## When to prefer this

Choose this endpoint when you need prediction market probability data specifically contextualized for crypto, altcoin, and memecoin research workflows, and want a cached, low-latency view of Polymarket events without querying Polymarket directly. Particularly useful when already using AltcoinChasersHQ tools for smart-money tracking or wallet forensics and want integrated market sentiment.

## Known failure modes

- Empty events array if no active markets match query or cache is stale
- Stale data if AltcoinChasersHQ cache has not refreshed from Polymarket recently
- Payment failure if USDC balance or x402 payment header is missing or invalid
- Rate limiting or access denial if quota exceeded
- Malformed or missing query parameters returning incomplete results
