🔍 Web Search API

Launch web searches through /v1/tools/search and /v1/tools/search_pro and get structured results — ideal for Agent applications that orchestrate their own search logic. Organization- and project-level QPS limits are supported. See Web Search Basic, Web Search Pro, Web Search Best Practices, and Web Search Pricing.

💰 Billing method change

Account usage is now deducted at a uniform ratio of 50% cash and 50% vouchers. When either balance is depleted, all subsequent usage is deducted from the remaining balance type. Users with signed contracts follow their contract terms and continue to prioritize voucher usage — they are not affected.
  • The kimi-k2.5 and all moonshot-v1 series models (including -vision-preview and moonshot-v1-auto) were retired across all platforms. Calls to these models now return a 404 “model not found” error. Please migrate to Kimi K3.
  • Files API updates: newly generated file IDs now carry the file_ prefix; improved parsing of complex content such as tables and formulas; images are no longer OCR’d for text extraction (for image understanding, upload images with purpose=image; see Use Vision Models); files uploaded with the same name as an existing file are automatically renamed by the server.
