Hello, I checked the public OpenAPI specification and would like to confirm whether your documented APIs support historical Douyin e-commerce creator metrics for a specified 30-day period.

1. Is there an endpoint for the Compass metric “实际签收金额” (actual signed-for / received order amount), with daily records? This must be distinguished from payment GMV, estimated sales and estimated settlement amount. Please identify the original source and the date attribution rule (order date versus receipt date).
2. Is daily sales quantity available? Please specify whether this is paid units, received units, or order count.
3. Are daily live-commerce traffic-source shares available, including organic and paid sources? Please identify the denominator (viewers, visits, impressions, or transactions) and whether the classification includes Qianchuan/paid promotion.
4. Are aggregate follower, live-viewer and purchaser demographics available as distinct datasets, including gender, age and region? What time window does each dataset cover?
5. For each supported metric, please provide the documented endpoint, original-source definition, access/creator-authorization requirements, and any free test or anonymized response sample. We are not requesting credentials, a login bypass or access to a creator's private backend.

If these metrics are not supported, please state that explicitly; public video engagement statistics, fixed demo responses and estimated GMV would not meet this request.

Thank you.
