Pricing
Simple access. Clear pricing.
A receipt is a public record of one tool call and the result Zambo observed. It does not prove the answer was right or that something happened outside Zambo.
Buy 24 hours of access for $0.99. It is a one-time purchase, not a subscription. Product and provider limits still apply.

Free access allows 20 free calls per metered tool each day; registered Signal agents allow 40. People use the one-time Day Pass checkout. Agents that need paid access follow the x402 request from the MCP endpoint. Product and provider limits still apply.
Extra receipts: $0.10 for a standard receipt, $0.50 for a detailed one.
How receipts are checked →How access works in practice
Zambo is one hosted connection for compatible AI apps. Add your Zambo link to the app you already use, then describe the task. A successful call returns its result and a public record you can open later.
The free path is intentionally low-friction: tool-specific free daily limits, no account, and no credit card. That gives a person or an agent a real call to inspect instead of a preview or a promise. The daily limit is per tool, and calls pause when the limit is reached; it resets on the daily schedule rather than silently charging the caller.
Details for developers
For people, the Day Pass provides 24 hours of access through the one-time Day Pass checkout. The monthly and annual Zambo Pass options are also human checkout. Agents use the separate x402 flow when more access is required; the server presents that request at the MCP endpoint. Product and provider limits still apply.
What the receipt gives you
A receipt is a public record of one tool call and the result Zambo observed. It gives you something to open after the chat has moved on or the work has been handed to someone else.
A receipt does not prove that an answer is correct or that an outside action happened. It only records what Zambo observed and saved.
Details for developers
Each receipt includes the tool name, timestamp, canonical record bytes, and output hash. The public verifier recalculates the hash; it checks whether the saved record changed, not whether the result is true.
Secondary receipts extend the same verification trail when a calling workflow needs additional receipt depth. The basic and deep options are listed as $0.10 and $0.50 per receipt. These are receipt records, not a replacement for the underlying tool result or for independent review of external evidence.
Agent access
Details for developers
Agents connect to the same MCP endpoint. If the free allowance is not enough, the endpoint can request payment through x402 on Base. This is separate from the one-time Day Pass checkout for people. Product and provider limits determine what a specific workflow can use.
Checking a result
Anyone can open a public receipt without paying. Running a new tool call follows the access options and product or provider limits listed above.
Choosing the next step
- Learning the connection: use the install guide, paste the hosted Zambo link, and run a real free call.
- Running a bounded workload: start with the free limit, then use the Day Pass when 24 hours of authenticated access to 138 tools is the right fit.
- Building a repeat workflow: compare the ongoing Pass options and keep the same connection connection and receipt trail.
- Checking a result: open the public record returned with the result. Technical checks are available in the receipt details.
Every option keeps the decision explicit. Zambo does not silently turn a paused free call into a paid call. A person chooses the access path, and the receipt gives the calling agent or reviewer a stable record of what followed.
