Parameters

Name	In	Type	Description
markets	query	string	Comma-separated market slugs (1-10). Mutually exclusive with market_keys; legacy default venue is polymarket.
market_keys	query	string	Preferred comma-separated globally unique marketKey values (1-10). Mutually exclusive with markets.
venue	query	"polymarket" \| "polymarket_us" \| "kalshi" \| "limitless"	Optional prediction-market venue filter. Omit it on catalog/feed routes to include every covered venue. On legacy slug or condition-ID lookups, omission retains the Polymarket namespace; prefer marketKey for collision-safe cross-venue lookup.

types	query	string	Comma-separated subset of: article, x_post. Default: both.

One request may be in flight at a time, and request starts must be at least one second apart. A rejected 429 is not billed. See rate limits.
