Landbase is a Palo Alto, California go-to-market (GTM) data and agentic-AI company whose platform builds, qualifies, enriches and activates B2B audiences from natural-language requests. Its GTM-1/GTM-2 Omni models sit behind a B2B database of 300M+ contacts with 1,500+ enrichment fields, an agentic search surface, lookalike expansion, AI lead qualification, and email/LinkedIn outbound campaign execution. Landbase's programmable surface is deliberately agent-first rather than REST-first: the documented client is `landbase-cli`, a self-updating binary distributed from cli.landbase.com that talks to the cloud gateway at api.landbase.com, returns JSON on stdout and stable error codes on stderr, and ships a library of provider-authored Agent Skills for Claude Code and Codex. No OpenAPI description of the gateway is published; the gateway itself sits behind a Cloudflare bot challenge on every path except /.well-known/.
