x402 (www.402bulls.xyz) is a lightweight API on the Base network offering a connectivity check and a direct on-chain NFT minting endpoint. The /api/ping endpoint provides a simple health/connectivity check for integrations, and /api/mint mints a unique NFT directly to a payer's wallet upon payment. Designed for low-cost operations ($0.001–$1), it’s suited for dApp backends, minting flows, bots, and prototyping without running bespoke minting infrastructure.
