Mandate is the trust and authorization layer for autonomous agent commerce. When your AI agent encounters a paid API, Mandate verifies the agent’s identity, checks its spending policy, and either approves the payment or blocks it — in real time, before any USDC leaves the account.

Quick Start

Create your first agent and mandate in under 5 minutes.

How It Works

Understand the full x402 payment flow from challenge to proof.

Agent Developer SDK

Add the @mandate/sdk to your agent and handle 402 payments automatically.

API Seller Middleware

Protect your API endpoints with requireKyaPayment() in 5 lines.

What Mandate does

Every autonomous agent that makes purchases needs two things: an identity that sellers can trust, and a spending policy that its owner controls. Mandate provides both.
  • Agent registry — Register your AI agent and get a stable agent_id that sellers can verify
  • Mandates — Set per-transaction limits, total budgets, allowed merchants, and expiration dates
  • Policy engine — Every payment attempt runs through 9 real-time checks before approval
  • x402 support — Native support for the HTTP 402 payment protocol with USDC on Base
  • Audit log — Tamper-evident record of every policy decision and transaction

Who uses Mandate

You’re building an AI agent that needs to call paid APIs — data providers, compute services, tools that charge per request. Install @mandate/sdk, create an agent, attach a mandate, and your agent handles payments automatically without storing credentials.Start here: Agent Developer Guide
