Locus Market Context
by api.locus.report in Markets & finance
Returns the same Realtor.com-on-FRED listing series and ACS home value and rent as the free route, for agents comparing a county and ZIP. Returns the same records as locus_market_context. Use this when your client can only call paid x402 routes. Use locus_market_context instead when you can call Locus free tools (REST tools/call or MCP).
