OpenSearch

OpenSearch is the open source, community-driven search, analytics, and observability suite (forked from Elasticsearch and Kibana) maintained under the Linux Foundation's OpenSearch Software Foundation. The platform exposes REST APIs across the search engine, the OpenSearch Dashboards UI, and a set of plugins. The Security plugin REST API lets administrators programmatically create and manage internal users, roles, role mappings, action groups, tenants, security configuration, audit log configuration, and SSL certificates.

OpenSearch publishes 14 APIs on the APIs.io network, including Account API, Action Groups API, Allowlist API, and 11 more. Tagged areas include Search, Analytics, Observability, Open-Source, and Security.

The OpenSearch catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

OpenSearch’s developer surface includes authentication, developer portal, documentation, getting-started guide, engineering blog, and 15 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/opensearch: open an issue to ask a question, or submit a pull request to add artifacts.
