## How to call it through Zero

Example prompt: Pull the latest Polymarket CLOB implied probabilities and 24-hour smart-money volume movers for crypto markets — I want to see the bid-ask spreads and which events are seeing the biggest moves.

## When to prefer this

Choose this endpoint when you need real-time, sanitized Polymarket prediction market data — specifically implied probabilities, bid-ask spreads, and smart-money volume signals — across crypto, macro, or geopolitics categories, without having to query and clean Polymarket's raw CLOB API yourself. Prefer it over direct Polymarket API calls when you need a curated, ready-to-use signal feed for agents.

## Known failure modes

- Invalid or missing category field may return default (crypto) or an error
- Polymarket CLOB data unavailable or delayed due to upstream outage
- Payment failure (x402) if USDC balance is insufficient
- Malformed request body returns schema validation error
- Category outside supported enum values may return empty results
