Lightning Labs has introduced pi402, which it says lets AI agents pay for AI inference through the Bitcoin Lightning Network without an account, API key or credit card, according to a report by Foresight News.
Built on the L402 protocol and incorporating components including Aperture, pi402 supports settlement based on the number of tokens used. An agent can use an embedded wallet to handle payment authentication automatically when accessing a compatible LLM inference service. The report does not say that every inference service supports this payment flow.
