Is Zambo worth it? Pick the plan that fits how you work

By Brennan Zambo · Published October 16, 2026

Short answer: Zambo is worth it if you want your AI to use real tools and leave a verifiable receipt of what it did. Start free, buy a $0.99 Day Pass when one job needs more, and choose the $29/month or $290/year Zambo Pass if you do this every week.

What you're paying for

One URL (zambo.dev/mcp) gives your AI hands (152 tools, no key), memory (continuity threads that work in any AI), and proof (a verifiable receipt for every Zambo-run call, in the open AER-1 format). Plans only change how much you can do, not whether you get receipts.

The three options

Free: $0

20 calls per tool per day, with a separate counter per tool that resets at UTC midnight.
Some tools are free with no cap, including capability_search, credithunt and day_pass_status.
Receipts on every successful call. The handover page, browser verify and Accept/Flag all work on Free.
A ProvibeCode audit teaser (provibe_audit).
For: trying Zambo, occasional checks, light personal use.

Day Pass: $0.99, one-time, 24 hours

Keep going past the free daily limits for 24 hours.
An agent can buy it itself with x402 (USDC on Base). A person can buy it by card or PayPal through day_pass_checkout_link.
No subscription.
For: finishing one big job today, or agents that hit a limit mid-run.

Zambo Pass: $29/month or $290/year

Ongoing access for regular work.
Full ProvibeCode audits included: 5 per month, with no separate audit price.
Pass features: private and unlisted handovers in handover_list (listing public handovers is free) and workflow_seal (closed jobs ready for durable export).
For: freelancers and agencies delivering client work, builders auditing code often, and anyone who buys a Day Pass several times a month.

Step by step: find your plan in five minutes

Connect free. Paste https://zambo.dev/mcp into your AI.
Do one real task. For example "audit my site". capability_search routes it to ghost_audit_site. Open the receipt.
Check your usage. Ask for zambo_limit to see calls left per tool and your tier.
Hit a limit mid-job? Buy a Day Pass (day_pass_checkout_link, or day_pass_activate for agents) and finish.
Doing that often, or delivering to clients? Move to Zambo Pass at /pricing/.

What you get on every plan

A verifiable receipt for each Zambo-run call, with a public link and a verify link.
A handover link for client delivery, with Verify all and Accept/Flag.
Cross-AI memory through continuity threads.
The honest limit: a receipt shows the saved output hasn't changed since the call. It doesn't prove the output is correct.

FAQ

Is Zambo free?

Yes, to start. Most tools are free up to 20 calls per tool per day, and some are free with no cap. Every successful call returns a verifiable receipt.

When should I buy the $0.99 Day Pass?

When one job needs more than the free daily limits. It lasts 24 hours and doesn't renew.

What does Zambo Pass add?

Ongoing access at $29/month or $290/year, 5 full ProvibeCode audits a month, and private and unlisted handover listing and workflow_seal.

Do audits cost extra?

No. ProvibeCode has no separate price: there's a free teaser, and full audits are included in Zambo Pass.

Can my AI agent buy access itself?

Yes. An agent can buy the Day Pass with x402 in USDC on Base, within its wallet policy.
