Fewsats is a payments infrastructure platform built for the emerging AI economy. It gives AI agents, assistants, copilots, and autonomous services the ability to request and complete payments without ever being given direct access to financial credentials or payment method details. Instead of handing sensitive financial data to an AI, Fewsats acts as a controlled intermediary that keeps the human user in charge of every meaningful transaction. For clients, the platform provides a developer-friendly SDK that lets AI tools handle HTTP 402 Payment Required responses automatically, so agents can buy API access, data, or other services without forcing the user to switch to a browser or go through a complex setup. Administrators can set budgets, transaction limits, and approval workflows, and every payment request can be routed through a human-in-the-loop review when needed. For service providers, Fewsats unlocks a new revenue channel by making it easy to create paywalled offers and accept micropayments from AI agents with minimal overhead. The platform is designed as a single integration that supports traditional and next-generation payment networks: low-fee ACH and wire bank transfers, universally accepted credit cards, and cryptocurrency stablecoins for global, borderless transactions. Fewsats is aimed primarily at developers building AI-facing products, API services, and agent networks that need a secure, controllable, and frictionless way to move money between software entities and their human owners.
