Overview
What is Nano Tab?
Set up agentic payments in one click
Nano Tab lets API, dataset, and content owners charge AI agents per call. Set a flat USD price per call and agents pay in USDC on Base, with no signup and no ETH needed for gas.
Key capabilities:
- Wrap an endpoint with a paywall in one command: unpaid requests get HTTP 402 with payment details, paid requests return 200.
- Keep 99.9% when self-hosting or 98% through the managed gateway, settled in USDC on Base straight to your wallet.
- One-click buyer setup: an agent wallet with a budget and per-call cap, plus a helper that handles the 402, pay, and retry loop automatically.
- Deploy to Cloudflare Workers or your own VPS with a public HTTPS URL.
- Every payment is risk-scored so an agent can pause itself or escalate to you.
There is no monthly fee and no lock-in; Nano Tab is not for card payments, subscriptions, or SaaS billing.
