Query partial standardized funding observations.
GET
Funding Rates
Read funding-bearing ticker observations in global collector-time order. Fields absent from a venue observation remain null; do not carry earlier values forward as if they were published again.

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
funding_rate, predicted_funding_rate, premium, mark_price, index_price, and open_interest are nullable decimal strings. /perpetual-ticker currently returns the same funding-bearing observations. SDK funding series have a separate point shape; see funding series.
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.
