The Problem
There are 10,000+ MCP servers. Most are hobby-quality because developers can't earn from them. Agents can discover tools but can't pay for them. There's no commerce layer.

The Solution: Agent Bazaar
A billing proxy that sits between agents and MCP servers. Providers set pricing, agents pre-fund balance, every call is metered with sub-cent precision.
# 1. Discover tools (no auth required)
curl https://noui.bot/api/bazaar/catalog
# 2. Call any tool through the billing proxy
curl -X POST https://noui.bot/api/bazaar/proxy \
-H "Authorization: Bearer bz_your_key" \
-d '{"tool_name":"wallet.balance","input":{"wallet":"0xAgent1"}}'
# 3. Check your usage
curl https://noui.bot/api/v1/bazaar/usage/summary \
-H "Authorization: Bearer bz_your_key"Live now: 14 tools · 6 providers · 10% platform fee · Sub-cent metering · Stripe Connect payouts
TypeScript SDK
npm install @forthebots/bazaar-sdkimport { Bazaar } from '@forthebots/bazaar-sdk';
const client = new Bazaar({ apiKey: 'bz_your_key' });
// Discover tools
const { tools } = await client.catalog.list();
// Call a tool (metered + billed)
const result = await client.tools.call('wallet.balance', { wallet: '0x...' });
console.log(result.meta.cost_cents); // $0.05
// Check balance
const { balance } = await client.balance.get();For MCP Server Providers
