Piazza

Piazza is an online question-and-answer platform for higher education that connects students, teaching assistants, and professors in a single wiki-style collaborative space for each class. Instructors run a Piazza for their course where students ask and answer questions, post anonymously, use a LaTeX and code editor for technical content, and receive instructor-endorsed answers. Piazza integrates with every major learning management system (Canvas, Blackboard, Moodle, Sakai, Desire2Learn, and others) via the LTI standard for single-click class creation, roster-based automatic enrollment, and automatic single sign-on. It is used across thousands of universities in more than 90 countries and is FERPA-compliant. Piazza does not publish an official public developer API; LMS connectivity is delivered through LTI, and only community projects wrap its internal endpoints.

Piazza is profiled on the APIs.io network. Tagged areas include Company, Consumer, Education, EdTech, and Q&A.

Piazza’s developer surface includes engineering blog, support, and 5 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Education & Research 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/piazza: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Workplace Collaboration App Marketplaces	standard	40.9 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

LTI

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
