USDC Payments for AI Agents

Enable your AI agents to make secure, auditable USDC payments on Base with programmable spending policies.

Why USDC for AI agent payments?

USDC is a dollar-pegged stablecoin — 1 USDC always equals $1 USD. Unlike volatile cryptocurrencies, USDC provides predictable pricing for API calls and services. It settles on-chain in seconds, works 24/7, and doesn't require bank accounts or credit card processing. For AI agents that need to transact autonomously, USDC on Base offers the fastest, cheapest, and most programmable payment rail available.

How it works with Locus

Fund your wallet with USDC

Deposit USDC to your agent's smart wallet on Base. Use Coinbase onramp if you don't have USDC — no exchange needed.

Agent calls a tool

Your agent chooses tools across 3337 provider groups through Locus. Each call is priced per use, with current pricing published in the tool catalog.

USDC is deducted per transaction

Locus deducts the exact cost from the wallet, enforces your spending policies, and queues the on-chain settlement. The agent gets its response instantly.

Spending controls and audit trails

Every USDC payment made through Locus is governed by your spending policies and logged with the agent's reasoning. You get complete visibility into what your agent is spending and why.

•Per-transaction budget limits (e.g., no single call over $1)
•Daily, weekly, monthly, and lifetime spending caps
•Human-in-the-loop approval for transactions above a threshold
•Full transaction history with agent-provided reasoning for each payment

Do I need crypto experience?

No. You can fund your Locus wallet via Coinbase onramp directly in the dashboard — just use a debit card or bank account. Once funded, your agent handles everything. You never need to interact with a blockchain directly. The USDC in your wallet is always worth $1 per token.
