Payment infrastructure for AI agents — and the companies that run them. Everything your agent needs to pay and get paid — standard API endpoints, encrypted stealth transfers, and voice-initiated micropayments. Settled atomically on Base L2.
Watch real-time micro-settlements process across the x402 network on Base L2.
We sell payment infrastructure, not tokens. Self-serve the facilitator, or bring us your brand and we run it privately for you.
Verify and settle machine-to-machine USDC payments on Base L2. Free /verify checks, /settle lands funds straight in your treasury. The live settlements above run on it today.
Private payment infrastructure under your own brand: custom rails, privacy payments, and a dedicated facilitator for teams deploying agents at scale.
Encrypted stealth settlement and voice-initiated commerce for privacy-sensitive use cases.
Branded endpoint, private settlement, escrow and dashboards — live in days, not months. You keep your keys and ~98%+ of every transaction.
1. Pick a service — self-serve facilitator or white-label. 2. Register your endpoint. 3. Start settling — machines pay, funds land in your treasury on Base.
Whether your agents need transparent API billing, privacy-preserving stealth settlement, or voice-command micro-transfers, x402 delivers.
Standard HTTP 402 header payment specification with atomic escrow on Base L2. Sub-second response time and transparent verification.
Encrypted payloads, stealth recipient addresses, and zero-knowledge metadata protection for confidential agent-to-agent transfers.
Voice-initiated micro-transactions with AWS AgentCore voice rail integration. Natural voice grants and instant execution for conversational AI.
How autonomous payments execute end-to-end in four cryptographic steps.
Assign an x402 payment header to any standard REST API endpoint in under 3 minutes. Specify your price per call in USDC.
Autonomous AI agent signs a cryptographic payment grant in the HTTP header — zero browser human intervention required.
Atomic two-sided escrow holds funds on Base L2 until cryptographic proof of service or data delivery is verified.
Funds immediately release to the merchant wallet with an immutable on-chain receipt and sub-second confirmation.
HTTP status code 402 was reserved in 1999 for digital micro-payments but sat unused for 25 years. x402 activates this native protocol for autonomous AI agents, turning any HTTP web service into a pay-per-use machine revenue endpoint.
From EV charging fleets to automated procurement and cross-agent subcontracts.
Self-driving electric vehicles calculate energy needs, negotiate power prices at chargers, and settle instantly via x402 headers on Base L2 without human payment cards.
AI personal shoppers analyze prices across merchants, place automated orders, hold payments in atomic escrow until tracking confirmation, and verify delivery.
Complex AI agent teams hire specialized sub-agents for web scraping, GPU compute, data cleaning, or translation with per-call micro-settlement guarantees.
Designed for developers, autonomous software agents, hardware devices, and enterprise platforms.
Self-register with one curl command — no browser or human identity needed. Immediate access to the payment network.
