Shopify Agent Data – Full-Text Product Search

Use this endpoint when you need to search for specific products across multiple Shopify stores simultaneously using keyword or full-text search. Prefer this over a single-store API when you want broad coverage across the Shopify ecosystem rather than querying one merchant directly.

• No products found matching the query — empty result set returned
• Query too vague or common — returns too many unfiltered results
• Store not indexed — products from untracked stores won't appear
• Rate limit or payment failure — call rejected due to missing or failed x402 payment
• Malformed query string — 400 bad request error
