Browse premium APIs, pay with USDC or XLM on Stellar, and get instant access. Built for developers, AI agents, and automated workflows.
Each service is protected by the x402 payment protocol. Connect your Freighter wallet, call an endpoint, and pay only for what you use.
The x402 protocol turns HTTP 402 into a native payment flow. No API keys, no subscriptions.
Make a standard HTTP request to any paid route. The server responds with 402 Payment Required and payment details.
Your wallet creates a USDC or XLM payment on Stellar. The signed transaction is attached to the retry request.
The facilitator verifies the payment and the server returns the API response. Instant, one-call settlement.
Every service publishes structured metadata so AI agents and automation can discover, evaluate, and purchase API access programmatically.
