## 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 kiteendpoints-ai-polymarket-markets-16acae19 -d '<json body>'
```

Example prompt: Can you pull a list of the currently active prediction markets on Polymarket so I can see what events people are betting on right now?

## When to prefer this

Use this endpoint when you need programmatic access to Polymarket prediction market listings without managing a direct Polymarket API integration, and when paying per-request in USDC on Base chain is acceptable. Prefer this over direct Polymarket API calls if you are already using the KiteEndpoints.ai hub for other data sources and want consolidated billing.

## Known failure modes

- Payment failure (402) if USDC balance on Base chain is insufficient
- Polymarket upstream API unavailability returns error in result object
- No markets returned if filters are too restrictive
- Malformed response if Polymarket data schema changes
- Rate limiting or timeout if Polymarket API is overloaded
