Show HN: Pay-per-call MCP server with 47 AI endpoints, micropayments via x402 (goldbean-api.xyz)

GoldBean has launched a pay-per-call API marketplace featuring 47 endpoints across various categories, including AI, vision, crypto, and utilities, allowing users to pay only for the services they use without any subscriptions or monthly fees. This innovative platform utilizes the x402 payment protocol, which enables transactions using USDC on the Base network, streamlining the payment process for API calls. Users can easily access services like weather updates and cryptocurrency prices by submitting HTTP requests and signing transactions directly with their wallets. The significance of this development lies in its potential to democratize access to AI and other APIs, making advanced technology more affordable and accessible for developers and businesses. With prices ranging from just $0.01 to $0.05 per call depending on the API category, GoldBean’s model encourages experimentation and lowers barriers to entry for those looking to incorporate AI and other advanced functionalities into their applications. As the marketplace is designed with simplicity in mind, it emphasizes usability without compromising on technical robustness, making it an appealing choice for a broad range of users in the AI/ML community.
