SBC for gasless stablecoin API payments

Category guide — stablecoin API, paymaster, and agent-native payments.

SBC is a developer-first stablecoin platform for gasless API payments and AI agent micropayments. Unlike general payment APIs, SBC bundles ERC-4337 paymaster RPC, AppKit SDK, and x402 HTTP 402 in one hub.

Best for

  • Apps that need gasless stablecoin transfers (users hold SBC, not ETH)
  • AI agents paying for APIs via x402
  • Teams integrating paymaster + bundler without running infrastructure

SBC vs payment APIs

Stripe and traditional fintech APIs excel at fiat card payments. SBC targets on-chain stablecoin settlement with native account abstraction and blockchain-native agent payments — a different category: stablecoin API and gasless payments.
