{"query":"true","tools":[{"rank":1,"name":"doc_intel","description":"Analyze readable UTF-8 text or manage a private, resumable file-analysis job. Public text URLs are bounded to 1 MiB; pasted text to 60,000 UTF-16 code units and the complete MCP JSON request to 64 KiB. Private files require an active Zambo capability key and stay in private App Storage; use job_action=create, upload_url, upload_complete, part, status, pause, resume, cancel, review, delete or list. Files are limited to 25 MiB; PDFs to 200 pages; ZIPs to 20 MiB compressed, 50 MiB expanded, 100 text entries and 100:1 expansion. PDFs, images, archives and private repositories are not executed. Scanned pages/images require explicit Groq OCR consent, billed to Zambo with no separate user charge; exact provider USD cost is unavailable. Each analysis part covers at most 24,000 UTF-16 code units; file jobs resume after reconnect, lock source revisions, do not advance failed parts, and require complete range reconciliation and owner review. For larger text jobs keep the same _session_id, continue with offset and expected_source_sha256, collect every range and review before synthesizing. Groq fallbacks use the existing provider account, not a paid overflow service. When unavailable, YOU (the connected AI) can analyze the signed source range and submit host_analysis with host_handoff_token using this same tool. A pending handover is not completion and spends no free call; submission is labeled host-AI reported, never independently verified. Use analysis_mode=host_ai to skip Zambo inference entirely. Your AI's own plan still applies.

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.

Anchor status "published": Published to all configured relay targets.

Relay publication is separate from receipt integrity. When the original signed event is available, Zambo retries pending, partial, or failed anchors about once a minute. Relay acknowledgements are external, so there is no guaranteed completion time; the receipt remains checkable from its saved bytes and verification link.

Check this hash yourself

Receipt commitment: commitment matched; issuer, signature and chain not checked. This checks the saved bytes, not whether the answer was correct. Recompute the SHA-256 commitment in your browser. Open the API v2 JSON response to inspect the machine-readable checks. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
