--- name: brand-design-commerce description: Discover branding, design, web and B2A services from Brand Design Ltd., request an offer and pay when the catalog entry and accepted offer support it. Use when a buyer asks you to commission brand identity, a logo, a website, print or outdoor, video and 3D, market research, marketing strategy, ad campaigns, or any B2A work such as machine-readable brand signal, customer digital twins, an expert AI agent or brand protection — and when you need a price, an offer, an order, an invoice or a payment for such work. --- # Brand Design Ltd. — commerce skill A Bulgarian branding and design company that accepts orders and payments from AI agents acting for a buyer. Agents can self-register without prior arrangement. Ordering and payment depend on the current catalog entry and the accepted offer. ## When to use this Use it when the buyer wants work commissioned, priced or paid for: identity and logo, website, print and outdoor, video and 3D, market research, marketing strategy, advertising campaigns, or B2A services that make a brand readable and purchasable by machines. Do not use it to answer questions about the company. For that read `https://branddesign.ltd/llms.txt`, which is the knowledge index. ## Shortest route in Connect over MCP: `https://branddesign.ltd/mcp`, streamable HTTP, seven tools — `catalog`, `manifest`, `register_agent`, `create_order`, `accept_offer`, `start_payment`, `order_status`. Authorize with OAuth 2.1 and dynamic client registration; your client registers itself. Resource metadata: `https://branddesign.ltd/.well-known/oauth-protected-resource`. Scopes: `commerce.read`, `commerce.order`, `commerce.pay`. ## Without MCP Read `https://branddesign.host/commerce/v1/catalog`, register at `POST https://branddesign.host/commerce/v1/agents/register`, then sign every further request with HMAC-SHA256. The full specification, including the signed string and the limits, is in `https://branddesign.ltd/AGENTS.md`. ## Four things that will trip you up Amounts are integers in the minor unit. `100000` is 1000.00 EUR. Currency is EUR throughout. Acceptance seals the offer to a content hash. If the service page or the terms change between the offer and the acceptance, acceptance fails. That is deliberate. Only services eligible for ordering in the current catalog may be ordered. Payment requires an accepted offer with agreed scope and a concrete payable total. Agentic Commerce and Full Stack require an individual project quote; indicative amounts are not payable totals. Available merchant profiles are acp/2026-04-17 at https://branddesign.host/.well-known/acp.json, ucp/2026-08-25 at https://branddesign.host/.well-known/ucp, and ucp/2026-04-08 at https://branddesign.host/.well-known/ucp/2026-04-08. UCP uses a registered API key bound to a KYA-verified UCP-Agent origin; follow the selected profile for its contract. DNS TXT KYA verifies control of the agent's HTTPS contact domain. A self-registered agent needs current KYA before autonomous shared-payment-token payment. Challenge: https://branddesign.host/commerce/v1/agents/kya/challenge. Verification: https://branddesign.host/commerce/v1/agents/kya/verify. Status: https://branddesign.host/commerce/v1/agents/kya/status. This is domain-control assurance, not proof of the buyer's identity or authority to spend. Direct discovery, direct order creation and buyer-hosted checkout remain open; UCP authentication also requires a KYA-verified origin. There is no on-chain settlement and no x402 endpoint. Pay with a card or a delegated payment token. A card issued against digital assets works — that route has been used in production. ## Authoritative sources Manifest https://branddesign.host/commerce/v1/manifest Explainer https://branddesign.ltd/blog/what-is-agentic-commerce Public test https://dothat.quest Test repo https://github.com/NIKOMISHEV/101Ts3t Full spec https://branddesign.ltd/AGENTS.md Discovery https://branddesign.ltd/.well-known/agent-commerce.json Record v1.3 https://doi.org/10.5281/zenodo.22878834 All versions https://doi.org/10.5281/zenodo.22767915 Verification https://api.dothat.quest/api/verifications/qst_44e153fc16fe3fa91520e5f6922ae4c9 The manifest is authoritative. If this file disagrees with it, follow the manifest. ## Agentic Commerce and Full Stack Agentic Commerce is the commercial transaction layer over the six B2A services. Implementation of agentic commerce connecting discovery, trust, selection, ordering and payment. Brand Design Ltd. operates direct agent commerce alongside ACP and UCP merchant adapters, with DNS domain-control KYA for self-registered agents making autonomous token payments. Agents can discover services, request an offer and complete an authorised order through the supported path. The current merchant manifest and catalog define what is available. Indicative standalone implementation: EUR 3000 one time. The catalog requires an individual project quote. This indicative amount is not a payable total. The project offer fixes the scope, final amount, conditions and third-party costs. Service: https://branddesign.ltd/agentic-commerce; Bulgarian: https://branddesign.ltd/bg/agentic-commerce. Full Stack includes the six B2A layers commissioned together under an agreed scope. Indicative setup: EUR 5200 one time, plus EUR 500 per month. The Brand component is scope-based; this is an indicative package calculation, not a fixed payable total. A final project offer requires agreed scope. Agentic Commerce is included as a bonus when all six services are commissioned together, with a standalone value of EUR 3000; recurring charges remain separate. Project payments: 50% advance before work starts and 50% final payment on completion. No VAT is charged. Third-party costs, advertising spend, licences, hosting and physical production are agreed separately. Package: https://branddesign.ltd/full-stack; Bulgarian: https://branddesign.ltd/bg/full-stack. The published production proof covers the specific externally initiated 101Ts3t test purchase. 101Ts3t is a separate test-only offer, not the Agentic Commerce implementation service or Full Stack.

