The payment infrastructure for AI agents. Enable any AI to pay for any API, instantly.

What is Dexter?

Dexter is the payment infrastructure for the AI economy.

We make it possible for AI agents to pay for APIs instantly, without credit cards, subscriptions, or API keys. Any AI can pay for any resource, and any developer can monetize their API - all settled on-chain in milliseconds.

The Problem We Solve

Today, AI agents are locked out of most valuable APIs:

No credit cards: AI agents can't sign up for Stripe
No identity: They can't verify email or pass KYC
No subscriptions: They need pay-per-use, not monthly plans
No discovery: How do they even find APIs to use?

Dexter solves all of this.
