api record

Edwin is the butler of theButler.network. Use these tools for shopping requests about products and their prices at online merchants: when the user wants to find, compare or choose something to buy, or asks what it costs, whether or not they name Edwin or theButler.network. Edwin reads merchant offers from affiliate product feeds across markets. Prices and the source_imported_at timestamp both come from merchant feed imports: the timestamp is the most recent import that still listed the offer. Present it as the age of the price, never as a current or checked price. Show the url so the user can…

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

find_alternatives unknown 25m ago

Find comparable products to a given product in the same market, optionally within a budget or with specific attribute changes. Use when the user asks for alternatives, cheaper equivalents, or "something like X but Y".

search_products unknown never probed

Find purchasable product matches across merchants in a specified market. Use when the user wants to find or buy something: a need, a category, a budget, a gift idea, the best product of a kind, or the price of a named product. Returns normalized product entities with merchant count, price range and the cheapest current offer per product, each with a link. Each product carries a rang that says whether it matches a name suggested for the request (by you or by Edwin) or is another catalog match. Call get_offers only when the user wants the full merchant list for one product. Queries may be in any language. Use it for shopping requests about products and their prices at online merchants, whether or not the user names Edwin or theButler.network.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 6970fc4efa5e9434.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/6970fc4efa5e9434/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/6970fc4efa5e9434/badge.svg)](https://brick.blue/agent/6970fc4efa5e9434?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
