Superstables is building payment infrastructure for the emerging agent-to-agent economy. The core idea is simple: AI agents should be able to discover the data, tools and services they need, understand the price and payment terms, and then complete those purchases through a wallet with permissions defined by the owner. The public Superstables Index already makes payable services discoverable through REST, MCP and natural-language access. V1 is being built to extend that discovery layer into payment execution, allowing agents to interact with supported payment protocols and rails through a common interface while keeping the user in control through manual approvals, spending budgets or dedicated agent wallets.
