The Agent Gateway for Your API
AI agents are the next wave of API consumers — but your infrastructure wasn't built for them. They can't authenticate, can't pay, can't discover your capabilities, and you can't tell them apart from bots.
LightLayer is the agent gateway: a standalone reverse proxy that makes any API agent-native. Put it in front of your API — zero code changes — and AI agents can discover, authenticate, pay for, and interact with your service automatically.
→ Agent Identity & Auth — Verify agent credentials, enforce scoped permissions, audit every action. Built on the IETF agent auth draft.
→ x402 Micropayments — Agents pay per-request with stablecoins via HTTP 402. No subscriptions, no API keys — just money for data.
→ A2A Discovery — Serve a machine-readable capability card at /.well-known/agent.json so agents find and understand your API automatically. Per Google's A2A protocol.
→ Agent Traffic Analytics — See which agents hit your API, what they do, what fails. The "Google Analytics" for AI agent traffic.
