Kite launches Agent Passport for autonomous AI agent payments

Kite launched the mainnet for Kite Chain and Kite Agent Passport on April 30, 2026. Agent Passport is identity and payment infrastructure built for autonomous AI agents, designed to let agents pay for services on behalf of users within pre-approved limits.

The sources are Kite’s GlobeNewswire release and the company’s own Agent Passport documentation. The docs describe Passport as “payment rails for AI agents”: the user grants an agent a scoped spending session with a per-transaction limit, a total budget, a time limit and an allowed asset list. Payments are approved with a passkey before funds can move.

This addresses one of the practical bottlenecks for agents. An agent that needs to buy data, use paid APIs, purchase a service or complete a commerce flow needs more than tool access. It needs identity, delegation, budget, traceability and settlement. Without that, companies are stuck with manual approval at every step or risky shared payment credentials.

Kite says Agent Passport supports x402 payments and positions itself against several agent payment standards, including Google’s AP2, Stripe’s Machine Payment Protocol and Anthropic MCP. The company also cites pilot integrations with PayPal and Shopify. That makes this more interesting than a pure crypto launch, although the stablecoin and chain components still require sober assessment.

For leaders, the point is simple: if agents are going to act in the world, the business needs financial authority models for non-human actors. This applies to procurement, API consumption, support refunds, travel booking and eventually B2B transactions.

Assessment: agent payments are still early, fragmented and full of standards conflict. But identity, budget and audit trails for agent spending will become real enterprise requirements. Kite is one of the companies trying to make that concrete now.
