Azure Cosmos DB

Azure Cosmos DB is a fully managed, globally distributed, multi-model NoSQL and relational database service from Microsoft Azure that supports document, key-value, graph, column-family, and vector data models with turnkey global distribution, elastic scale, and SLA-backed latency, throughput, consistency, and availability. The Cosmos DB REST API exposes CRUD and query operations on databases, containers, items, stored procedures, triggers, and user-defined functions using master-key or resource-token authentication, alongside the Cosmos DB Resource Provider (Azure Resource Manager) using Microsoft Entra ID OAuth 2.0.

Azure Cosmos DB publishes 9 APIs on the APIs.io network, including Collections API, Databases API, Documents API, and 6 more. Tagged areas include Database, NoSQL, Document Database, Vector Database, and Globally Distributed.

Azure Cosmos DB’s developer surface includes authentication, documentation, pricing, signup flow, engineering blog, and 7 more developer resources.

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.

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/azure-cosmos-db: open an issue to ask a question, or submit a pull request to add artifacts.
