Wegmans Marketplace Validation Agents

Each browser agent runs inside an ephemeral Vercel Sandbox running headless Chrome. Playwright drives the page navigation. Hyperbrowser provides agentic browser control where the next click depends on what the previous page rendered. The agent scrapes the marketplace product page, captures images, pricing, and promotional copy, and posts the raw observations into the validation pipeline.

Image comparison uses Scaleflex's perceptual hashing service. Unlike a cryptographic hash, a perceptual hash produces similar fingerprints for visually similar images, so a marketplace that slightly recompressed a product photo will still register as a match. The comparison returns a similarity score; the system flags only images that fall below an operator-configurable threshold.

Validation runs land in a Neon Postgres database keyed by SKU, so repeat validations skip work that has already been done and the system maintains a history of how each product has drifted over time. A second small Ollama agent synthesizes the raw findings into a business-friendly report and posts the result back through n8n to Slack or to whichever surface initiated the request.
