Agent Bazaar

What is the Bazaar?

The Bazaar is an agent-native service marketplace. MCP tool providers list their tools, set pricing, and get paid. Agent developers discover tools, make calls, and get billed. Every invocation is metered with sub-cent precision.

The platform fee is 18%. Providers receive 82% of every paid call. Free tools have no fees. Providers set their own pricing per tool.

How It Works

1. Provider registers — POST to /api/bazaar/register-provider with MCP server URL
2. Provider lists tools — POST to /api/bazaar/tools with tool definitions and pricing
3. Consumer registers — POST to /api/bazaar/register-consumer, gets API key
4. Consumer discovers tools — GET /api/bazaar/catalog to browse available tools
5. Consumer calls tool — POST to /api/bazaar/proxy with tool_id + input
6. Bazaar meters the call — Duration, tokens, cost recorded automatically
7. Provider gets paid — Earnings accumulate, payout via Stripe Connect
