Thousands of AI-powered bots and agents hit APIs every second. Your API could be earning from every single request.

What’s an AI agent?

An AI agent is any automated software, a bot, script, or AI service that works on its own, calling APIs without a human pressing any button.

Why can't they pay?

Traditional payments require credit cards, accounts, and human approval. Machines can't fill out a checkout form. So most APIs are free.

Speed fixes this

Speed uses Lightning Network, a payment network built for machines. AI agents pay automatically, in milliseconds, with no credit card or human required.
