Getting Started

MicroAPI Hub implements the x402 payment protocol on Solana, enabling paid API access with on-chain receipts.

What is x402?

x402 is an open standard (inspired by HTTP 402 Payment Required) for pay-per-use APIs. Clients receive pricing requirements, complete a blockchain payment, and get access with verifiable receipts.

Architecture

Facilitator: verifies and settles payments on Solana
Provider API: serves resources using x402 requirements/responses
Web UI: discovery, pay, receipts, docs
