# Meterlane — USDC Payments for AI Agents and B2B Payouts

> Meterlane is metered USDC payment infrastructure — Agent Gateway for AI per-request payments and Stablecoin Corridor for fast B2B payouts on Base L2.

Meterlane is a dual-product payment infrastructure platform built on Base L2. Use **Agent Gateway** to monetize any HTTP API with per-request USDC micropayments that AI agents pay autonomously — no OAuth, no subscriptions, no human checkout. Use **Stablecoin Corridor** to quote and settle USDC into local fiat (BRL, MXN, NGN, KES, ZAR) for B2B payouts in minutes instead of days. Everything runs under a single org in the [Meterlane dashboard](https://meterlane.app).
