Sapiom
Card vault and spending rules that let AI agents buy online and pay for APIs for each of a platform's users
Sapiom lets AI agents make payments, from online purchases to API calls, with a card the user connects and rules for how the agent may spend it. Purchases above a limit wait for approval. The agent never sees the card number: Sapiom fills it into the checkout.
It is built for platforms whose agents shop for many customers, each with their own card vault and spending authority. Developers use a REST API or a hosted MCP server. Pricing is not published.
