## Inventory identifiers
Every listing requires a Part #. Use the exact `part_number` field when matching or purchasing a component.

## Live machine-readable catalog
GET https://qvrvjmktcdjskvojhqpd.supabase.co/functions/v1/agent-commerce

Optional query parameters:
- `q`: free-text search across title, Part #, category, description and location
- `part_number`: exact Part # lookup

Only approved listings are returned. Check the live catalog immediately before purchase for stock and availability.

## Agent checkout

Content-Type: application/json

Create checkout:
{"action":"checkout","listing_id":"UUID_FROM_CATALOG","buyer_email":"buyer@example.com"}

The response returns a secure Stripe Checkout URL plus `order_id` and `session_id`. External-store listings return their source-store URL instead.
