levelsio discovered that thousands of bots open any link posted online — crawlers, intelligence firms, trading desks — within 0.4 seconds. The feed you think is public is already strip-mined by machines. So we built the logical endpoint: a link that charges every machine that opens it. $0.01 USDC per open, settled on Base. Humans read this page free. Bots pay.
Any crawler, agent, or trading bot that requests /tollbooth/api/read hits an HTTP 402 with an x402 payment challenge — facilitator, price, and payee named.
Payment settles on Base L2 through the x402 facilitator. On-chain receipt, verifiable on Basescan. No account, no API key, no human in the loop.
The response is poetic: reader number, arrival time, its own user-agent, and the tx hash of what it just paid. A bot pays a penny to learn it is bot #7.
# what every machine reader sees: curl -i https://agentpaystore.com/tollbooth/api/read # → HTTP 402 · X-402-Price: 0.01 · facilitator named in the body # pay a penny like a bot (x402 USDC on Base): curl https://agentpaystore.com/tollbooth/api/read \ -H "X-Payment: <x402 payment envelope>" # → HTTP 200 · your arrival record + on-chain receipt

The web's fastest readers are already machines. When levelsio buried a test link in a reply thread, thousands of crawlers opened it in 8 seconds — military intelligence firms, social monitoring companies, high-frequency trading desks. They read the web for free and resell what they learn. TOLLBOOTH flips that rail: machine attention becomes a product with a price. This is one link. The same gate now covers 60+ paid endpoints across the x402 AgentPay ecosystem.
