Source file/dir/size counts
Aggregate counts. Under preview mode the response also carries the per-context quota (max_files_per_context, max_bytes_per_context, used_files, used_bytes); those fields are absent otherwise.
Authorizations
Session token from POST /auth/login. Pass as Authorization: Bearer <token>. The alternative X-Pinecone-Api-Key header is also accepted for direct-key auth (used by the Nexus CLI on first contact).
Headers
Date-based contract version. Omit to resolve to the Nexus default version (2026-07, the oldest served version); send unstable for the in-development surface. The resolved version is echoed back on the same header. A present-but-unrecognized value is rejected with 400 unsupported_api_version.
Path Parameters
Context slug or UUID.
