## 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 polypulse-polymarket-cross-market-digest-cb5a2209
```

Example prompt: Give me a Polymarket digest showing the top 5 markets per section with at least $10,000 in 24-hour volume — I want to see the biggest movers, markets closing soon, and top by volume all in one shot.

## When to prefer this

Choose this endpoint when you need a broad, multi-section overview of Polymarket activity in a single API call rather than querying individual market endpoints separately. It is ideal for dashboards, daily briefings, or monitoring workflows that need top movers, closing-soon markets, and top-volume markets simultaneously. At $0.02 per call it is the most cost-efficient way to get cross-market Polymarket data versus making three separate endpoint calls at $0.01 each.

## Known failure modes

- Polymarket Gamma API unavailable — returns error or stale data beyond 60-second cache
- min_volume too high — returns empty market lists if no markets meet threshold
- per_section exceeds maximum of 10 — validation error
- Payment not received via x402/USDC — 402 Payment Required response
- Rate limiting or worker timeout on Cloudflare edge

## How this service works

Live Polymarket prediction-market data for AI agents: markets closing soon, biggest movers, top by volume ($0.01 each) and a one-call cross-market digest ($0.02). USDC via x402 on Base.

## Output

A JSON object containing multiple sections (biggest movers, markets closing soon, top by volume) each with up to per_section markets. Each market entry includes the question, yes price, best bid/ask, spread, 24h and 1h price changes, 24h volume in USD, liquidity in USD, outcome probabilities, market end date, and a link to the Polymarket event page. Also includes total count, data source attribution, and a generated_at timestamp.
