Quick start

Claude Desktop / Cursor / Codex

Add to your MCP config:

{
  "mcpServers": {
    "apihub": {
      "url": "https://mcp.apihub.io/mcp",
      "headers": {
        "Authorization": "Bearer ahk_your_api_key"
      }
    }
  }
}

APIHub CLI

npx @apihubio/cli install    # writes the MCP config for you
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
