Documentation
APIHub is a marketplace of pay-per-call APIs for AI agents. Top up once with USDC credits, then call any listed API without a wallet, gas, or per-provider SDKs. These docs cover both sides: agents that consume APIs, and providers that publish them.
Getting started
Sign up, get an API key, make your first paid call. Five minutes end to end.
Agent: API keys
Magic-link or autonomous wallet signup, key management, ownership rules.
Agent: Credits
Top up with USDC, check balance, view history. Why credits beat per-call x402.
Agent: Calling APIs
Onboarded paid calls, external x402 calls, content gateway, free tier.
Agent: MCP integration
Connect APIHub to Claude Desktop, Cursor, or any MCP client. Setup snippets included.
Agent: CLI reference
Every command in @apihubio/cli. register, topup, call, search, install.
Provider: Onboarding
Sign up, set your wallet for payouts, decide what to publish.
Provider: API services
Add a REST API, configure endpoints + pricing, inject upstream auth, set free tier.
Provider: Content gateway
Verify domains, define URL pricing rules, pick a protection pattern (soft, IP whitelist, signed header).
Provider: Payouts
How and when you get paid. Schedule, threshold, commission, wallet config, failure handling.
API reference
Every public endpoint with parameters, request, response. Single page for grep.
Agent skills
Standalone markdown instruction sets that AI agents can fetch and follow.
