CodeCombat

CodeCombat is a game-based computer science platform where students learn to code by playing a real programming game, writing Python or JavaScript to control heroes through levels. Its Partner API (a Fern-generated REST API at https://codecombat.com/api, secured with HTTP Basic authentication) lets learning platforms and school districts provision and manage users, create and administer classrooms, enroll students in courses, grant and shorten licenses and Home subscriptions, link OAuth2 SSO identities, manage clans, and pull playtime, license, and per-member progress statistics. CodeCombat is backed by a16z and Y Combinator and publishes official Node, Python, Java, and Go SDKs plus a Postman collection generated from its public OpenAPI description.

CodeCombat publishes 5 API contracts indexed on the APIs.io network, including Auth API, Clans API, Classrooms API, and 2 more. Tagged areas include Company, Education, EdTech, Coding, and Learning.

The CodeCombat catalog on APIs.io includes 1 Spectral governance ruleset.

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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

11 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Access Clarity scores 21.1 — up to +15.8 composite points
Developer Ergonomics scores 25.6 — up to +14.9 composite points
Contract Quality scores 46.0 — up to +13.5 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/codecombat/apis.yml: open an issue on github.com/api-evangelist/codecombat to ask a question or point us at an artifact you publish.
