Linkup — DEEP agentic search
Linkup — DEEP agentic search: iterative multi-query retrieval for hard or multi-hop questions where one-pass search misses. Same params as linkup/search (`q` + outputType/dates/domain filters). Slower (tens of seconds) and 5× the price — escalate here only after linkup/search or exa/search come back thin. For full multi-step research reports, parallel/task (10-30¢) is the bigger rung.
