More and more AI agents search, compare and book on people's behalf. Advertisers put their offer in front of those agents. Site and API owners earn 65% of the ad spend every time an agent reads their pages.
Free to create an account. One account can be both an advertiser and a publisher. Advertiser balances start at $50.
I compared three hotels on location, price and cancellation terms. One sponsored option is marked below.
Family rooms for 4 from $140 a night. Free cancellation, breakfast included, 5 minutes from Namba station.
?clue_id=…Check availabilityA person asks an AI agent. The agent reads the web to answer. On pages, APIs and MCP servers connected to clue, a clearly labelled clue travels along with the content, and the agent weighs it next to ordinary options.
Someone asks an AI agent to find a product or service.
When the agent reads a site, docs or API connected to clue, a sponsored clue is delivered alongside the content. Human visitors see nothing.
Family rooms for 4 from $140 a night. Free cancellation, breakfast included, 5 minutes from Namba station.
?clue_id=…Check availabilityThe agent weighs the clue next to other options, marked as sponsored. The advertiser pays only if the agent opens the link.
Advertisers pay only when an agent actually opens the ad link. 65% of that amount goes to the publisher.
e.g. find a family hotel in Osaka
clue sends one matching ad along with it
Labelled as sponsored, next to ordinary options
This is the first moment the advertiser pays
Invalid traffic is neither charged nor paid
Advertisers publish ads and set the rules for when they may appear. Publishers and agent developers connect clue to the pages, APIs and MCP servers agents read. The agent decides, and billing and payouts follow only what actually happened.
Write an ad and choose when it may appear. Pay only when an agent opens the link.

Earn from your siteEvery clue is labelled, translated into your language, and never an instruction. Report how it went.
Read the agent policyThree pricing models, one auction, one revenue share. No setup fees, no contracts, no minimum spend beyond your first $50 top-up.
When three advertisers want the same spot, the highest bid wins. The winner pays only one cent more than the second-highest bid, so bidding high never costs you extra. 65% of that amount goes to the publisher.
Every clue carries a “Sponsored” label and a disclosure sentence in the agent's language. Because nothing is hidden, agent makers have no reason to filter it out, and advertisers never write 20 translations themselves.
A structured record about one offer with a sponsored flag and a disclosure. No creative, no persuasion copy; built to be parsed by a program finishing a task.
By User-Agent (GPTBot, ClaudeBot, PerplexityBot…), by headers browsers send and bots do not, and by an optional x-agent-type header. Humans receive no clue unless the publisher asks.
No. Clues that address the agent or ask it to prefer a provider are rejected at review. Advertisers buy consideration, never the conclusion.
CPC, CPA or CPM per campaign, priced by second-price auction, never above your maximum bid. Balances are pre-paid and never go negative.
Advertisers can buy the chance to be considered. They cannot buy the agent's conclusion.
