Count Stack Components by Group for One Website (BuiltWith)
Count how many technologies a website runs in each stack group — framework, hosting, analytics, commerce and the rest — given its domain. Each group row carries a live count and a retired count, plus the dates the website was first and last indexed. Group counts only: the component names themselves never come back. Free.

}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 BuiltWith Endpoint /free1/api.json on Glasser with input {"LOOKUP":"shopify.com"}glasser run -p builtwith -e '/free1/api.json' -i '{"LOOKUP":"shopify.com"}' --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":"builtwith","endpoint":"/free1/api.json","input":{"LOOKUP":"shopify.com"},"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.
