## 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 quotient-prediction-market-trade-signals-feed-2f59b561
```

Example prompt: Pull Quotient's latest prediction market trade signals — show me the YES-side ones with high conviction and at least $500 in capacity available on Polymarket or Kalshi.

## When to prefer this

Use this endpoint when you need a full list of all currently published Quotient trade signals across prediction market venues — ideal for scanning the entire signal book, building dashboards, or filtering by side, conviction, and capacity. Prefer the single-best-signal endpoint if you only need the top idea right now, or the market-search endpoint if you want to find markets by theme rather than by signal status.

## Known failure modes

- No signals available if Quotient has no current active research for requested filters
- Empty result set when filtering by side/conviction/capacity returns no matches
- Payment failure if x402 USDC payment of $0.006667 is not processed correctly
- Service unavailability due to Render.com cold starts causing slow initial response
- Stale signals if market conditions have changed since signal publication

## How this service works

Use this to scan Quotient's published prediction-market signals on Polymarket International, Polymarket US, Kalshi, and Limitless: side, entry YES price, latest Q probability and thesis, conviction, the forecast_status gauge with its standing adverse move, upside to Q, and capacity — one signal per market. A signal is active or retired; a missing live quote drops a row from the feed, and a caution/warning forecast_status marks an adverse move; the row remains listed.

## Output

A list of trade signals, each containing the market identifier, recommended side (YES/NO), suggested entry odds, conviction tier, spread versus venue price, convergence upside in cents, available capacity in USD, signal status, and timestamp — ordered newest first.
