Collection infrastructure
External workers fetch queue tasks and submit results through an authenticated API. A separate browser service reuses browser processes, isolates request contexts and limits concurrent work.
Application and data
The FastAPI backend manages products, regional pricing, historical observations and alert rules. SQLAlchemy persistence supports separate read and write engines; the deployment stack includes PostgreSQL and connection pooling.
Commercial operations
Accounts, credits, payment integrations and recipient verification sit alongside the monitoring engine. Price events trigger alert evaluation and delivery through configured notification channels.
