## 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 signalpulse-polymarket-fx-equity-binary-scan-57f8f871
```

Example prompt: Scan all Polymarket Up/Down binary markets across FX pairs and equities — including SPY — and show me the single best mispriced market right now based on fair value vs the live order book, plus the full breakdown of every market you checked.

## When to prefer this

Choose this endpoint when you need a quantitative, model-driven edge check on Polymarket Up/Down binary markets specifically for FX or equity assets, grounded in realized volatility, options skew, and technicals — not just raw market prices. Prefer it over generic Polymarket data feeds when you need the fair-value-vs-CLOB comparison with a fill-depth check in a single call. Use the ?class= filter when you only care about one asset class to reduce noise.

## Known failure modes

- Polymarket CLOB unavailable or stale — scan may return degraded or no signal
- No divergences detected above threshold — returns empty best signal with full scan still populated
- Invalid ?class= parameter value returns 400 error
- Rate limiting or payment failure (x402) returns 402 Payment Required
- Realized volatility data unavailable for one or more assets — those markets excluded from scan

## How this service works

Polymarket daily Up/Down binary scan across 11 FX pairs and 18 equities (incl SPY): each market is priced to a fair probability band from realized volatility, FX options skew, and technicals, then compared against the live CLOB book. Returns the single best interval-disjoint divergence with a depth-gated fill check, plus the full transparency scan of every market checked. Optional ?class=fx|equity narrows the universe.

## Output

Returns the single best interval-disjoint divergence opportunity (the market, fair probability band, live CLOB price, divergence magnitude, and a depth-gated fill check confirming liquidity) plus a full transparency scan listing every one of the 29 markets evaluated with their fair value ranges and current market prices.
