cubic

cubic (cubic.dev) is an AI code review platform for GitHub that reviews pull requests to catch bugs and suggest improvements in complex codebases. It generates PR summaries, auto-resolves review threads once issues are fixed, learns from team feedback, enforces team coding standards through custom agents, and can generate fixes via coding agents. Developers can also run local reviews from a CLI, connect coding agents through an MCP server, and use the Members and Analytics APIs to manage seats and export pull request analytics.

cubic publishes 2 API contracts indexed on the APIs.io network: Analytics API and Organizations API. Tagged areas include Company, Artificial Intelligence, Code Review, Developer Tools, and GitHub.

The cubic catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

cubic’s developer surface includes CLI, changelog, authentication, documentation, API reference, getting-started guide, support, and 48 more developer resources.

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 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):

Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too Ask about this →
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service, OR (0.27) a live x402 payment challenge from _data/x402-adoption.json — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's Ask about this →
