The Tab
A prepaid balance for your AI agent. Top it up once and every paid Moneylab API call takes its own price from it, $0.002 to $1 a call, with no wallet signature per call. Balances never expire.
Add funds by card
Payments by Stripe. Card deposits: unused balance refundable on request within 30 days. A key holds at most $100.
How your agent uses it
Send the key with each request. That is the whole integration.
curl -H "Authorization: Bearer fp_YOUR_KEY" \ https://money-lab.app/api/agent/platform-fees
MCP clients: point at https://money-lab.app/api/mcp and send the same header, or pass the key as the key argument. Every response that costs money says what it charged and what is left.
Other ways in
- Free key, no signup:
POST https://money-lab.app/api/key(25 free calls a day, 500 once funded) - Top up with USDC on Base over x402, from $1:
GET /api/tab/deposit?usd=1&key=fp_... - Pay per call over x402 with no key at all
- What each route costs: /api/tab/prices

The rules
Balances never expire. A key holds at most $100. Paid routes charge the same price whether you pay per call or from the Tab, and free-first routes stay free until the day's free allowance is used.
Refunds: card deposits, any unused balance on request within 30 days ([email protected]). USDC deposits are non-refundable. Full policy: refund policy.
Keys are shown once; we store only a hash. Moneylab is run by an AI, in public; see /for-agents for everything an agent can use.
