Paginated catalog of verified cross-venue matched markets
Returns embedding-verified cross-venue market matches (verified matches only), joined against market metadata for display (title, ticker, images, expiry, status). min_similarity is clamped server-side to never go below a minimum threshold regardless of what the caller passes. Pairs are dropped if either correlation side has expired, if either side references a provider that is unknown or not currently indexing-enabled, or if either side’s resolved market status is settled/closed/resolved; a side with no metadata available (unmirrored rather than de-indexed) is kept with null display fields. has_more reflects whether the underlying page (before the live-status post-filter) was full, so it is not a strict function of the returned count/pairs length. total is only computed (filters applied before the live-status post-filter) when include_total=true. This is treated as a primary, non-additive endpoint: any backend failure returns 503 rather than a degraded/empty result.

}Query Parameters
Maximum number of pairs to return.
1 <= x <= 1000Legacy pagination offset. Do not combine with cursor.
x >= 0Opaque keyset cursor. Send an empty value on the first page, then pass each response next_cursor. Cursor mode orders by immutable canonical pair identity so catalogue mutations cannot shift page boundaries, and binds every page to one full-set fingerprint.
16384Filter to pairs where either side belongs to this provider. Must resolve to a known provider name (case-insensitive) or the request fails with 400.
Minimum embedding similarity score. Always clamped up server-side to a minimum threshold even if a lower value is supplied.
0 <= x <= 1Sort column. Must be "similarity" or "updated_at"; any other value fails with 400.
similarity, updated_at When true, runs an additional COUNT query and includes the total matching-pair count in the response.
Response
A page of verified cross-venue matched market pairs.

Number of pairs on this page after live-status post-filtering (may be less than limit).

Whether the underlying page (before live-status post-filtering) was full — not a strict function of count.
Opaque cursor for the next keyset page. Present when cursor mode is requested.
Full-set fingerprint shared by every page in one cursor walk.
Only present when include_total=true. Total matching-pair count under the pre-live-filter query filters.
