Locus for Developers | Policy-Governed Agent Payments
DocsStart free

Agents don't shop like humans.They pay at machine frequency.

The demo everyone pictures is an agent booking dinner: one purchase, one approval, a human tapping yes. Real agent workloads are hundreds of metered tool calls an hour. Locus is the payment rail built for that — rules set once, enforced on every transaction, no tap required.

The Thesis
The demo everyone pictures
Book me dinner Friday.
Table for two at 7pm — $45 deposit. Approve?
Tap to approve

One purchase. One tap. The human is still the payment rail — the agent just fills the checkout form. This is the human economy with an agent bolted on.

412 transactions before lunch.One needed you.

Machine-frequency spending, metered per call, every transaction checked against your policy before it executes — and every one carrying the agent's own stated reason.

You can't tap yes at machine frequency. Policy is the only rail that scales.

Agents are becoming autonomous

Payments need to be governed. Locus turns financial access into a programmable primitive for AI agents: identities, limits, approved vendors, required justification, and complete audit logs.

Beyond payments, agents can use pay-per-use tools from 3337 providers (AI models, data providers, search engines) from a single Locus wallet, without opening an account with any of them.

Agents execute freely. The rules stay immutable.

The Locus System

Five pillars. One wallet.

One unified USD balance that reaches any SaaS or external tool — no extra accounts, no subscriptions to manage. No custodial vault holding your money, and no tap-per-charge. Your agent gets one consistent tool surface.

Agent wallets

Non-custodial ERC-4337 smart wallets — you hold the keys, so Locus can't spend, freeze, or lose your money. Agents get scoped session keys, not your credentials. No KYC, and Locus sponsors all gas.

Spending controls

Global allowances, per-transaction budgets, and approval thresholds — enforced at the wallet, before execution. An out-of-policy transaction isn't disputed after the fact. It never happens.

Auditability

Every payment carries the agent's own stated reasoning. The trail on your dashboard explains why your agent spent, not just what it spent — receipts for intent, not only amounts.

Pay-per-use agent tools

Approved tools your agent calls without ever creating a provider account, metered at each endpoint’s published price or usage basis. Custom HTTP APIs plug in through x402.

Vertical tools

Existing SaaS rebuilt agent-native and pay-per-use — full-stack deployment, checkout, and more stateful services over time.

Pay-per-use agent tools

3337 tool providers. Zero subscriptions.

Give your agent tools for AI models, data, search, maps, and more. Each tool is paid per use from its Locus wallet, with no provider accounts or API keys to manage.

How it works

Three steps to an agent that pays its own way

01

Fund wallet

Deposit USDC to your agent's non-custodial smart wallet on Base. Your funds stay in your control — Locus never takes custody.

02

Set rules

Define spending limits, per-transaction budgets, approval thresholds, and vendor allowlists. Policies are enforced on every transaction.

03

Agent pays

Your agent autonomously pays for tools and services — all within the guardrails you set. Every transaction is auditable.
