Fetch Markets Paginated

Fetch markets with cursor-based pagination backed by a stable in-memory snapshot. On the first call (or when no cursor is supplied), fetches all markets once and caches them. Subsequent calls with a cursor returned from a previous call slice directly from the cached snapshot — no additional API calls are made. The snapshot is invalidated after snapshotTTL ms (configured via ExchangeOptions in the constructor). A request using a cursor from an expired snapshot throws 'Cursor has expired'.

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.
