Locus API

Property-context APIs for agents. Buyers need no Locus or CDP account API key. Run a free coverage preflight, then pay per call for official-record reports, local-change briefs, policy and ordinance context, and environmental records. Every paid result includes source provenance, caveats, and verify-next steps. Install the Locus agent skill with `npx @velinussage/locus-agent-skill add`.
