## 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 hostdefi-prediction-markets-feed-bc1990c2
```

Example prompt: Pull the top 50 active prediction markets right now — I want to see the yes/no prices, 24-hour volume, and settlement dates for each one.

## When to prefer this

Use this endpoint when you need a live, paginated feed of prediction markets with yes/no prices and volume data, especially when integrating with a Polymarket-sourced dataset. Prefer it over direct Polymarket API calls when operating within an x402 micropayment-enabled agent workflow, or when you need a unified DeFi-native data source that co-locates with swap and bridging capabilities on the same host.

## Known failure modes

- Invalid 'limit' parameter (outside 1–500 range) may return a validation error
- Network or RPC node downtime may result in failed requests or empty responses
- Payment not attached or insufficient USDC (0.005 required per call) returns a 402 Payment Required
- Upstream Polymarket data unavailability may cause stale or empty market lists

## How this service works

HostDeFi is a Solana DEX with a free token safety scanner. Best-route swaps through Jupiter, EVM trading across 7 chains, native bridging, and live token risk grades. No KYC, 1% flat fee.

## Output
