Summary
Rodrigo Coelho, CEO of Edge & Node — the team behind The Graph Protocol, which has served 1.8 trillion on-chain queries since 2018 — and co-presenter Pranav Maheshwari introduce Ampersend, a compliance and spending-controls layer for AI agent payments, at AI Engineer World’s Fair.
The talk frames agentic payments as a fundamental infrastructure gap: traditional payment rails were designed with humans in the loop making authorization decisions, but AI agents transact at machine speed around the clock with no equivalent control layer. Before any enterprise-scale agentic economy can function, Coelho argues, a compliance layer must exist to verify counterparty sanctions status, identity, and transaction legitimacy — the same checks that govern the existing quadrillion-dollar global financial system. Edge & Node draws on prior art from a 2021 micropayment system built for The Graph, and has been contributing to the x402 specification since its Coinbase release in late 2024.
The demo portion shows a direct comparison between Claude Code with the Ampersend skill file installed versus a standard Claude Code instance, using a real-world task of finding the contact details of Mastercard’s head of crypto and blockchain. The standard agent hits a wall and returns a guess at an email format; the Ampersend-equipped agent autonomously pays for access to premium MCP tools in the background and returns specific verified data. The session positions Ampersend’s marketplace and skill-file approach as an aggregator that handles payment to paid MCP servers transparently, with enterprise budget guardrails and full transaction observability built in.
