Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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/flash-express: open an issue to ask a question, or submit a pull request to add artifacts.

  description: The FlashExpress Open API is the merchant-facing integration surface for Flash Express parcel logistics in
    Thailand. All calls are HTTPS POST with an application/x-www-form-urlencoded body and a JSON response envelope of code/message/data.
    Every request is authenticated with a merchant id (mchId), a random nonce string (nonceStr) and an uppercase SHA256 signature
    (sign) computed over the ASCII-sorted non-empty parameters joined with a merchant secret key issued by Flash Express support.
    The API covers warehouse listing, the Flash standard address/location tree, sub-account creation, order creation (including
    creation against a merchant-supplied tracking number), order modification and cancellation, single and batch parcel route
    tracking, delivered-proof retrieval, 100x180mm and 100x75mm label pre-print, freight-rate estimation, courier pickup notification
    scheduling and cancellation, and webhook subscription management.
