Logicstar

LogicStar is an AI platform for autonomous software maintenance. Its AI agent investigates, reproduces, and fixes real bugs from a development team's backlog: it reproduces each bug with a failing test that proves the issue is real, then validates that a proposed fix actually resolves it before opening a pull request, keeping a human in the loop for review. LogicStar connects to a team's stack through integrations such as GitLab and Sentry rather than a public developer API. Founded in 2024 in Zurich by Boris Paskalev, Veselin Raychev, Mark Mueller, and Prof. Dr. Martin Vechev — the team behind DeepCode.ai (acquired by Snyk, now Snyk Code) and a spin-out of INSAIT/ETH Zurich — and backed by Northzone. As of this writing the product is in alpha with design partners and supports Python, with TypeScript, JavaScript, and Java support announced as coming soon.

Logicstar is profiled on the APIs.io network. Tagged areas include Company, Enterprise, Artificial Intelligence, AI Agents, and Software Maintenance.

Logicstar’s developer surface includes documentation, getting-started guide, engineering blog, pricing, signup flow, support, and 12 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 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/.

Raise your score.

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

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
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
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
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

13 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 0.0 — up to +25.0 composite points
Operational Transparency scores 2.6 — up to +12.7 composite points
Developer Ergonomics scores 38.1 — up to +12.4 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/logicstar/apis.yml: open an issue on github.com/api-evangelist/logicstar to ask a question or point us at an artifact you publish.
