Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.

  detail: The dayi35.com origin (42.157.193.96, and 42.157.193.97 for api.dayi35.com) accepts no TCP connection on port 80
    or 443 from a US vantage point — every probe returned a connection timeout rather than an HTTP status — so no live page,
    robots.txt, /.well-known/ path or spec location could be read; an October 2025 Wayback capture of the homepage shows a
    Chinese-language plastics trading portal with no developer or 开放平台 section, but that is a ten-month-old snapshot of one
    page and is not evidence about the current surface.
