Kiota

Kiota is Microsoft's open source (MIT) API client generator: a command line tool that turns any OpenAPI-described API into a strongly-typed, lightweight client in C#, Dart, Go, Java, PHP, Python, Ruby or TypeScript. It exists to remove the need to take a dependency on a different hand-written SDK for every API you call. Kiota generates only the source it needs on top of a small per-language core library, keeps external dependencies minimal, and can target a filtered subset of a large description. Beyond code SDKs it also emits agent-facing plugin packages — apiplugin for Microsoft 365 Copilot declarative agents, openai manifests, and API Manifest permission snapshots. Kiota is a consumer of API descriptions rather than a publisher of an API: there is no Kiota endpoint, base URL, API key or status page. Its surface is a CLI, runtime libraries in eight package registries, a published OpenAPI extension vocabulary, and a nine-rule description validation ruleset it runs before every generation.

Kiota publishes 1 API on the APIs.io network. Tagged areas include Code Generation, Microsoft, OpenAPI, SDK, and Developer Tools.

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

Kiota’s developer surface includes developer portal, documentation, API reference, getting-started guide, support, engineering blog, CLI, and 28 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-10-04 · rubric v0.23.0
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 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 75 points between them, because both conditional facets apply and carry 25 points together. 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/.
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/kiota: open an issue to ask a question, or submit a pull request to add artifacts.

What adopting Kiota moves on the Kin Score 4

Kiota 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 map5 features checked 2026-09-25 · rubric v0.22.0

Kiota generates typed API clients for C#, Go, Java, PHP, Python, Ruby, Swift and TypeScript, plus a shell target. Maturity ranges from stable (C#, Go, PHP, Python) to experimental. Most Kiota clients are built by API consumers inside their own code, so they never reach the provider’s surface. The score moves only when a provider publishes the clients and declares them as SDKs, or ships a shell CLI. Its pre-generation validation warnings (for example NoServerEntry) only help a contract the provider then fixes. Kiota has no docs, MCP, llms.txt or skill output.

3.0 of 3 Pre-generation validation rules
Across 8977 providers that publish a contract, adopting Kiota would move 8835. Median lift: composite +4.7 (90th percentile +4.8), agent readiness +0.0 (+0.0). Conditional rows excluded.
What Kiota ships that earns nothing (3)
  • API description search — Kiota’s search reads third-party registries. It publishes nothing about the provider and does not host an index for it.
  • Path filtering and lock file — Filtering a description produces a client for a subset of paths. It publishes no contract.
  • API client generation — The client reflects the contract and adds no idempotency key to it.

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
