Fetch Events

Fetch events with optional keyword search. Events group related markets together (e.g., “Who will be Fed Chair?” contains multiple candidate markets).

Faster with an API key — With a PMXT API key this endpoint is served from an indexed catalog (~10 ms) instead of proxying to the venue (~500 ms). No code changes required — same request, same response, just faster. Learn more.
