Provided by Serper
Search Products and Their Prices Across Merchants (Serper)
Search Google Shopping for a product: every listing carries the product title, the seller, the price, a rating and a link to the offer. Supply a query phrase, and optionally a country code (gl) and a language code (hl). One page of listings per call, and the prices come from many merchants at once rather than from one store catalogue.

}This Endpoint publishes no output schema. You get the Provider's own response body, unchanged — we do not warrant a shape we cannot guarantee.
How to run it
Two fields identify it: the Provider and the endpoint key. The key looks like a path because it usually mirrors the Provider's own, but it is an opaque identifier — not a URL you can open. The same provider:endpoint pair is what your Policy lists.
Once: paste this into your agent's chat. The Skill installs the CLI and logs in by itself. For an agent that cannot use a shell, connect it over MCP instead.
set up https://glasser.ai/SKILL.mdThen ask for this Endpoint:
Run the Serper Endpoint /shopping on Glasser with input {"q":"mechanical keyboard low profile"}glasser run -p serper -e '/shopping' -i '{"q":"mechanical keyboard low profile"}' --endpoint-version 2Pinned to version 2, the one this page shows: if a newer version is published first, the Run is refused instead of charged under new terms. Install and log in first on Get Started.
Once per Run:
IDEMPOTENCY_KEY=$(uuidgen)Run it, and copy this same block to send it again:
curl -X POST https://api.glasser.ai/v1/runs \
-H "Authorization: Bearer gl_..." \
-H "Idempotency-Key: $IDEMPOTENCY_KEY" \
-H "Content-Type: application/json" \
-d '{"provider":"serper","endpoint":"/shopping","input":{"q":"mechanical keyboard low profile"},"endpoint_version":2}'Reuse the same Idempotency-Key to send it again: the second send is a read of the first Run. A new key is a new Run and a new Charge. Pinned to version 2 for the same reason as the CLI.
