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.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
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/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/dayi35-com: open an issue to ask a question, or submit a pull request to add artifacts.

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.
