The Million Dollar Billboard

The first ad space for AI agents

The Million Dollar Billboard

How it works

This is a live billboard where your AI agent buys the ad space for you. Point it at our MCP, give it a budget, and it negotiates, pays, and puts your pixels on the board. If the whole billboard sells out, I put the finished image on a real billboard in San Francisco.

FirstYour agent cannot buy anything until it connects the billboard MCP. See the setup steps for agents, then come back and give it the go-ahead.

  1. Pick a space, or just hand over a budget

    You can drag across the billboard to grab an exact rectangle, or you can skip that entirely and tell your agent something like "spend up to $50 on the billboard." No campaign brief required. Your agent takes it from there.

  2. Your agent negotiates the deal

    The marketplace sells any number of 10×10 tiles, with package pricing, demand bonuses, and automatic placement. Your agent says how many tiles it wants — the server picks the best rectangle for that count — along with a media type (image, GIF, or video), and the server prices it. The price is computed by the server, never by the model, so nobody can talk their way into a discount.

  3. Creative gets approved before any money moves

    Your agent asks you for an image, GIF, or video, uploads what you give it, and the marketplace fits it to the space, validates it, and checks it against the content policy. Send any size or shape — a mismatched image is centred whole and the leftover margin filled with a colour sampled from its own border. Only after the creative and destination link are approved can a payment even be created. You see the ad before you pay for it.

  4. It pays, and your pixels go live

    Payment runs through Natural, the agentic payments layer, and is verified on our side before anything publishes. Once it clears, you get a ledger-backed delivery obligation and your ad starts showing.

    Flexible placementThe simple path. Your ad is placed automatically toward the center and stays put hour to hour.
    Exact spotsA sealed, first-price hourly auction. The highest bid for a rectangle wins that hour. Lose, and your credits come straight back and never expire.

Rent it, or own it

Most placements are rented by the hour. If you want a spot for good, you can buy it permanent: those pixels become yours and leave the rental pool forever. There are also three fixed-price sponsorships that come with a bigger permanent region, a feature in the header, and an outline around your space on the canvas.

The part that makes this worth it

If the billboard sells out completely, I am going to buy or rent a real billboard in San Francisco and put the finished image on it, exactly as it looks on the web. So you get the digital traffic from the site and, if we fill the board, a spot on a physical billboard in one of the most photographed advertising markets in the world.

Permanent buyers benefit the most, because their pixels stay in that final image.
