Pricing · Zambo MCP
Pricing that fits how agents actually work
No seats. No monthly minimums for a program that runs eleven calls on a Tuesday and none on Wednesday. Start free, pay only when you need more — and every call, free or paid, returns a verifiable receipt.
Free — $0, forever to start
20 calls per tool per day. No account, no credit card. Connect one MCP server and run your first real call in minutes. Every call returns a verifiable receipt you can inspect, share, or build on.
Day Pass — $1.49 / 24 hours
24 hours of full access for less than a coffee. Pay with PayPal, card, or USDC on Base. A practical way to run a real workload end to end while your work stays on one Zambo trail.
Zambo Pass — for ongoing work
- Monthly — $49. Ongoing access through one MCP connection, plus the listed pass entitlements.
- Annual — $399. One year of Zambo Pass access with the same entitlement set.
- $ZAMBO holder — $29/mo. Verified holders of $10+ in $ZAMBO get the Pass entitlement set at the holder price.
Receipts, itemized
Every call returns a verifiable receipt. Need receipts beyond your plan's included depth? Secondary receipts are $0.10 basic / $0.50 deep per receipt, on all plans.
FAQ
Is the free tier really free?
Yes. 20 calls per tool per day, no account, no credit card. It is a quick way to see a verifiable receipt with your own eyes.
What does the Day Pass include?
24 hours of full access from the moment you start it. The exact entitlements are listed on the Day Pass page — that page is the source of truth, and we link to it rather than duplicate it.
What happens when I hit the free limit?
Your calls pause until the daily limit resets, or you start a Day Pass. Nothing is ever charged without you choosing it.
How do I pay?
Pay with PayPal, card, or USDC on Base.
What is a verifiable receipt?
A tamper-evident record of what the execution layer actually did: the tool called, the inputs, the outputs, and a hash you can recompute. Read the execution receipt guide.
