Shopify Public Catalog Search
Search a live public Shopify storefront and return current public products, variants, prices, availability, images, and declared agent-commerce capabilities.
Preview request
The preview path is rate-limited and does not charge. Production requests use the same parameters and return a standard x402 challenge when no payment signature is present.

Example deliverable
This is the documented response shape, not a promise that live values will match the example. The paid request returns current or declared-source results using the same contract.

}Purchase decision
Buy when: the active task needs this product's structured result, its declared source and freshness are sufficient, and 0.01 USDC is within the buyer's authorized per-request limit.
Skip when: a cached result is sufficient, the source or fields do not satisfy the task, or the buyer has not authorized payment. Do not bypass wallet, budget, or user-approval policy.
Guaranteed response metadata
Every successful product response identifies how the result was produced. Product-specific output fields are documented in the paid OpenAPI contract and can be inspected through the preview request where available.

"marketplace_metadata": {
"data_mode": "live_source",
"billable": true,

}
}Agent payment flow
Fast path: install the public MCP package, configure a dedicated low-balance Base buyer wallet and a maximum per-request spend, then call this tool with auto_pay: true. The client handles the challenge, local signature, settlement, and retry in one tool call.
