Liblab

liblab generates and publishes type-safe, idiomatic SDKs in TypeScript, Python, Java, .NET, Go, PHP, and Terraform from OpenAPI/Swagger/Postman specs, plus MCP servers that expose those APIs to AI agents. The platform ships a CLI, hosted portal, and CI/CD GitHub Action that publish SDKs to customer repos via pull requests. liblab joined Postman in November 2025 to complete the API lifecycle.

Liblab publishes 4 APIs on the APIs.io network. Tagged areas include SDK, SDK Generation, Code Generation, OpenAPI, and Developer Tools.

Liblab’s developer surface includes documentation, getting-started guide, engineering blog, pricing, developer portal, signup flow, CLI, and 24 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/.

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/liblab: open an issue to ask a question, or submit a pull request to add artifacts.

liblab is an area vendor: providers adopt it to run part of their developer surface. This is the Kin Score checks its features can move for a provider that adopts it, what each one really earns, and what it earns nothing for.

sdk generationcapability map6 features checked 2026-09-25 · rubric v0.22.0

liblab lifts the SDK pointers (six languages) and, if the provider uses its docs product, the documentation and reference pointers. Each counts once declared in apis.yml. Its MCP generator deploys to liblab’s own host (mcp.liblab.io/), not the provider's, so it earns the `platform` grade (0.25) at most. Its code snippets reach only the Code Samples link fallback on openapi_examples. Spec validation, bundling and merging leave the contract's content as it was. Outside the MCP URL, liblab SDKs look like the provider's own.

Across 8977 providers that publish a contract, adopting liblab would move 8934. Median lift: composite +4.0 (90th percentile +5.9), agent readiness +2.2 (+3.5). Conditional rows excluded.

What liblab ships that earns nothing (3)

SDK and API documentation — SDK snippets in docs are not request or response examples in the OpenAPI.
Postman collection input — liblab reads a Postman collection as input. It does not publish one.
SDK code generator — SDK generation does not add an idempotency key to the contract.

A model, not a score. Adopting this vendor changes a provider's Kin Score only when the provider publishes the resulting artifacts on its own surface; nothing here writes a score, and no sponsorship or partnership can. The rating is not for sale → · Full vendor facets artifact
