Endpoint

POST https://brain-drain-iota.vercel.app/api/v/koza-l1-playbook/query

Same x402 spec the protocol uses everywhere. Drop into Claude Desktop / Cursor / any MCP client, or hit it raw with curl + a signed USDC tx.

Ask the vault

See the 402 quote live.

Drops a real x402 probe at /api/v/koza-l1-playbook/query. You'll get back the same 402 + payment requirements an agent would receive — no actual settlement until your wallet signs.
