# Unsupported Artifact Types An artifact is defined as something that is produced by a process or protocol step. It is the output of a process/protocol step run in Clarity LIMS. For example, analytes and result files are all artifacts. Currently, the REST API does not support the following artifacts: * **Reagents**—While reagents are produced by some processes in the Clarity LIMS client, they are not exposed as artifacts in the REST API. Reagents are an entity type of their own available through the list and single reagents resources. * **Subartifacts**—When a process produces shared outputs, the system creates subartifacts to support the REST data model. While they exist as entities in the system, subartifacts are transparent and meaningless to a user and are therefore not supported. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://help.connected.illumina.com/clarity-lims/api-and-database/api-docs/application-examples/resources-and-references/unsupported-artifact-types.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
