Zambo Receipt Bot
The Zambo Receipt Bot collects, verifies, and files a verifiable Zambo receipt for every job your bots do, on Grok or any AI with MCP, then sends a short nightly digest of links. Your bots work all day; in the morning you get one short message with the receipts for everything they did, each one checkable by anyone, free.

What it does
Bots finish jobs and report success in a sentence. The Receipt Bot turns that sentence into a record. For every job your bots do, it collects the receipt for the work, verifies it, and files it, so each job ends with a verifiable Zambo receipt at a public URL: what ran, what came back, saved when it ran and checkable later at zambo.dev/verify by anyone you share the link with.
It works on Grok or any AI with MCP, because the receipts come from the Zambo MCP (https://zambo.dev/mcp, 153 tools total, 35 on the default surface) rather than from any one chatbot. The bot is the collector and the filing clerk; Zambo is the verifiable work layer underneath it.
How to start
Two links are the whole setup. The landing page, zambo.dev/receipt-bot, walks through what the bot does and what it needs. The bot itself lives at https://x.ai/bot/AXD8poR15Ozom1w8jJrcm: open it, connect it to the bots whose work you want filed, and let it collect from the next job onward.
There is nothing to install on your own machines and no dashboard to learn. The output you live with is the digest, and the receipts it links to.
An example: a job filed, a digest in the morning
Say your bot runs a research job in the afternoon: a dozen lookups, a summary written, a file produced. As each part runs through Zambo, its receipt is created. The Receipt Bot collects those receipts, verifies each one, and files them under the job. The next morning your digest arrives: a short message naming the job and linking its receipts, like this real filed record: a worked example receipt.
Open a link and you see the job as recorded, not as summarized. Forward the digest to a client or a teammate and they can check the same links free, with no account, which is what makes the digest more than a status message: it is the work, filed.
Pricing
The Receipt Bot runs on Zambo, so pricing is the Zambo canon. A Day Pass is $0.99 one time and covers 24 hours. The Zambo Pass is $29 a month or $290 a year, and $19 a month for $ZAMBO holders. Humans pay by PayPal or card through PayPal; agents pay USDC on Base via x402. Checking any receipt the bot files is free at zambo.dev/verify, for you and for everyone you send the digest to. See full pricing or start with a Day Pass and let one day of bot work file itself.
Honest limits
The bot files receipts for jobs that run through Zambo-connected tools. Work a bot does entirely outside that path leaves no receipt for the bot to collect, and the honest description of such a job is unrecorded, not recorded and lost. A filed receipt proves the saved result was not changed after the fact; it does not prove the bot's work was correct, complete, or wise. The digest is a filing of records, and reading them, like reading any work report, is still your job.
Frequently asked questions
What does the Zambo Receipt Bot do?
It collects, verifies, and files a verifiable Zambo receipt for every job your bots do, on Grok or any AI with MCP, then sends a short nightly digest of links. Each receipt is a public record of a job's work, saved when it ran, that anyone can recheck free at https://zambo.dev/verify/. You wake up to one short message covering everything your bots did, with the proof attached as links.
How do I start using the Zambo Receipt Bot?
Open the landing page at https://zambo.dev/receipt-bot/ for the walkthrough, then open the bot itself at https://x.ai/bot/AXD8poR15Ozom1w8jJrcm and connect it to the bots whose work you want filed. From the next job onward, receipts are collected, verified, and filed automatically, and the nightly digest starts arriving. There is nothing to install on your own machines.
What does the nightly digest look like?
A short message naming each job your bots finished and linking the verifiable receipt filed for it. Open a link and you see the work as recorded: what ran and what came back, fixed when it ran. Forward the digest and the recipients can check the same links free with no account, so the digest works as a report you can hand to a client or a teammate.
What does the Zambo Receipt Bot cost?
It runs on Zambo pricing. A Day Pass is $0.99 one time for 24 hours. The Zambo Pass is $29 a month or $290 a year, and $19 a month for $ZAMBO holders. Humans pay by PayPal or card through PayPal; agents pay USDC on Base via x402. Checking any filed receipt is always free at https://zambo.dev/verify/ with no signup.
Does a filed receipt prove my bot did good work?
It proves the work was recorded as it ran and that the saved result was not changed after the fact. It does not prove the work was correct or well judged; a receipt for a bad job is still a faithful record of a bad job. What changes is accountability: claims about what a bot did can be checked against filed records instead of taken from the bot's own summary.
