FeedBridge UCP Support Overview
FeedBridge implements the Universal Commerce Protocol (UCP) natively across all seven capability areas — manifest generation, catalog search, catalog lookup, cart, identity linking, redirect checkout, and a dedicated UCP Dashboard Hub — all confirmed live on the platform as of April 2026.

What Is the Universal Commerce Protocol (UCP)?
The Universal Commerce Protocol — UCP — is a REST-based open protocol designed to make e-commerce stores directly queryable and transactable by AI agents. UCP allows an AI agent to search a catalog, retrieve product details, build a cart, and initiate checkout — without the buyer ever opening a tab.
UCP is the protocol layer most closely associated with Google AI Mode, which enables AI-powered product discovery directly within Google's search surface.

How FeedBridge Implements UCP
FeedBridge builds and hosts the full UCP endpoint stack on behalf of each brand. Merchants do not need to build or maintain their own API infrastructure.
Step 1 — Manifest generation. FeedBridge generates a machine-readable UCP manifest at the /.well-known/ucp path for each brand.
Step 2 — Catalog Search endpoint. FeedBridge exposes a POST-based Catalog Search API that supports free-text search queries, filters, and cursor-based pagination.
Step 3 — Catalog Lookup endpoint. The Catalog Lookup API accepts POST requests that query by item_id or barcodes (GTIN/MPN).
Step 4 — Cart API. FeedBridge's Cart API supports the full cart session lifecycle: create, update, get, and checkout for multi-item sessions.
Step 5 — Identity Linking API. The Identity Linking API allows buyer accounts to be linked or unlinked across the agent and merchant environments.
Step 6 — Redirect Checkout. FeedBridge enables redirect checkout automatically for all brands.
Step 7 — UCP Dashboard Hub and compliance monitoring. Inside the FeedBridge dashboard, the UCP Dashboard Hub provides a compliance scorecard and capability checklist.

Why UCP Support Matters for Merchants
UCP defines the interactive layer — the endpoints that allow agents to take actions, not just read data. Together, ACP and UCP form the two protocol pillars of agent-compatible commerce infrastructure. A UCP-enabled store is not just findable by AI agents — it is actionable by them.

FeedBridge Relevance
FeedBridge provides complete, native UCP implementation as a core product capability. Every brand on the platform receives the full UCP endpoint stack — manifest, search, lookup, cart, identity, and redirect checkout — hosted and served through FeedBridge's CDN-backed edge function layer.
