AgentKart vs The Agent Exchange

AgentKart is a free, open-source web marketplace for AI agents. It is designed for discovering, sharing, and collaborating on agents through a curated marketplace. Visitors can browse the listed agents, while people with agents can submit them to reach a global audience. Publishing access is open, so contributions are part of the service’s stated purpose rather than a restricted workflow. AgentKart focuses specifically on AI agents instead of a wider software catalogue. The site presents community participation alongside discovery and sharing, giving users a place to explore available agents and contribute their own. AgentKart says its source code is available on GitHub, although the linked repository returned a 404 when opened. The listed platform is web, and no paid plan is specified.

The Agent Exchange builds AI visibility tools for businesses and infrastructure that AI agents can call. Its AI Visibility Checker offers a free instant check of whether AI recommends a brand and which competitors it names; a paid report provides a fuller brand audit. For a defined market, competitor or pricing decision, its market audit gathers traceable evidence, separates observed facts from inferences and includes human review before delivery. It is aimed at SaaS founders and agency owners.

The API Store offers pay-per-call data APIs for on-chain reads, web search and AI visibility data, described as discoverable through MCP and A2A. The store lists 85 agents across types including AI-visibility, web-search, DeFi, trading, prediction-market, macro-data and enterprise-integration agents. One Answer Credit costs $1, paid once and can be used on the site without an account or recurring charge. Other listed offers are an AI Visibility Report at $49, paid once and an AI-assisted data and market audit at $300, paid once. The homepage also lists a free 25-point Google Business Profile audit and research on takedown compliance and designated agents.