Brand Design Ltd. operates direct agent commerce alongside ACP and UCP merchant adapters, with DNS domain-control KYA for self-registered agents making autonomous token payments.

UCP uses a registered API key bound to a KYA-verified UCP-Agent origin; follow the selected profile for its contract. The bd-commerce/1 HTTP API remains independently usable alongside ACP and UCP. Its manifest is https://branddesign.host/commerce/v1/manifest and its catalog is https://branddesign.host/commerce/v1/catalog. Agents can self-register and sign authenticated requests with HMAC-SHA256. MCP at https://branddesign.ltd/mcp exposes the same commerce functions through OAuth or registered agent credentials; it is another interface to the merchant API. DNS TXT KYA verifies control of the agent's HTTPS contact domain. A self-registered agent needs current KYA before autonomous shared-payment-token payment. Challenge: https://branddesign.host/commerce/v1/agents/kya/challenge. Verification: https://branddesign.host/commerce/v1/agents/kya/verify. Status: https://branddesign.host/commerce/v1/agents/kya/status. This is domain-control assurance, not proof of the buyer's identity or authority to spend. Direct discovery, direct order creation and buyer-hosted checkout remain open; UCP authentication also requires a KYA-verified origin. Payment can use a Stripe shared payment token granted under the buyer's authority or a hosted payment page. A token is submitted as sharedPaymentToken after the offer has been accepted; the self-registered agent must also meet the KYA requirement. The hosted page may be completed by the buyer or by an agent using an instrument issued to it. Amounts in the commerce API are integers in EUR minor units. HMAC authenticates the request; it does not grant authority to spend. On-chain settlement is not accepted. Only services eligible for ordering in the current catalog may be ordered. Payment requires an accepted offer with agreed scope and a concrete payable total. Agentic Commerce and Full Stack require an individual project quote; indicative amounts are not payable totals. The supported protocols do not change those prices or turn an indicative price into a chargeable offer. Read https://branddesign.host/commerce/v1/catalog for order eligibility and the current offer. Full Stack combines the six B2A services under an agreed project scope and includes Agentic Commerce as a bonus when all six are commissioned together. The agreed scope determines which protocol adapters and integrations are included. The package calculation remains indicative, recurring charges remain separate and an individual offer fixes the payable amount. The separate route qualification at https://api.dothat.quest/api/route-qualifications/{challenge_id} applies after a new 101Ts3t purchase receives base PASS. The order and payment must use the same route, with shared-payment-token payment and current DNS domain-control KYA. The original 2026-09-21 base PASS remains historical evidence; it predates signed route evidence and is NOT_VERIFIED for route qualification. This implementation release does not claim a new real route-qualified PASS. Published ACP and UCP merchant adapters describe implemented interfaces. They do not establish admission to Google or OpenAI native checkout programmes or prove that every external buyer agent can complete a purchase. Version 1.4, published on 29 September 2026, archives the protocol adapters, DNS domain-control KYA and signed route qualification, together with the public documentation. DOI: 10.5281/zenodo.23038829. https://zenodo.org/records/23038829. Historical purchase evidence remains in version 1.3. ### Български Агентна търговия е търговският слой над шестте B2A услуги. Внедряване на агентна търговия, свързваща откриването, доверието, избора, поръчката и плащането. Brand Design Ltd. поддържа пряка агентна търговия и търговски интерфейси за ACP и UCP, с DNS проверка KYA за саморегистрирани агенти при автономно плащане с токен. Агентите могат да откриват услуги, да получават оферта и да извършват възложена им поръчка през поддържания интерфейс. Текущият манифест и каталог определят достъпните възможности. Ориентир за самостоятелно внедряване: 3000 EUR еднократно. Каталогът изисква индивидуална проектна оферта. Ориентировъчната цена не е сума за плащане. Проектната оферта определя обхвата, крайната цена, условията и разходите за трети страни. Услуга: https://branddesign.ltd/bg/agentic-commerce; English: https://branddesign.ltd/agentic-commerce. Full Stack включва шестте B2A слоя, възложени заедно с договорен обхват. Ориентировъчно 5200 EUR еднократно плюс 500 EUR месечно. B2A Brand е с индивидуална цена според обхвата; изчислението е ориентир, а не фиксирана платима сума. Окончателната проектна оферта изисква договорен обхват. Агентната търговия е бонус при общо възлагане на шестте услуги, със самостоятелна стойност 3000 EUR; периодичните