Is tunnel-knowledge-base live?

Yes — it answered the hub's last check (checked 53m ago). It answered 99% of checks over the last 30 days.

Is tunnel-knowledge-base free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

What tools does tunnel-knowledge-base have?

10 tools: Find a local business, Check what a merchant is verified to, Ask a business one specific question, Read the answer to a question that went to a human, Read what a business charges, Read a commitment, and whether it still stands, Price a job against a business's rate card, Read one business profile, ….

Is tunnel-knowledge-base safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

• search_businesses reads unknown never probed

  Search listed businesses by name, topic or place, including merchants who have no website and are listed from their social presence. Matches words, not meanings: a business calling itself a "cofetărie" is not returned for "bakery". An empty result means "not in this index", which is not the same as "not in business". Send the query as plain text, or as a data part {"skill":"search_businesses","query":"…"}.

• check_merchant_verification reads unknown never probed

  Live verification status with the signed attestation and its position in a public hash-chained transparency log. Read the `level` field: "human" means a Tunnel employee checked legal identity, channel control and that the service is real; "automated" means machines proved only that the business controls the channels its record cites; null means neither. No level is an endorsement of quality. Send a data part {"skill":"check_merchant_verification","slug":"…"}.

• ask_business reads unknown never probed

  Answer "are they open now", "do they serve this place" or "how much notice do they need" from what the business itself authorised, with no human involved and no model in the loop. Either an answer with the fields it was read from, or an escalation. An escalation means we do not hold the fact — it is never a no, and an unlisted place in particular is "we do not know" unless the business has declared its list complete. Send a data part {"skill":"ask_business","kind":"entity","slug":"…","intent":"is_open_now"}.

• check_escalation reads unknown never probed

  When ask_business_freeform escalates, we send the question to the business on a channel they already use and give you a reference. This reads what came back. `state` is open (not sent yet), delivered (in front of them), answered (with their own words in `answer`), undeliverable (no way to reach them, so waiting will not help) or expired. It is a poll and not a subscription, and nobody is obliged to answer — come back later rather than in a loop. Send a data part {"skill":"check_escalation","ref":"…"}.

• get_rate_card reads unknown never probed

  The priced lines a business has authorised us to quote on their behalf, each with a `code`, a label, a unit and an amount. Those codes are what request_quote takes: we price exactly what you name and never work out which line a description meant, because a near-miss there is a wrong price somebody has to honour. `published` false means there is nothing to read — either they have written no card or they have not allowed prices to be named — and neither means the work is unavailable. Send a data part {"skill":"get_rate_card","kind":"entity","slug":"…"}.

  pricingquotesnon-catalog

• check_commitment reads unknown never probed

  Commitments are made with commit_order, which needs a registered agent — it is the one action here that binds a business, so it is not anonymous. This reads one back by its reference and needs no credentials. `state` is "issued" while it stands, or "repudiated" if the business has since said they cannot honour it, with their reason. A withdrawal never erases the original: both are on the signed record, timestamped. Check before acting on an old commitment. Send a data part {"skill":"check_commitment","ref":"…"}.

  commitmentsordersasynchronous

• request_quote reads unknown never probed

  Name lines from get_rate_card and we do the arithmetic. `quoted` true carries `total`, the priced `lines` and `validUntil`. A quote is a statement and not a hold: nothing is reserved, and commit_order prices the same lines again from the card at the moment it binds, so a price that changed in between is reported rather than charged. When we cannot quote — an item that is not on their card, no card at all, or a total under their own floor — the question goes to a person and you get a reference to poll with check_escalation. Send a data part {"skill":"request_quote","kind":"entity","slug":"…","items":[{"code":"…","quantity":1}]}.

  pricingquotesnon-catalog

• get_business reads unknown never probed

  Full profile for a known slug: identity, contact, social profiles, offerings, FAQ, verification level and machine-readable endpoints. Every answer states how complete it is and which wanted fields are absent — an absent field means we do not hold it, NOT that the business lacks it. Send a data part {"skill":"get_business","slug":"…"}.

• ask_business_freeform reads unknown never probed

  The same three answers, but you send the question as it was actually asked and the reply comes back in that language — en, ro, ru or de, with anything else answered in English. Prefer ask_business when you already know which question you are asking: it is instant and free, while this runs a model to read the question. That model only classifies the words and names the language; it never sees the business's stored data and never writes the reply. Read `outcome`: answered, needs_detail (we need one more thing from the asker), not_understood, or escalated — which we forward to the business ourselves and hand you an `escalation.ref` for. Send a data part {"skill":"ask_business_freeform","kind":"entity","slug":"…","question":"…"}.

• check_availability reads unknown never probed

  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 go stale. `known` true carries `days`, each with `slots` that say whether they are `free`, and `firstFree` for the earliest one. Pass a time to ask about one exact moment. `known` false means the business has not set up a calendar, which is "we cannot tell you" and never "they are busy". A free slot is not a hold. Send a data part {"skill":"check_availability","kind":"entity","slug":"…","from":"2026-08-07","days":7}.
