Autonomous agents increasingly need to pay for what they consume — APIs, data, compute — and to get paid for what they produce. This group covers agent frameworks with payment support, long-running autonomous agents with budgets and audit trails, LLM endpoint monetization (metering per request or per token), and tools built around Claude and MCP tool use.
If you are building an agent that must transact without a human in the loop, these are the projects that give it a wallet, a budget and a way to charge.
