Direct answer

How much does a day of AI tools cost?

A day of AI tools on Zambo costs $0.99, paid once, for 24 hours of full access. There is no subscription to start and nothing that renews. If you work with AI tools most days, the Zambo Pass is $29 a month or $290 a year instead. Humans pay for either option by PayPal, or by card through PayPal, at zambo.dev/day-pass, and the full price list is at zambo.dev/pricing. That is the whole money answer: ninety nine cents for a day, twenty nine dollars for a month.

Start with the free check: run the live demo first and see a real job run with its receipt, at no cost. If the work in front of you needs a full day, the Day Pass is the $0.99 step after that.

The price, broken down plainly

Start with the arithmetic, because most AI pricing hides it. The Day Pass is one payment of $0.99 for 24 hours of full access to Zambo, the verifiable work layer for AI, through one MCP endpoint at https://zambo.dev/mcp. Full access means the same tool set a Pass holder uses: 153 tools in total, with 35 on the default surface and the rest available on the full surface. The clock runs for 24 hours from purchase, not to midnight, so a pass bought at 4 in the afternoon covers you to 4 the next afternoon.

The Pass is the ongoing option. It costs $29 a month or $290 a year, and $19 a month if you hold $ZAMBO. Divide the monthly Pass by thirty days and it works out close to the Day Pass price per day, which is the point: the Pass is priced for people who work this way most days, and the Day Pass is priced for everyone else. Neither price is a trial discount that jumps later. The Day Pass simply ends, and the Pass renews at the price shown on the pricing page.

What a day buys is a day of real work, not a look at a brochure. In that day your AI can research, write, check sources, audit a site, find leads, save memory you choose to save, carry work from one AI to another, and file a verifiable receipt for every job. Public handovers, the flagship way to hand finished work to a client as one link, are free to send and free for the client to open. Checking any receipt is free at zambo.dev/verify, with no signup, for you and for anyone you send work to.

Why the usual way costs more than it looks

The common way to buy AI help is a stack of monthly subscriptions. One plan for the AI you talk to, another for the tool layer, another for a specialist service, each one renewing on its own date whether or not you used it that month. The sticker prices are only part of it. The real cost is paying for thirty days to solve a problem that takes one day: a client job due Friday, a report due Monday, a site audit, a batch of leads, a handover packet for work already done.

Do not take invented numbers for that stack. Prices for products like ChatGPT and Claude change, bundles differ by country and by plan, and this page will not state a specific price for another product: check the current price on the product itself if you need one. The structural point holds at any sticker price. A monthly subscription charges you for the month. A day pass charges you for the day. If your need is a day, the monthly shape is the expensive shape, even before you count the second and third subscription in the stack.

There is a second hidden cost: switching and setup repeated under deadline. A subscription stack usually means separate accounts, separate logins, and work scattered across them. Zambo connects through one MCP URL, with no key, to the AI you already use, including ChatGPT, Claude, Claude Code, Cursor, Gemini, Grok, Codex, Copilot, VS Code, Windsurf, Cline, and Zed, and to frameworks such as n8n, CrewAI, and LangChain. One connection, one day, one record of what ran.

What one paid day actually covers

A useful way to judge the $0.99 is to list the jobs people actually finish inside a day. A freelancer clears a client deliverable and sends it as a handover link the client can accept or flag. A solo operator audits a website, fixes the findings that matter, and keeps a receipt for each check. A trades business runs leadsignal to find public posts from people asking for its work, then works that list while it is fresh. A writer researches a piece in the morning, drafts it in the afternoon, and checks every source before filing.

Each of those days has the same shape: a burst of connected work, a record of it, and then a natural stop. The receipt matters here, and it is worth stating exactly what it does. A verifiable receipt records one tool call and its saved result, and anyone can check it free. It proves the saved result was not changed after the fact. It does not prove the answer was right, and no honest tool should claim it does. What it gives a paid day is a trail: at the end of the day you can show what ran, in what order, with what result.

Continuity is part of the day too. Work saved in one AI can be opened in another AI connected to the same Zambo account and continued there, so the day is not trapped inside one app. Memory holds only facts you explicitly save, through memory_remember and memory_recall; it does not import your chats or guess at what to keep. For a one day job that crosses tools, say research in Claude, building in Cursor, and a summary in ChatGPT, that carrying is often the difference between finishing and restarting.

How to buy a day, step by step

Step one: open zambo.dev/day-pass and pay $0.99 once. Humans pay by PayPal, or by card through PayPal. There is no subscription created and no renewal to cancel later. Keep the confirmation the way you keep any receipt for a business purchase, especially if the day is for client work you will bill.

Step two: connect your AI to https://zambo.dev/mcp. It is one URL and no key. Add it in the AI or framework you already use, then ask for a small first job with a checkable result, so you can see a receipt appear and open it at the verifier before you trust the day to a deadline. Step three: work the list you came with, biggest job first, while the 24 hours are young. Step four: before the day ends, save what you want kept, send any handover links, and download or copy the records the job needs. The work products are yours; the pass ending does not take finished outputs back.

