Summary
Connects Claude to APIHub's paid API marketplace, letting you search, browse, and call metered APIs using prepaid USDC credits instead of managing wallets or gas per request. You get nine tools: search and list services, fetch service details, make paid calls to onboarded or external x402 APIs, read gated web content, and manage your credit balance. Useful when you need to orchestrate calls across multiple paid data sources without wiring up individual provider SDKs or handling per-call blockchain transactions. Authentication is just a bearer token, and debits happen instantly at the edge against your prepaid balance.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

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
