Advertising for the machine web.
AI agents now choose between offers for the people they work for, and they need something they can check. Our own forgery test shows that an attestation label alone can influence a model, so WorldAuth Advertising compiles your ads into sealed records with typed claims, evidence and terms, and gives the reader a verification path instead of asking it to trust the label. A 31-character pointer lets an agent resolve the record and get an answer — or a refusal that says exactly why.

Human interfaces are for humans
Most of the digital world was built to be read by people. An agent sent to use it has to rebuild the meaning from a page that was never addressed to it — the layout, the small print, the asterisk next to the price. A Direct Machine Interface exposes what the human interface was describing: the authoritative state, the capabilities, the constraints and the terms, directly.
The idea is not new. Industrial systems have used direct machine interfaces for decades so that a machine’s state reaches software without an operator reading a dial and retyping it. This is the same principle, applied to advertising rather than to production lines.
Five steps, in this order
- 1. Publish. Your copy compiles into sealed records, authorised by one file on your own domain.
- 2. Point. A pointer goes on every live ad unit’s destination URL. No platform integration, no tag on the page.
- 3. Check. The channel matrix tells you which claims can carry their own conditions, before the media is bought.
- 4. Answer. An agent resolves the pointer and gets typed claims with their substantiation state.
- 5. Transact. An agent asks for a quote and gets one signed with your key, freezing price, unit and terms so your checkout can be held to it.
Your claims, authorised by your domain
A record counts as yours only because your own domain says the key that sealed it is yours. One file at your domain names that key — and, if you want us to host the records themselves, the host permitted to serve them. You can withdraw either by editing that file. Without it, a record will not verify as yours — including one published by us.
Reading is free
Verification takes no API key, no account and no payment. That is a commitment in our terms, with 12 months’ public notice if it ever changes. An agent should never have to pay an advertiser’s vendor to find out whether the advertiser stands behind a claim. The advertiser pays for their own records to be read; the reader never does.