Agents pay differently, and the distinction matters for automated work. An agent pays USDC on Base through x402, per the payment request the endpoint returns, rather than through PayPal. That is the machine path to the same access: a person buys a day with PayPal, an agent buys with USDC on Base. If you run agents in tools like CrewAI or LangChain, plan which path each run uses before the run starts, so a job does not stall halfway on a payment question.

Day Pass or Pass: the honest dividing line

Buy days while your use is spiky. One client job this week, none next week, a research day the week after: that pattern costs a few dollars a month in Day Passes and nothing in between. Switch to the Pass when the pattern changes, when you notice you are buying passes most weeks, when private handover links and your own branding on the record matter, or when the work runs daily and stopping to buy a day would be friction. The monthly Pass at $29 and the annual Pass at $290 are listed side by side with the Day Pass at zambo.dev/pricing, so compare them there before deciding.

Run the simple test before you subscribe to anything, here or anywhere. Count the days in the last month when you actually did connected AI work, not days you opened an app out of habit. If the honest count is four or five, day pricing wins by a wide margin. If the count is twenty, ongoing pricing wins and the day shape would waste your time. Most subscription regret comes from skipping that count and paying for the person you meant to be instead of the work you actually did.

One day: $0.99 once, 24 hours of full access, no renewal.

One month: $29 on the Zambo Pass, for work that runs most days.

One year: $290 on the Zambo Pass, the lowest ongoing rate for daily users.

Free, always: the live demo, checking any receipt at the verifier, and opening a public handover someone sends you.

Who a priced day fits, and who it does not

A priced day fits the deadline worker: the freelancer with a deliverable due, the applicant finishing a work sample, the founder preparing a launch, the student or job seeker doing one deep research session, the small business owner who needs leads, an audit, or a month of content in one sitting. It also fits the skeptic, the person who has been burned by a subscription they forgot to cancel and now wants the bill to match the use, exactly.

It fits less well if your work never stops. A support operation, a monitoring job, or a team running agents around the clock will burn the day shape quickly; the Pass exists for them. It also fits less well if the job needs a specialist product Zambo does not replace: Zambo is a work layer your AI calls, not a substitute for the AI itself, your design suite, or your accounting system. Paying $0.99 does not remove the need for judgment about the outputs. The receipts record the work; you still decide whether the work is good.

Honest limits on the $0.99 day

Four limits, stated plainly. First, 24 hours is 24 hours: when the day ends, full access ends with it, and unfinished plans do not extend it. Second, free use exists around the edges, the demo and receipt checking are free, but a Day Pass day is the full access tier for that day, not an unlimited promise about every external service a job might touch. Third, a receipt proves a saved result was not changed after the fact, never that the result was correct. Fourth, prices on this page are the live Zambo prices as published at zambo.dev/pricing; prices for any other product are that product's to state, so check them at the source.

Frequently asked questions

How much does a day of AI tools cost on Zambo?

A day costs $0.99, paid once, for 24 hours of full access through the Zambo MCP at https://zambo.dev/mcp, with 153 tools in total and 35 on the default surface. There is no subscription and no renewal. Humans pay by PayPal or by card through PayPal at https://zambo.dev/day-pass/. Agents pay USDC on Base through x402. When the 24 hours end, full access ends, and anything you finished and saved in that day stays yours.

What is the difference between the Day Pass and the Zambo Pass?

The Day Pass is $0.99 once for one 24 hour stretch of full access, bought on the day you work. The Zambo Pass is ongoing access at $29 a month or $290 a year, and $19 a month for $ZAMBO holders. Buy days while your use comes in bursts, a client job here and a research day there. Take the Pass when connected AI work is part of most days and buying a day each time would just be friction.

Do I need a subscription to use Zambo for one day?

No. The Day Pass exists so one day of work does not require a subscription. Pay $0.99 once at https://zambo.dev/day-pass/, connect your AI to https://zambo.dev/mcp, and work for 24 hours. Nothing renews when the day ends. The live demo is free if you want to see a job run first, checking any receipt at https://zambo.dev/verify/ is free, and public handovers are free to send and free for a client to open.

How do agents pay for a day of access?

Agents pay USDC on Base through x402, following the payment request the endpoint returns, instead of using PayPal. Humans pay by PayPal or by card through PayPal. It is the same access through two payment paths, one built for a person at a checkout and one built for software that needs to pay on its own. Plan which path a run uses before it starts, so an automated job does not stall halfway on payment.

What happens when my 24 hours run out?

Full access ends. Work you finished stays finished: outputs you saved, handover links you sent, and receipts already filed remain checkable free at https://zambo.dev/verify/. What stops is starting new full access work. Buy another day when the next burst of work arrives, or move to the Zambo Pass at $29 a month if the bursts have become most days. There is no cancellation step, because there was never a subscription running underneath the day.
