Elasticsearch

Elasticsearch is an open source search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured. It provides a RESTful API for indexing, searching, and managing data, with powerful aggregation capabilities and real-time analytics at scale.

Elasticsearch publishes 5 APIs on the APIs.io network, including Cat API, Cluster API, Document API, and 2 more. Tagged areas include Analytics, Database, Full-Text Search, NoSQL, and Search.

Elasticsearch’s developer surface includes changelog, CLI, authentication, documentation, getting-started guide, engineering blog, pricing, and 30 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/elasticsearch: open an issue to ask a question, or submit a pull request to add artifacts.

Arazzo Workflows 8

Multi-step API workflows described with the Arazzo specification.

Elasticsearch Bulk Load and Verify

Check the cluster can take writes, push an NDJSON bulk payload, verify the resulting document count, and inspect the index.

ARAZZO

Elasticsearch Cluster Health Triage

Walk cluster health, the cat health and nodes views, cluster stats, and cluster state to triage a degraded cluster.

ARAZZO

Elasticsearch Document Lifecycle

Index a document by id, read it back, apply a partial update, and confirm the merged result.

ARAZZO

Elasticsearch Purge a Document by Business Key

Locate a document by a business key, delete it by its internal id, and prove it is no longer retrievable or searchable.

ARAZZO

Elasticsearch Bootstrap an Index

Check the cluster is ready, create an index only if it does not already exist, and read back its settings and mappings.

ARAZZO

Elasticsearch Tear Down an Index

Confirm an index exists, capture its definition for the record, delete it, and verify it is gone.

ARAZZO

Elasticsearch Search and Fetch the Top Hit

Run a quick URI search to size a result set, re-run it as a paged DSL query, and fetch the full source of the top hit.

ARAZZO

Elasticsearch Upsert a Document by Business Key

Search an index for a document matching a business key and update it if found, otherwise index a new one.
