    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    No publisher quote has been checked.

    Every tool description is at least 20 characters.

Capabilities

Tools 12

create_business_listing

Submits a business to a town's directory, on the same rails as create_event_listing: screened inside the call, approved paid submissions come back with a hosted payment URL. CHARGES NOTHING — a person must open the URL and enter card details. A paid listing runs for 30 days starting the day payment clears; a free (`standard`) one publishes only if a person approves it. Call get_listing_prices first.

Discovered
create_event_listing

Submits an event to a town's calendar. The compliance screen runs inside this call: an approved paid submission comes back with a hosted payment URL, a rejected one comes back with a reason and no charge was ever possible. CHARGES NOTHING — a person must open the URL and enter card details. Nothing published here publishes itself: a paid listing goes live only after payment is confirmed, a free (`standard`) one only after a person approves it. Call get_listing_prices first.

Discovered
get_archive

Returns the markdown body of a past newsletter edition for a city. Defaults to the most recent edition.

Discovered
get_city

Returns city details: subscriber count, recent archive list, and Census Bureau demographics.

Discovered
get_listing_order

Whether a listing order has been paid and whether the listing is live yet. Possession of the order id is the credential, so the answer carries order state and public listing fields only — never the buyer's name or address. Read-only.

Discovered
get_listing_prices

What it costs to list an event or a business in one town, and whether that town is currently selling. Call this before create_event_listing or create_business_listing. Read-only.

Discovered
get_town_quote

Check whether a U.S. town can be leased as a MailerDot operator, and what it costs per month. Pricing is by subscriber count: $10/month covers the first 1,000 subscribers, then +$5 per additional 1,000. Read-only — this reserves nothing.

Discovered
get_weather

Returns today's weather for a city (snapshot from the newsletter, or live from Open-Meteo).

Discovered
list_cities

Returns every U.S. city with an active MailerDot newsletter, grouped by state.

Discovered
search_archives

Full-text search across all past newsletter editions. Returns ranked matches with snippets.

Discovered
start_town_checkout

Starts an operator checkout for a town and returns a hosted payment URL. CHARGES NOTHING: a person must open the URL and enter card details before anything is bought, and the email they enter there becomes the operator account. The town is held for a short reservation window and released if the checkout is not completed. Call get_town_quote first to confirm availability and price.

Discovered
subscribe_city

Subscribes an email address to one city's free daily digest. A welcome email goes out at once and the first edition is generated and sent within minutes; every edition carries a one-click unsubscribe. Free, no account. This sends mail to the address given — only call it for an address whose owner asked to subscribe, and confirm with them first. An address can hold up to 10 city digests; subscribing to a second city adds it, never replaces the first.
