Apicurio Registry is a datastore for standard event schemas and API designs. Apicurio Registry enables developers to manage and share the structure of their data using a REST interface. For example, client applications can dynamically push or pull the latest updates to or from the registry without needing to redeploy. Apicurio Registry also enables developers to create rules that govern how registry content can evolve over time. For example, this includes rules for content validation and version compatibility.
The Apicurio Registry REST API enables client applications to manage the artifacts in the registry. This API provides create, read, update, and delete operations for schema and API artifacts, rules, versions, and metadata.
The supported artifact types include:
Apache Avro schema
AsyncAPI specification
Google protocol buffers
GraphQL schema
JSON Schema
Kafka Connect schema
OpenAPI specification
Web Services Description Language
XML Schema Definition
Important: The Apicurio Registry REST API is available from https://MY-REGISTRY-URL/apis/registry/v2 by default. Therefore you must prefix all API operation paths with ../apis/registry/v2 in this case. For example: ../apis/registry/v2/ids/globalIds/{globalId}.

This API provides a standard for US and international cities for the purposes of standardizing city name data, improving query results, analytics, and data merging.

Code against the Bitbucket API to automate simple tasks, embed Bitbucket data into your own site, build mobile or desktop apps, or even add custom UI add-ons into Bitbucket itself using the Connect framework.

This API provides a similarity key used to match with other similar company name data, including for purposes of deduplication, fuzzy matching, or merging of datasets. A much higher match rate will be achieved by matching on the algorithmically generated similarity key rather than the data itself.
