## Quick start
### Claude Desktop / Cursor / Codex
Add to your MCP config:json
{
"mcpServers": {
"apihub": {
"url": "https://mcp.apihub.io/mcp",
"headers": {
"Authorization": "Bearer ahk_your_api_key"
}
}
}
}
### APIHub CLIbash
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
