Object Storage Service:Data indexing fees

Last Updated:Feb 28, 2026

OSS data indexing builds custom indexes on object metadata for fast, flexible object retrieval. Indexing supports two search modes — scalar search and vector search — each billed separately.

Important
  • Both scalar search and vector search incur metadata management fees. Scalar search and vector search API calls are billed separately based on the number of requests.

  • For current prices, see OSS Pricing.
