Modexia AgentPay is financial infrastructure that gives your AI agents their own USDC wallets, spending policies, and the ability to autonomously pay for any service on the internet — compute, APIs, data feeds, and more.

Your agent calls the Modexia SDK or MCP server to initiate a USDC transfer. The funds are sent from the agent's programmable smart-contract wallet on Base L2, settling in under a second with near-zero gas fees. No human approval is needed — spending policies enforce limits automatically.

USDC is a fully-reserved stablecoin pegged 1:1 to the US dollar, issued by Circle. Modexia uses USDC because it eliminates crypto volatility — your agent's $50 balance stays worth $50. It's the most widely accepted stablecoin for on-chain payments.

The Modexia MCP (Model Context Protocol) server lets AI agents like Claude invoke financial tools directly — check balances, send payments, and manage wallets — without writing any custom code. Just point your MCP-compatible agent at the server and it works out of the box.

Modexia charges 1% per transaction — that's it. No monthly fees, no setup costs, no hidden charges. You only pay when your agents make payments. The platform itself, including wallets, SDKs, and the MCP server, is free to use.

Yes. Every agent wallet is secured by Circle's Multi-Party Computation (MPC) infrastructure — private keys are split across multiple parties with no single point of failure. Spending policies enforce per-transaction, hourly, and daily limits, so even a compromised agent can't drain funds.

Modexia offers a Python SDK for direct integration, a REST API accessible from any language, and an MCP server for agent frameworks like Claude. TypeScript and JavaScript SDKs are coming soon.

x402 is an open-source standard for machine-to-machine payments over HTTP. When an AI agent hits a paywalled API that returns HTTP 402, the Modexia SDK automatically detects it, pays the invoice, retries the request with a payment proof, and returns the data — all in a single call.
