402 is the answer. The Oracle is how you ask.

## Connect (free)
1. Set X402_PAY_TO to a 42-char Base address (receive-only).
2. Set X402_NETWORK=eip155:8453 and X402_FACILITATOR_URL=https://api.cdp.coinbase.com/platform/v2/x402 for mainnet.
3. Keep DEMO_MODE=true until HTTP 402 + MCP unpaid paths are green locally.
4. Public seller must show wallet_configured=false. Buyer key stays in ~/secrets.
5. After HTTPS deploy, POST CDP validate, then one seed settle so Bazaar can index.
6. Agents: MCP streamable HTTP at /mcp ; humans: POST /api/consult/oracle_ask after paying the 402.
