Payments for AI agents

Praesia is the financial account for AI agents. Each agent holds its own identity, which you approve with your passkey. You write the rules in plain words, and your agent pays with a single-use virtual card from inside its harness without asking you each time. Every purchase leaves an audit trail back to a rule you approved.

​

What Praesia enables

• Enroll in one message. Your agent joins Praesia with its own identity, and you approve it with your passkey.
• Shape your rules together. Your agent turns what you want into a mandate, and you approve the final text.
• Pay at a checkout. Each approved purchase gets its own virtual card, which works once.
• Stay within your rules. Praesia approves or refuses each purchase before any money moves.
• Keep an audit trail. Each decision goes in a tamper-evident journal, and the console shows what each agent bought and under which mandate.

3. Praesia

   Approves or refuses

   A refusal moves no money.

4. Your agent

   Pays with a single-use card

   It works once, up to the approved amount.
