## Overview

This repository is a source-linked guide to agentic AI payments, not the implementation of a payment service. Its documented user journey is to understand how an agent chooses a purchase, how a separate policy layer constrains or approves it, and how a payment can then clear. The README also branches into protocol and provider comparisons, a Pink sandbox example, and framework integrations. The tree contains no application source; relationships below reflect README statements, not inspected runtime calls.

Main entry points: [`README.md`](https://github.com/pink-agentic-payments/agentic-ai-payments/blob/main/README.md) (Agentic payments guide), [`docs/glossary.md`](https://github.com/pink-agentic-payments/agentic-ai-payments/blob/main/docs/glossary.md) (Payments glossary)
