StartupHub.ai API
API Reference
One REST + MCP surface over millions of data points across AI startups, investors, people, funding rounds and the technology they run. Unlike Tavily, Linkup, or Parallel, we do not only search what was written about yesterday: we ingest new companies from domains and registries, then expose them as structured, filterable rows.
Quick start
Every request is a single HTTPS call with your key in the Authorization header. The base URL is https://www.startuphub.ai/api/v1.
curl "https://www.startuphub.ai/api/v1/startups?q=anthropic&limit=5" \
-H "Authorization: Bearer sk_live_your_key_here"Discovery vs web search
GET /startups answers: "show me new cybersecurity startups in Israel this month" or "Canadian AI companies we ingested this week". That requires a pre-built directory fed by domain monitors and company registries. Web-search RAG APIs answer a different question: "what did TechCrunch write about today?" Read the full comparison in the discovery guide.
