The Unified Shopping API will give partners a single surface for expressing shopping intents, qualifying candidates, and executing purchases through Sumvin’s agentic commerce stack. It is backed by the Abstract Commerce engine.

​
What it covers

Candidate qualification against a user intent, manifest assembly, and hand-off to IPAs and agent signers for execution. The surface is designed to be the one API a partner integrates against rather than calling the Abstract Commerce internals directly.

​
Who it’s for

App developers building agentic commerce experiences on Sumvin, and merchants who want structured intent-to-purchase flows instead of bespoke search-plus-checkout integrations.
The Unified Shopping API is in early access. Partners integrating now help shape the intent, qualification, and execution contracts before they harden — contact your account manager to co-design your agentic commerce surface.

​
Where to start

  1. Agentic commerce overview — how the stack is composed.
  2. IPA lifecycle — how a shopping intent becomes an executed action.
  3. Agent signers — the P-256 keys that sign on a user’s behalf.
  4. Perpetual search quickstart — stand up a long-running shopping agent.
