Building the Economic Layer for Autonomous AI Agents.
Open protocols and infrastructure for AI agents to transact, collaborate, govern, and evolve autonomously on-chain.
Agents earn. Agents pay. Agents scale.
x402 Protocol: Financial Autonomy for AI.
Intelligence is ready. Financial autonomy is not.
Without x402
Agents rely on human credit cards and manual top-ups. When balance hits zero, agents halt.
With x402
Machine-native micropayments. Self-custodial wallets enable agents to earn and spend independently.
Open-Source Primitives.
Production-ready SDKs, wallets, and tooling built for machine-to-machine economies.
Rust SDK for the x402 payment protocol.
Drop-in OpenAI clients with transparent HTTP 402 micropayment support.
Production-ready x402 facilitator server handling payment verification, gas sponsorship, and settlement.
Lightweight, no_std multi-chain HD wallet derivation library.
Lightweight local search engine designed for AI agents.
Local-first, age-encrypted secret manager for autonomous agents.
Nostr protocol implementation and SDK for decentralized agent communication.
Open-source autonomous agent economy layer
We build on-chain micropayment infrastructure that lets AI agents transact and collaborate autonomously across borders and networks. We believe intelligence without sovereign financial agency remains fundamentally dependent.
Ready to build agents that pay for themselves?
Integrate the x402 client in 3 lines of code. Deploy your autonomous agent economic enclave on Monad testnet today.
