# Introduction

> Trustless agent payment authorization for the AI economy.

Delegare (Latin for "to delegate") is the first AP2-compliant payment authorization infrastructure for AI agents. It allows human users to grant spending power to AI agents by issuing Verifiable Digital Credentials (Intent Mandates), without ever handing over credit card numbers or private keys. Works with any AP2-compatible merchant globally. Runs on Stripe for fiat, Base for USDC/USDT.

## The Problem

AI agents today are limited by their inability to perform economic actions. Existing solutions require either:

1. **Full Custody:** Giving an agent your credit card or wallet seed phrase (massive security risk).
2. **Pre-funding:** Locking capital into a per-agent wallet (capital inefficient).

## The Delegare Solution

Delegare introduces **Intent Mandates** — cryptographically signed tokens that enforce strict spending limits, merchant allowlists, and time-based expirations.

## How it works

1. **Merchant** requests a setup session.
2. **User** authorizes limits (e.g., "$50/mo total, max $10 per tx").
3. **Agent** receives a `intentMandate`.
4. **Agent** calls `/charge` with the token whenever it needs to buy something.
5. **Vault** validates limits atomically and executes the payment on the best available rail.
