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
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.
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.

4.0 of 4 | API client generation |
| At least one SDK Developer ErgonomicsPublish a generated client as a maintained package and declare it as an SDK entry. A client a consumer generates inside its own app never counts. |

3.0 of 3 | shell language target |
| Real servers declaredconditional Contract QualityNoServerEntry only warns. The provider has to add a real host to the published contract, and the API has to have one. |

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
