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 market2000-xyz-portfolio-factors-7a5feac0
```

Example prompt: Break down my portfolio — I'm holding 1000 notional in NVDA and 500 in BTC — into momentum, trend, and beta factors relative to the S&P 500 and BTC using a 90-day lookback window.

## When to prefer this

Use this endpoint when you need a quantitative factor decomposition of a multi-asset portfolio, particularly one mixing equities and crypto. It is purpose-built for momentum, trend, and dual-beta (S&P 500 + BTC) analysis in a single call, making it ideal for agents managing mixed books or performing pre-trade risk checks.

## Known failure modes

- Missing 'holdings' parameter returns an error requiring ticker:weight pairs
- Invalid ticker format or unsupported tickers may return empty or partial results
- Lookback value outside 60–250 range may be rejected or clamped
- Payment failure (x402) if USDC payment is not properly submitted
- Database (clean_prices.db) may lack price history for exotic or newly listed tickers

## How this service works

Portfolio Factors — price-based factor decomposition of a book (clean_prices.db).

HOW TO CALL:
  GET /api/portfolio-factors?holdings=xyz:NVDA:1000,BTC:500

PARAMETERS:
  holdings — TICKER:weight pairs, HL-format tickers (required)
  lookback — estimation window in days, 60–250 (default 120)

RESPONSE: notional-weighted momentum, trend, book beta to S&P 500 and BTC.

PRICING: $0.05 per call.

## Output

Returns notional-weighted factor scores for the submitted portfolio, including momentum, trend, beta to S&P 500, and beta to BTC — giving a quantitative breakdown of the book's systematic risk and style exposures.
