You have the following option: Use the full path to the artifact content URI and add the parameter describe=info

For example:

https://repository.sonatype.org/service/local/repositories/maven-sites/content/nexus-oss/css/maven-theme.css?describe=info

Returns an ArtifactInfoResourceResponse, which is an XML that contains the artifact size in KB:

<org.sonatype.nexus.rest.model.ArtifactInfoResourceResponse>
  <data>
    <presentLocally>true</presentLocally>
    <repositoryId>maven-sites</repositoryId>
    <repositoryName>maven-sites</repositoryName>
    <repositoryPath>/nexus-oss/css/maven-theme.css</repositoryPath>
    <mimeType>text/css</mimeType>
    <uploader>grid</uploader>
    <uploaded>1324414832000</uploaded>
    <lastChanged>1324414832000</lastChanged>
    <size>2801</size>
    <sha1Hash>f773e0309d4c0f7aab4aac0ec3ae50088ad02394</sha1Hash>
    <md5Hash>61d12a98b59a0fefcc3b0ed8313239de</md5Hash>
    <repositories>
      <org.sonatype.nexus.rest.model.RepositoryUrlResource>
        <repositoryId>maven-sites</repositoryId>
        <repositoryName>maven-sites</repositoryName>
        <path>/nexus-oss/css/maven-theme.css</path>
        <artifactUrl>https://repository.sonatype.org/content/repositories/maven-sites/nexus-oss/css/maven-theme.css</artifactUrl>
