Lodestar Stamp

Lodestar Stamp gives Claude a dated, source-linked receipt for a local business before you book, recommend or pay it.

Ask about a Chicago restaurant and Claude can read what the City of Chicago has on file: whether the business is real and licensed, whether it operates at that address, and its health inspection history, including fails and re-inspections. Every fact carries its state (verified, claimed or not checked), the public source it came from, the date it was checked and when it expires. When the City's register shows a licence cancelled or changed, the receipt says so and cites the register row.

Coverage today: 11,208 Chicago restaurant licences, plus a pilot of 58 Chicago HVAC contractors. Look a business up by name, street address, licence number, phone or website.

What it does not do: it does not rank, rate or recommend businesses, and it does not approve or make bookings. Reviews and ratings are left out. Fields that were not checked are listed as not checked, so you know the limits before you act.

Tools (all read-only):

• find_business: search by name or street address
• get_receipt: the full receipt for one business
• batch_receipts: receipts for a shortlist of up to 20
• list_sources: the dated source behind each field
• list_gaps: the fields that are not verified
• list_markets and list_index: what is covered

Searching is open. Reading receipts needs a one-click sign-in (no account or password), which includes 10 free receipt reads a month. The connector never takes or makes payments. Receipt pages on lodestarstamp.com stay free for everyone, and payment never changes what a receipt says.
