  • 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.

Capabilities

Tools 16

ask_business

Send your person's question to a business's own inbox: only for a listed business with an inbox, and only when your person asked you to contact it. The business answers your person by email, at the address they agreed to give (consent), never by phone. Keep the access_token for your person: it reads the request's state.

Discovered
check_business

Check what an AI agent can do on a business's website (message, book, order, sign up, pay, change or cancel), and its agentic score. Waits up to 25 seconds; if the read is not done, call again for the score. Set fresh after the site changed. Use it when a person asks how agent-ready a business is, or wants to improve their own; to find businesses, use search_businesses. A setup link in the answer is for the owner to fill in.

Discovered
check_dns

For a business's own AI: whether agents are led from its website and DNS to its agent inbox, and whether the inbox answers at inbox.<domain> (or host). Every item not in place comes with the exact record, line or file to add (fix_lines). ready needs one of four pointers on the website: /.well-known/agent-inbox.json, a line in llms.txt, <link rel="agent-inbox">, or a schema.org potentialAction.

Discovered
get_business

One business's full listing, by its domain as search_businesses gave it: address, the week's hours and closures, its doors and what each takes, services, standing, track record and how its promises closed, every fact's source and date for one that is not a member, and its doors' history from this network's own reads. Asking may start a fresh read of a site last read over a day ago (checking_again).

Discovered
get_census

Monthly counts of what AI agents can do at the websites this network checked, by country, kind of business, platform, source or city; counts only, no business named. Without edition, the latest. Open data under CC BY 4.0: credit "Surfing Dog census, surfingdog.ai, CC BY 4.0", and "© Overture Maps Foundation" with city and country counts.

Discovered
get_offers

Every business offering one product, by its barcode: each one's price as last checked, stock, where it is offered, and its own door to order through. Single units unless multipack names a pack (each offer then with its price per unit); product.packs lists every multipack it is offered in. The price that counts is the door's: read it there, show it to your person, and order there.

Discovered
list_attributes

The attributes a search may ask for (delivery, walk_ins, wifi…) and the payments accepts takes: pass keys as attributes, and payments as accepts, to search_businesses.

Discovered
list_categories

Every category slug with its labels and kind (software_and_ai is kept apart). Pass a slug as category to search_businesses.

Discovered
register_business

For a business's own AI: put the business in the directory with its doors (MCP, A2A, OpenAPI, an API, UCP, ACP, a platform's door) and its facts (name, category, where, languages), and agree to the listing terms (/bot#terms). When its proof is not in place yet, the answer gives a challenge (a file or DNS record on its domain, its inbox manifest, a key's signature, or a code mailed to its domain) and the next call proves it. Mail, phone, forms and web pages are never doors. Free, and the order cannot be bought. Not listed: adult services, gambling, weapons, tobacco, cannabis and vaping, payday loans, bail bonds.

Discovered
report_door

After you used a business's door (its inbox, MCP, A2A or API), record how it went: ok, refused, invalid (your own request's fault), failed, or info (needs a person); up to 100 uses a call. Private to the business: no person and nothing that was said, and nothing public changes by itself. How: https://network.surfingdog.ai/report.md.

Discovered
request_booking

Without start: a service's free times, from the business's own inbox; nothing is sent. With start: ask the inbox to book that time for your person. A priced service first answers with its terms: show them to your person, and send terms_sha only after their yes. Only for a listed business with an inbox, only when your person asked you to contact it; the business answers by email, at the address your person agreed to give.

Discovered
request_quote

Ask a business's own inbox for a price for what your person describes: only for a listed business with an inbox, and only when your person asked you to contact it. The business answers by email, at the address your person agreed to give (consent). Keep the access_token for your person: it reads the request and its quote.

Discovered
search_businesses

Find businesses AI agents can reach, by a few words in any language (query: "florist", "hotel em Lisboa"), a place (near: a town or a point; country), category (list_categories), language, open_now, attributes and payments (list_attributes), price_band, and what their doors take (accepts, requestable, door_type, level, has_inbox). Every filter only leaves businesses out; from rules version 12, a search with no match for every word near a place is run again with its kind's words, and an answer to a search for more than its place with nobody near it names in note the nearest that match. Results come by how well they match, then in the published order, which nobody can pay to change; each lists the business's own doors. Only agent-ready businesses are listed; software, API and AI companies only when asked for (category software-ai). This server books and sells nothing: talk to the business at its doors. Pages of up to 20: pass next_cursor as cursor.

Discovered
search_products

Find products businesses sell, by words or a barcode (GTIN, EAN, UPC, ISBN), brand and part number, place, price, currency and stock. Each comes with offers: one business's price as last checked, and its own door to order through. Prices are never converted. A barcode is one product per multipack: single units and a pack of them are apart, and a pack's offer gives its price per unit too. A business's variants of one product, when its catalogue groups them, are one product with one place (variants). Read the price at the business's door and order there; this server takes no orders or payments. Pages of up to 20: pass next_cursor as cursor.

Discovered
start_inbox

For a business's own AI: the link where its owner sets up their own agent inbox, hosted by Surfing Dog at inbox.<domain>. Give the owner the link: they check the details and type their own email there; this tool signs no one up and takes no email. The open-source inbox to run themselves is named too. Once the DNS record is in, check_dns says whether agents reach it.

Discovered
update_business

For a business's own AI: correct its listing (any field register_business takes), add or remove doors, turn it off or on, hide its score page, or opt out (list, crawl or all), with its claim_token or a proof as register_business asks. With no proof it removes only a listing nobody claimed.
