## 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 clonecho-consolidated-prediction-markets-feed-c2250bcd -d '<json body>'
```

Example prompt: Pull up the latest active prediction markets from both Polymarket and Kalshi — I want to see their yes-probabilities, volumes, and close dates all in one list.

## When to prefer this

Use this endpoint when you need a unified snapshot of top active prediction markets across both Polymarket and Kalshi without making separate API calls to each venue. It is cheaper and simpler than integrating each exchange individually, and returns normalized fields so no per-venue parsing is needed.

## Known failure modes

- Upstream Polymarket or Kalshi API unavailable — partial or empty results
- Payment of $0.02 USDC not processed — 402 Payment Required response
- Rate limiting if called too frequently
- Stale data if upstream venues are delayed

## How this service works

Live consolidated prediction-market feed: top active markets across Polymarket AND Kalshi in one call, normalized to {question, yesProb, volume, closeDate}. Cross-venue in a single request — cheaper than querying each. Returns JSON.

## Output

A JSON array of normalized prediction market entries, each containing: the market question, the current yes probability (yesProb), trading volume, and close date — sourced from both Polymarket and Kalshi and normalized to a common schema.
