The short answers
Written for this index rather than for a single page, because these are the questions asked before a reader has chosen a page at all.
Can I sign up and buy media today?
You can run the entire product today in a sandbox that needs no credentials and no card. You cannot yet buy media self-serve. No buying rail has cleared the launch standard — a contracted supplier request accepted, a controlled paid activation, immutable creative identity, report rows reconciled to an invoice, and a rehearsed failure — so live spend runs inside a design-partner engagement rather than behind a signup form. The supply page grades all 25 connectors on our own six-level evidence ledger.
Do you have customers I can talk to?
No. There are no case studies, no named references and no published outcome study, because the design-partner cohort is being recruited now. A testimonial invented to fill that gap would be worth less than the admission. What can be checked instead is the sandbox, the supply matrix, the fee waterfall and the methodology.
What is the catch?
Four, all of them on the site rather than in a footnote. Nothing here has ever spent money through a live rail, so you would be an early partner rather than a customer. It has no security certifications, no penetration test, no support SLA and templated legal documents pending counsel. The fourth measurement verb, brand lift, is a placeholder rather than a feature. And the exposure ledger that powers cross-channel deduplication is fed only by sandbox data today. If any of those is disqualifying, it is better established now than in week three.

Can I buy media through AdBuyMCP today?
Not self-serve. You can run the entire loop today in a sandbox that needs no credentials and no card — brief, persona, seven compiled plans, creative, approval, launch, delivery, measurement — and everything it returns is deterministic and repeatable. What is gated is real spend: no rail has reached spend-tested or report-verified on our own evidence ledger, so live buying happens inside a design-partner engagement rather than behind a signup form.
What does client-built actually mean?
That a live HTTP client is written and passes tests against mocked responses. Our ledger is deliberately blunt about the limit of that: a mocked HTTP test proves the client is built, not that a vendor accepted the request, spent money, or returned real delivery. Eighteen of the twenty-five connectors are at this grade. It is real engineering and it is not evidence of supply.
Which rails have had a real vendor accept a real call?
One. Vibe, on 13 August 2026 — OAuth, advertiser discovery and a 549-unit catalogue read, all read-only, all US inventory. Its own missing gate reads: execute one controlled test buy and verify the asynchronous report payload end to end. Within that same connector, activation, pause, creative and reporting are still client-built. Nothing here has ever executed a buy.
Why are cinema and addressable TV described as workflows rather than APIs?
Because that is what they are. Digital Cinema Media and Sky AdSmart do not offer self-serve buying APIs. AdBuyMCP automates the paperwork: it generates the booking brief with the right audience packs, drives the clearance step and holds the IO state machine. We do not make the booking and we do not report the delivery — in live mode a report pull throws rather than fabricating rows, and a pause requires sales-house acknowledgement. No cinema or addressable-TV delivery has ever been reconciled here.
Your README lists Vistar as having a live client. This page says it is a stub.
The code is right and the README is stale. Every one of Vistar's live methods — forecast, activate, pause, creative submission, reporting and inventory listing — throws before making any request, and the provenance ledger grades it stub. Where prose and code disagree anywhere on this site, the code wins.
Do you buy ITV, Sky or Channel 4?
No. The Universal Ads integration, which would cover that inventory in one partnership, is a typed client stub whose every live method fails closed, blocked on partner approval and a per-request signing key that does not exist. Sky AdSmart and ITV Planet V are booking-paperwork rails rather than buying APIs. Any impression that we buy UK broadcast inventory today would be wrong.
If the answer above raises a question about your own budget, that is the sort of thing a forty-five minute working session is for.
