market, and optionally by one exact venue-native instrument; omit instrument for the whole chain.

Query parameters
Access and behavior
With no bounds, the API queries the latest hour anonymously. Explicit bounds inside the rolling last hour are also public; older history requires a Polaris API key.start and end are inclusive collector timestamps in Unix milliseconds. With only start, the query runs through now; with only end, it covers the preceding hour, clamped to the anonymous cutoff. Anonymous reads are capped at 1 GiB per request and two concurrent queries per API replica. Rows that age out of the public hour are skipped during anonymous pagination.
Response
items[] fields
Decimal prices, sizes, implied volatilities, and Greeks remain strings to preserve their normalized representation. Null means that observation did not provide a value. See option ticker event fields for the SDK envelope.
Pagination
Passnext_cursor as cursor with the same filters. Stop when has_more is false, or when next_cursor is null for endpoints without has_more. A cursor is opaque; do not edit or reuse it with different filters.
Errors
The OpenAPI contract lists400, 401, 422, 429, 503. Error responses use error.code, error.message, and error.resolution. Narrow an expensive query after 422. Follow Retry-After after 429.
