How do I get live Polymarket odds and market data without authentication?▼

You can retrieve live Polymarket odds by querying public REST APIs without authentication. This Skill formats current prices, probabilities, and volumes by parsing Gamma fields and mapping clobTokenIds to CLOB endpoints.

What's the best way to track Polymarket price history and recent trades?▼

Tracking Polymarket price history involves querying the Data API endpoints using mapped conditionId values. You can analyze recent trades, open interest, and historical price movements to understand market momentum and activity.

How do I search Polymarket prediction markets by topic or trending volume?▼

Searching Polymarket prediction markets allows discovery by topic, tag, slug, or trending volume. The Skill queries the Gamma API to surface relevant events and markets matching your specified search criteria.

Can I inspect the Polymarket orderbook depth and bid-ask spread programmatically?▼

Inspecting the Polymarket orderbook provides bid-ask spread and depth data via the CLOB API. The Skill formats this orderbook information by mapping clobTokenIds from the initial market metadata response.

Why does parsing Polymarket API data require double-encoded Gamma fields?▼

Parsing Polymarket API data requires handling double-encoded Gamma fields because the Gamma API wraps certain metadata in escaped JSON strings. The Skill automatically decodes these nested structures to extract conditionId and clobTokenIds.
