytics.v_composite_ux + TR_RET + VOL_RV). Snapshot mode returns latest canonical day cross-section; series mode returns last N days (default 30, max 365). Filter by assets= and/or universes= CSV. Each snapshot row: asof_day, asset, universe_tag, comp_score, comp_rank_eq, comp_rank_pct, price_anchor, ret_1d/7d/30d, vol_rv_7d/30d, sharpe_7d/30d, plus macro `regime` (expansion/consolidation/deleveraging) + `regime_confidence`. ~200-asset master ranking feed for portfolio construction and rotation, with regime gating in the same call.

## Output

A JSON array of up to ~200 digital assets each with their composite score, composite rank, 1-day return, 7-day return, factor breadth, and conviction count — returned either as a current snapshot or as a time series depending on the mode parameter.