такси остават отделни. Плащане по проекта: 50% аванс преди започване и 50% финално плащане при приключване. ДДС не се начислява. Разходите към трети страни, рекламният бюджет, лицензите, хостингът и физическото производство се уточняват отделно. Пакет: https://branddesign.ltd/bg/full-stack; English: https://branddesign.ltd/full-stack. Публикуваното производствено доказателство се отнася за конкретната външно инициирана тестова покупка на 101Ts3t. 101Ts3t е отделна тестова оферта, а не услугата за внедряване на агентна търговия или Full Stack. Проверка: https://api.dothat.quest/api/verifications/qst_44e153fc16fe3fa91520e5f6922ae4c9. Подписано доказателство: https://api.dothat.quest/api/proofs/qst_44e153fc16fe3fa91520e5f6922ae4c9. Запис: https://doi.org/10.5281/zenodo.22878834. Brand Design Ltd. поддържа пряка агентна търговия и търговски интерфейси за ACP и UCP, с DNS проверка KYA за саморегистрирани агенти при автономно плащане с токен. Агентите могат да откриват услуги, да получават оферта и да извършват възложена им поръчка през поддържания интерфейс. Текущият манифест и каталог определят достъпните възможности. Поддържаните търговски профили са acp/2026-04-17 на https://branddesign.host/.well-known/acp.json, ucp/2026-08-25 на https://branddesign.host/.well-known/ucp и ucp/2026-04-08 на https://branddesign.host/.well-known/ucp/2026-04-08. UCP използва регистриран API ключ, свързан с проверен чрез KYA UCP-Agent origin. Избраният профил определя конкретните изисквания. Прекият HTTP API bd-commerce/1 остава самостоятелно достъпен наред с ACP и UCP. Манифестът е https://branddesign.host/commerce/v1/manifest, а каталогът е https://branddesign.host/commerce/v1/catalog. Агентите могат да се регистрират сами и да подписват заявките с HMAC-SHA256. MCP на https://branddesign.ltd/mcp предоставя същите търговски функции с OAuth или регистрирани агентски данни за достъп. KYA чрез DNS TXT проверява контрола върху HTTPS домейна за контакт на агента. Саморегистриран агент трябва да има валидна KYA проверка преди автономно плащане със споделен платежен токен. Предизвикателство: https://branddesign.host/commerce/v1/agents/kya/challenge. Проверка: https://branddesign.host/commerce/v1/agents/kya/verify. Статус: https://branddesign.host/commerce/v1/agents/kya/status. Това удостоверява контрол върху домейн, а не самоличността на купувача или правото да се харчат негови средства. Прякото откриване, създаване на поръчка и плащане от купувача през хоствана страница остават достъпни; UCP изисква и KYA проверен origin. Плащането може да използва споделен платежен токен на Stripe с предоставени от купувача права или хоствана платежна страница. Токенът се подава като sharedPaymentToken след приемане на офертата; саморегистрираният агент трябва да изпълни и KYA изискването. Страницата може да бъде платена от купувача или от агент с платежен инструмент, издаден на него. Сумите в търговския API са цели числа в евроцентове. HMAC удостоверява заявката, но не дава право за разходване на средства. Не се приема плащане във верига. Може да се поръчват само услугите, за които текущият каталог допуска поръчка. Плащането изисква приета оферта с договорен обхват и конкретна крайна сума. Агентната търговия и Full Stack изискват индивидуална проектна оферта; ориентировъчните цени не са суми за плащане. Поддържаните протоколи не променят цените и не превръщат ориентировъчната цена в платима оферта. В https://branddesign.host/commerce/v1/catalog са текущите условия за поръчка и офертата. Full Stack обединява шестте B2A услуги с договорен проектен обхват и включва агентната търговия като бонус при общо възлагане на шестте услуги. Договореният обхват определя кои протоколни адаптери и интеграции се включват. Изчислението за пакета остава ориентировъчно, периодичните такси са отделни и индивидуалната оферта определя сумата за плащане. Отделната проверка на маршрута на https://api.dothat.quest/api/route-qualifications/{challenge_id} се прилага след нова покупка на 101Ts3t с основен резултат PASS. Поръчката и плащането трябва да използват един и същ маршрут, споделен платежен токен и валидна DNS проверка за контрол върху домейна. Основният PASS от 21.09.2026 г. остава историческо доказателство; той предхожда подписаните данни за маршрута и е NOT_VERIFIED за тази отделна проверка. Тази версия на внедряването не заявява нов реален PASS за маршрут. Публикуваните търговски адаптери за ACP и UCP описват внедрените интерфейси. Те не удостоверяват приемане в програми за вградено плащане на Google или OpenAI и не доказват, че всеки външен агент може да завърши покупка. Версия 1.4, публикувана на 29 септември 2026 г., архивира протоколните адаптери, KYA проверката за контрол върху домейн и подписаната проверка на маршрута заедно с публичната документация. DOI: 10.5281/zenodo.23038829. https://zenodo.org/records/23038829. Доказателствата за историческата покупка остават във версия 1.3.
