Apiosk
Sell API calls on a pay-per-request basis with instant settlement
Apiosk is a programmable payment layer that lets you sell API calls on a pay-per-request basis with sub-millisecond validation and instant settlement. It embeds an x402 payment proof into the HTTP header, removing long-lived API keys and reducing breach risk for AI-to-AI traffic. Developers can import endpoints from GitHub or an OpenAPI schema, choose networks like Base, Ethereum, and Polygon, and accept stablecoins such as USDC, USDT, and DAI. Use Apiosk to meter usage, prevent abuse, and monetize APIs without subscriptions.
