Clerk.io API is one of 2 APIs that [Clerk.io](https://apis.io/providers/clerk-io/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Commerce, Personalization, Recommendations, and Search. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, a getting-started guide, and authentication docs.

The Clerk.io API provides REST endpoints for managing products, categories, orders, customers, recommendations, and search. The API uses a dual-key authentication model: a public key identifies the store and is used in browser-side requests, while a private key is required for sensitive operations and data ingestion. JSON is the primary payload format and SSL is required when sending the private key. Clerk.io publishes an OpenAPI 3.1.0 definition of 65 paths and 101 operations through its ReadMe developer portal, covering catalog ingestion, search, twenty-five recommendation logics, behavioural logging, merchandising, audiences and GDPR privacy requests.
