ADF/XML to your CRM

Enroll and connect your feed

Submit your dealership details and feed URL — FTP CSV for automotive, Lightspeed API for powersports. LotCast syncs your inventory automatically every night, keeping listings current without any ongoing effort from your team.

AI agents discover your inventory

When a buyer asks an AI assistant to find a vehicle, LotCast returns your live inventory — make, model, year, price, availability, photos, and distance from the buyer. Your vehicles surface alongside every enrolled dealer, ranked by proximity and relevance.

Leads land in your inbox

When a buyer is ready, they submit a lead through the AI agent. LotCast delivers it instantly in ADF/XML or plain text — the same format your CRM already accepts. No new software, no portal to check.
