!!! info "ApiFundingRateRequest" Lookup the historical funding rate of a perpetual future.

Pagination works as follows:

• We perform a reverse chronological lookup, starting from end_time. If end_time is not set, we start from the most recent data.
• The lookup is limited to limit records. If more data is requested, the response will contain a next cursor for you to query the next page.
• If a cursor is provided, it will be used to fetch results from that point onwards.
• Pagination will continue until the start_time is reached. If start_time is not set, pagination will continue as far back as our data retention policy allows.
