Maximum number of rows to return in one page (at most 100). A larger value, or a non-positive one, is rejected with 400 invalid_query -- so a short page means the result set is exhausted, not that the server quietly capped you (#9916). Omitted, the server applies 50.

Number of rows to skip before the page begins. Correct only in combination with the page size the response actually returned -- prefer cursor for anything beyond the first few pages, since a row inserted mid-scan shifts every later offset.

Opaque pagination token: pass back the next_cursor from the previous response verbatim. Its contents are not stable and must not be parsed or constructed. Stable across inserts, unlike a row offset.

Inclusive first observed_at bound, as epoch MILLISECONDS -- not a block height (use block_start/block_end for that). Omit for an unbounded end. Must not be later than the range's upper bound.

Inclusive last observed_at bound, as epoch MILLISECONDS -- not a block height (use block_start/block_end for that). Omit for an unbounded end. Must not be earlier than the range's lower bound.

Inclusive first block height of the range to read. Omit for an unbounded end. Must not be later than the range's upper bound.

Inclusive last block height of the range to read. Omit for an unbounded end. Must not be earlier than the range's lower bound.

Inclusive lower bound: only rows at or above this value are returned.

Inclusive lower bound: only rows at or above this value are returned.

Response format override. Use csv to download the route rows as text/csv; json keeps the default response envelope.
