I just published nano-empire-tollbooth 0.3.0 on PyPI -- a Python SDK that adds Stripe-backed pay-per-call metering to any MCP server or AI endpoint.
One pip install and your API endpoint accepts micropayments. No subscription infrastructure, no billing portal, no token counting logic.
Built for the Model Context Protocol ecosystem: Trusted Publishing via GitHub Actions OIDC, x402 micropayments, Stripe Connect for revenue splitting, license-key gating.
$0 to start, $0.01 per call after. No monthly minimum, no setup fee.
