# AgisHub

> Pay-per-call tools for AI agents. No signup, no API keys — your agent pays a few
> tenths of a cent per call in USDC on Base via the x402 protocol. Free MCP tier for
> discovery and prototyping; pay-per-call HTTP (x402) for production.

## How it works

- Discover & try over MCP (free): `https://api.agishub.com/mcp` (or per service: `/mcp/<service>`)
- Pay-per-call over HTTP (x402): `POST https://api.agishub.com/v1/<tool>` (alias `/paid/<tool>`)
- Unpaid HTTP requests return an x402 `HTTP 402` challenge; sign the USDC payment on Base and retry.
- Machine-readable schema: `https://api.agishub.com/openapi.json`

## Payment

- Protocol: x402
- Network: Base (mainnet)
- Asset: USDC
- Authentication: none
- API keys: none
