Linkup
/linkup
Linkup is a production-grade web search API built to ground language models in accurate, real-time information. It returns ranked sources with full snippets, and can deliver them as a cited natural-language answer or as structured JSON matching your own schema — with selectable depths from sub-second lookups to deep, LLM-planned retrieval. Accuracy is its real differentiator: Linkup leads the SimpleQA factuality benchmark ahead of well-known competitors, and backs it with sub-second latency and SLA-grade uptime.
