Tools

ask_business ~432 tokens
Ask 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, `answer` holds it and `basi
ask_business_freeform ~666 tokens
Same 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 three questions you a
cancel_order ~396 tokens
Cancel 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 said), "order-passed",
check_availability ~469 tokens
Find 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their notice period, their blackout dates and what is already booked — there is no stored list of free times to be out of date.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 carry a start, an en
check_commitment ~191 tokens
Read a commitment you were given by commit_order, including whether the business has since withdrawn it.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 — both are on the record,
check_escalation ~302 tokens
Read 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 not reached them yet,
check_merchant_verification ~296 tokens
Check 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` "human" means a tunnel
check_replies ~182 tokens
Read 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 this call. No bearer tok
commit_order ~990 tokens
Place 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 against their price floor
contact_business ~466 tokens
Open 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 only way to read a repl
get_business ~241 tokens
Read 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 "we do not hold this
get_rate_card ~329 tokens
Read 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 commit_order take: we
request_order_change ~434 tokens
Raise 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, so both are decisions
request_quote ~572 tokens
Price 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 hold — nothing is rese
reschedule_order ~472 tokens
Move 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 whole-day order to a who
search_businesses ~428 tokens
Find 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 `verification.level`
send_followup Sends messages · ~226 tokens
Add 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 for contact_business
