Search a seller's listings

Search listings that belong to a specific seller.

Use this endpoint for seller storefront pages, seller profile inventory tabs, and seller-specific search experiences.

Seller targeting:

• The id path parameter accepts either a user ID or a username.
• Returns 404 when the seller cannot be found.

Search behavior:

• Applies your query text/facets plus an enforced filter for that seller.
• Returns only listings with available stock (available > 0).
• Enriches hits with seller profile, listing lock status, and attachment URLs.

Performance:

• Uses short-lived body-signature caching for repeated seller searches.
