## 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 aisa-mpp-data-apis-polymarket-simplified-markets-b072f906
```

Example prompt: Pull me the current list of active Polymarket prediction markets with their token prices and reward rates — start from the beginning with no cursor.

## When to prefer this

Choose this endpoint when you need a lightweight, summarized view of Polymarket CLOB markets including token prices and reward rates, without requiring full order book depth. Prefer it over full market endpoints when you want a quick scan of market states, winner flags, or reward structures across many markets.

## Known failure modes

- Invalid next_cursor value returns empty or error response
- No markets returned if all are archived or the cursor is exhausted
- Rate limit or payment failure if USDC balance is insufficient for the $0.012 per-call fee
- Stale data if Polymarket upstream is delayed
- Empty data array when no markets match current state

Also includes total count, limit, and next_cursor for pagination.
