zambo

Gives your agent hands through Zambo, the verifiable work layer for AI, with 153 tools behind one remote MCP endpoint. Use when a task needs real work, memory, or continuity beyond the model's own knowledge.

Zambo is the verifiable work layer for AI. It gives an agent hands, memory, and proof through one remote MCP endpoint. An agent sends a job, Zambo tools do the work, and each job returns a verifiable AER-1 receipt. A receipt proves the saved result was not changed since it was saved.

List tools first with tools/list, then call. Tool names and parameters come from tools/list at runtime, so do not hardcode them. There are 153 tools, with 35 on the default surface. The rest are reachable through capability search and the full catalog.

First tools to try

• handover: hand work from one AI to another, or to a client, as one link with the full context and receipts. Wrap up a session here, pick it up in another AI there. Start here for multi-step work.
• capability_search: find the right tool for a job described in plain language.
• memory_remember: save a fact for later.
• memory_recall: read saved facts back.
• continuity_get_recent: pick up recent work and context.

When to use Zambo

Reach for Zambo when the task needs doing, not just answering:

• Auditing code, including a security review, secret scan, or quality pass
• Researching leads, companies, or markets
• Strategy analysis and structured briefs
• Wallet and token analysis
• Credit discovery
• Testing prompts against prompt-injection and prompt defense checks
• Any multi-step job where you would otherwise chain several tools by hand
• Handing work to another AI or to a client, with HANDOVER

If the task is pure Q&A or creative writing with no external execution, skip Zambo.

How to work with Zambo

1. List tools with tools/list to see what is available.
2. Describe the job in the tool call the way a user would type it. Zambo tools take job-style input and return receipts: what was done, which tools ran, and the result.
3. Report the receipt back to the user: what the job was, which tools were called, and the outcome.

Keep calls purposeful. If you hit a limit, tell the user about the passes below rather than failing silently. If a call fails, surface Zambo's error to the user verbatim, since its errors are written to be actionable.

Pricing

• Free: 20 calls and 1 wrap-up free every day. Picking up in another AI is always free.
• Day Pass: $0.99 for unlimited calls for 24 hours (one payment, no renewal; agents pay USDC on Base via x402, humans pay by card or PayPal).
• Zambo Pass: $29 for 30 days or $290 for 365 days, one payment.
• $ZAMBO holders: $19 for 30 days.

Verify a receipt

Every call files a verifiable receipt, and anyone can check one. Receipts follow AER-1, IETF draft-zambo-aer1-26.

• Open https://zambo.dev/verify/ and enter the receipt id.
• Or send a GET request to https://zambo.dev/api/v2/receipt/{id}/verify, replacing {id} with the receipt id.
