The AdPrompt Marketing Platform combines multiple purpose-built AI agents to deliver a comprehensive toolkit that helps small businesses drive brand awareness and sales in their local markets. In minutes, users can generate on-brand creative content, optimize across key marketing channels, and launch campaigns tailored to their location, audience, and voice.
AdPrompt’s intelligence layer is powered by a suite of trained, specialized AI engines, each designed to automate and optimize a specific marketing or advertising task that often overwhelms small business owners. Rather than working in isolation, these engines are orchestrated to operate together as a cohesive system.
This enables seamless handoffs and collaboration among capabilities, such as analyzing a brand’s identity, generating on-brand creative assets, planning and optimizing ad campaigns across multiple channels, dynamically testing and iterating, and converting performance data into actionable insights. As the platform evolves, new engines are introduced, expanding the breadth and depth of automation available to users. Together, these agents handle the heavy lifting so business owners can focus on serving their customers.

x402 AdPrompt Agent API Capabilities
In simple terms, x402 is a programmable micropayment protocol that enables APIs to be accessed and paid for on a per-call basis without the need for subscriptions or billing accounts. x402scan is a discovery layer and marketplace where users can browse resources that use the X402 payment protocol, and pay for calls via web UI or automated tools.
AdPrompt has deployed three purpose-scoped API resources on x402, powered by its specialized AI engines. These resources let users analyze brand properties, generate on-brand creative assets, and receive strategic recommendations, all with a single API call and micro-payment.

x402 and Shifts to the Agentic Advertising and Attention Economy Landscape
Part of AdPrompt’s mission is to automate the discovery and connection between local small businesses and relevant targeted local advertising opportunities. As the advertising ecosystem evolves beyond traditional programmatic workflows, the industry is moving toward an agentic model, where interoperable agents can identify opportunities, generate creative, execute campaigns, and continuously optimize performance.
“As the advertising industry rapidly becomes ‘agentic’, the tools around it must become agentic too. Unlike legacy systems, agentic systems work continuously with a seamless user experience: discovering opportunities, generating creatives, testing variations, optimizing spend, and reacting in near real time,” said Brook. “x402 brings a missing piece to the internet: a way to attach payments directly to an API call. Instead of requiring subscriptions, contracts, billing accounts, and complicated onboarding flows, x402 turns access into something much more natural: pay only for what you use, when you use it.”
With x402, a small business can invoke a capability, pay a micro-fee, and receive an output instantly. At the same time, enterprises and autonomous systems can run the same workflow at scale, executing thousands of paid calls per day with minimal friction.
