        "headers": {

  npx @apihubio/cli register   # get an API key
  npx @apihubio/cli topup 10   # fund with $10 USDC

Why credits instead of per-call x402

  • Gasless: pay on-chain once when topping up, not per request
  • Walletless: no USDC, no EIP-3009 signing, no gas
  • Works in any MCP client: just a Bearer token header
  • Instant: D1 debit at the edge, no block confirmations per call
