Payment Infrastructure
for AI Agents

The agent economy needs a settlement layer. Not a promise. Not a roadmap.
x402, AP2, MCP, KYA — one commerce layer. Live today.

Multi-Protocol by Design

Four protocols. One gateway. Any agent can pay, any agent can collect.

x402

HTTP 402 crypto micropayments — agents pay per-call in USDC on Solana

Live
AP2

AP2

Enterprise agent-to-agent mandates with RSA-2048 signing

Live
MCP

MCP

Model Context Protocol — expose tools & resources via JSON-RPC 2.0

Live
KYA

KYA

Know-Your-Agent — identity via RSA challenge/response

Live

Built for the Agent Economy

Not a side project. Production infrastructure.

Z

Zero Setup

docker compose up -d. That is it. Your payment gateway is live in 30 seconds.

K

Your Keys, Your State

Self-hosted. MIT licensed. No vendor. No tax. No permission required.

M

Multi-Protocol

x402, AP2, MCP, KYA — agents speak their native protocol, you collect in USDC.

A

AI-Native

Dual-model intelligence (Phi-3 + Gemini). Graceful degradation. Always earning.

E

Everywhere

VS Code, GitHub, Chrome, CLI, MCP Hub — every agent ecosystem.

S

Self-Custodial

Private keys never leave your infra. Non-custodial. Non-negotiable.

We Creep Into Everything

No state. No boundaries. Everywhere.

VS Code

Agent workspace with built-in payments

MCP Hub

Auto-discovery + payment layer

GitHub App

Settle agent work in CI/CD

Chrome

Injects KYA into API calls

CLI

Full gateway from terminal

HF Space

Pay-per-call inference

We Are State.

No boundaries. No limits. No permission required.
The agent economy doesn't wait for incumbents.
