# Errand API

> The single partner-facing API surface for expressing and executing Errands — agentic commerce on Sumvin.

The Errand API gives partners a single surface for expressing shopping intents, qualifying candidates, and executing purchases through Sumvin's agentic-commerce engine.

<Snippet file="product-term-disambiguation.mdx" />

## What it covers

Candidate qualification against a user intent, manifest assembly, and hand-off to <Tooltip headline="Errand" tip="An agent's scope-bound tasking run: Intent → Authorization → Vigilance." cta="Glossary →" href="/glossary">Errands</Tooltip> and [agent signers](/identity/agent-signers) for execution. This API is designed to be the one surface a partner integrates against rather than calling the underlying engine 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.

<Info>
  The Errand API is in private preview. Partners integrating now help shape the intent, qualification, and execution contracts before they harden — contact your account manager to co-design your Errand surface.
