Pathmind

Pathmind (formerly Skymind, the company behind the Deeplearning4j open-source deep learning library) was a San Francisco reinforcement-learning company that let simulation engineers train RL policies against AnyLogic and Python simulations without writing machine-learning code. The product had three parts: the Pathmind Helper, an AnyLogic palette item that exposed a simulation's observations, actions and reward function to Pathmind; a cloud training service where uploaded models became experiments; and Pathmind Serving, a FastAPI/Ray policy server that turned a trained policy into a REST prediction endpoint. A small first-party REST API (project listing and AnyLogic model upload, authenticated with an X-PM-API-TOKEN header) and a first-party Python simulation API on PyPI were published. Pathmind ceased operating in November 2021 — its own final release, pathmind-webapp v1.8.6, is titled "Final release - disabling sign-ups and upgrades" — and the app, API and marketing hosts no longer serve. The artifacts in this repository are the surviving public first-party surface, harvested from the company's own GitHub organization and PyPI.

Pathmind publishes 2 API contracts indexed on the APIs.io network: Model Upload API and Projects API. Tagged areas include Company, Artificial Intelligence, Machine Learning, Reinforcement Learning, and Simulation.

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

Pathmind’s developer surface includes documentation, API reference, changelog, and 16 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.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against 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 65 points between them, because both conditional facets apply and carry 35 points together. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 65% 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)
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)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

9 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
Developer Ergonomics scores 0.0 — up to +20.0 composite points
Access Clarity scores 0.0 — up to +20.0 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.
