Key naming follows the-odds-api conventions, so integrations migrating to a compatible API keep their market vocabulary. The prop keyspace is huge and sport-specific - discovering what exists per sport programmatically beats hardcoding.
The live catalog at /v1/meta/markets enumerates every active key - ParlayAPI serves 4,000+ distinct prop market keys in a typical 24 hours across its sports. Requests filter by key, and every outcome in a response states its key, point value, and price.
