Create You.com ResearchYOUSEARCH_CREATE_RESEARCH
Run cited multi-step You.com research synchronously or create a background task. Synchronous and background submissions share the documented 10 requests/second limit; You.com does not publish a separate background-task concurrency cap. Effort pricing and typical latency per 1,000 calls are: lite $12 and <10s; standard $50 and about 10-30s; deep $100 and <120s; exhaustive $450 and <300s; frontier $1,200 and 30-12000s (p50 300s). Background mode supports deep, exhaustive, and frontier only, and is mandatory for frontier. Structured output supports arbitrary schemas within a restricted subset: object root, depth 5, 100 properties, 500 enum values, 7,500 large-enum string characters, and 25,000 total schema-string characters; all object properties must be required and additionalProperties must be false. Structured output is unavailable with lite.
