Atlas — Property Intelligence Platform

CE-Atlas is the property data and lead management platform. It provides property search across 12 data datasets, lead skip-tracing, divorce lead intelligence, and a credit-based billing system.

It is a separate monorepo from Cora (ce-atlas) that shares some infrastructure patterns (MongoDB, BullMQ, Chargebee, Better-Auth) but is independently deployed.

Services

Service	Port	Purpose
web	3015	Next.js 16 frontend + API routes (/api/rpc/*)
worker	3001	Express + BullMQ background job processor

The API layer (packages/api) is a set of oRPC router modules that mount inside the Next.js app at /api/rpc/*. There is no separate API server.

Core Concepts

Concept	Description
Credits	All data operations cost credits. Each user has subscription credits (reset each billing period) + purchased credits (permanent).
Datasets	BatchData exposes 12 property datasets (BASIC, OWNER, CONTACT, DEED, VALUATION, etc.). Each has its own API key and credit cost.
Lead Groups	A named list of contacts that can be uploaded via CSV and enriched (skip-traced) via the enrichment service.
Divorce Leads	Contacts sourced from public divorce filings, pre-enriched with property and party information.
Scout	A curated property discovery service with city-based permissions.
Saved Searches	Search results can be saved and re-queried.
