List the Websites at One Network Address or BuiltWith Tag (BuiltWith)
List the websites seen at one network address, or carrying one BuiltWith tag, with the window each was observed. Supply the address in the provider's own form, such as IP-151.101.1.195, or a tag string — a domain is not a valid input here and comes back empty. These are the neighbours sharing an address, not a reading of what any one website runs. One address or tag per request, not a range of addresses.

}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 /tag1/api.json on Glasser with input {"LOOKUP":"IP-151.101.1.195"}glasser run -p builtwith -e '/tag1/api.json' -i '{"LOOKUP":"IP-151.101.1.195"}' --endpoint-version 1Pinned to version 1, 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":"/tag1/api.json","input":{"LOOKUP":"IP-151.101.1.195"},"endpoint_version":1}'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 1 for the same reason as the CLI.
