No Bank for Bots

Some say the next billion Bitcoin users won't be people. They'll be AI agents. But cards and bank accounts are issued to people and companies, after identity checks. An agent has no passport, no address and no credit history. So today it borrows a human's card or API key, and that human's limits.

Bitcoin Needs Only a Key

To receive Bitcoin you need only a private key: a random number a computer makes in under a millisecond. Agents pay per request. A thirty cent card fee is three thousand times a request costing one hundredth of a cent. Lightning moves Bitcoin in about a second, and counts in millisats: one satoshi split a thousand ways. L402 puts the payment inside the web request, using status code four oh two: Payment Required.

Honest Caveats

Someone still funds the agent. A human or company buys the Bitcoin and sets the budget. Routing is not free. Tiny payments need direct channels, zero base fee routes or batching. Competition is real. Stablecoin and card networks are building agent payments too. Cap spending, keep keys on a separate signer, and start small. This video is not investment advice.
