search_businessesFind businesses, merchants and websites in the tunnel knowledge base by name or topic. Start here: every other tool needs a `slug`, and this is where a `slug` comes from. Returns an array of summaries, each with `slug`, `kind`, name, description and a `verification` object. Read…
get_businessRead the full profile of one business. Returns identity, contact details, address, social profiles, offerings, FAQ, `verification` and any machine-readable endpoints we publish for it. Absent information is named in `missing` rather than dropped silently, so an empty field means…
check_merchant_verificationCheck live what a merchant has actually been verified to, and by whom. Call this before acting on a claim that matters — a profile is a cached summary, this is the current answer. Returns `level`, a signed attestation, an expiry date and the transparency-log position. `level` "h…
ask_businessAsk one specific question about a listing and get an answer from the registry, with no human involved. Try this before contact_business: it is instant, free, and does not put a message in someone's inbox. Returns either an answer or an escalation. When `resolved` is true, `answe…
ask_business_freeformSame answers as ask_business, but you send the person's own words instead of choosing an intent, and the reply comes back in the language they used. Supported languages: en, ro, ru, de; anything else is answered in English. Prefer ask_business when you already know which of the…
check_escalationRead the answer to a question that had to go to a human. Use the `escalation.ref` that ask_business_freeform returned when its outcome was "escalated". Returns a `state` and, once there is one, the business's own `answer` in their words. Branch on `state`: "open" means we have n…
check_commitmentRead a commitment you were given by commit_order, including whether the business has since withdrawn it. Returns `state`: "issued" means it stands, "repudiated" means the business said they cannot honour it, with their stated reason. A withdrawal does not erase the original — bo…
get_rate_cardRead the prices a business has authorised us to quote on their behalf. Returns `published` and, when true, a `rateCard` holding a currency, an optional minimum charge and `items` — each with a `code`, a label, a unit and an amount. Those `code` values are what request_quote and…
request_quotePrice a specific set of line items against a business's rate card. Call get_rate_card first and name `code` values from it; we do the arithmetic. Returns `quoted`. When true you get `total`, `lines` showing what each one came to, and `validUntil`. A quote is a statement, NOT a h…
check_availabilityFind out when a business is actually free. Worked out per call against their opening hours, their notice period, their blackout dates and what is already booked — there is no stored list of free times to be out of date. Returns `known` true with `days`, each holding `slots` that…
commit_orderPlace a binding order with a business, inside limits they set in advance. This is the only tool here that commits anyone to anything. Either name the figure yourself, or send `items` from get_rate_card and we price them from the merchant's own card. Either way it is checked agai…
cancel_orderCancel an order you placed with commit_order. Returns `settled`. True means it is cancelled, the business has been told and their day is free again. False comes with a `reason`: "inside-cancel-window" (later notice than they said they need), "no-cancel-window-set" (they never sa…
reschedule_orderMove an order you placed to a different date, or a booking to a different slot. The price, the items and the quantity are unchanged — this moves WHEN, nothing else. To change what was ordered, use request_order_change. A booking made for a time must be moved to a time, and a who…
request_order_changeRaise anything else about an order that already exists: a change to what was ordered, a refund request, or a problem with what was delivered. This tool never settles anything, and that is deliberate. Changing an order re-prices it and a refund moves money tunnel does not hold, s…
contact_businessOpen a conversation with the person behind a listing. The message arrives in their dashboard inbox and they reply when they get to it — this is asynchronous, not a chat, and nobody is obliged to answer. Returns a `conversation_id` and a secret `token`. Keep both: they are the on…
check_repliesRead a conversation you opened with contact_business, including anything the business has replied since. Returns the whole message thread and its status. Poll it; there is no push. Authentication: the `conversation_id` and `token` from contact_business are the credential for thi…
send_followupAdd another message to a conversation already opened with contact_business. Returns the updated message thread. There is a cap on messages per conversation, so send one considered follow-up rather than several fragments. Authentication: bearer token required — the same one used…
