Zambo is live: Proof over promises\n\nI stopped writing “fast-paced world” emails. I started building tools that show their work.\n\nZambo is now public. It is a research and verification engine for AI products. It does not guess. It executes specific checks and provides unalterable receipts for every action.\n\nMost AI tools hide their logic. Zambo exposes it.\n\nWe tested this against a critical security scenario. A simulated prompt injection attempt flagged a 100% risk level. The system detected the jailbreak, identified the attack vector, and blocked the malicious intent. It did not just say “safe.” It provided a semantic analysis, a pattern match count, and a timestamped receipt proving the block occurred.\n\nThis is the core value: **Verifiability.**\n\nWhether you are using `substrate_breakthroughs` for research or `leadsignal` for market data, every output comes with a `receipt url`. That URL is a cryptographic anchor. It proves exactly what data was returned, when, and how. A receipt confirms the saved bytes. It does not interpret them. It simply proves integrity.\n\nWe ran a lead generation test for web designers in Austin, TX. The tool returned zero leads. It did not invent names. It did not hallucinate contacts. It returned a `no_results` status with a clear explanation and a receipt. That honesty is the product.\n\nYou can verify every claim I just made.\n\n**Try Zambo today.**\n\n1.  Go to [zambo.dev](https://zambo.dev).\n2.  Run a basic search using `capability_search`.\n3.  Click the receipt link in the response.\n4.  Inspect the raw execution plan.\n\nIf you cannot verify the output, you do not own it. You just trust the black box. Zambo gives you the key to the box.\n\nThe free tier includes unlimited read-only research calls. No credit card. No fluff. Just data with a paper trail.\n\nCheck the engine.\n\nBest,\n\n[Your Name]\nFounder, Zambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:bc24132845bdfcc8d279fd50affc911194ab1519d046e715abfa8a3dec629eb9","input_hash_layout":"zambo-json-sorted-keys-utf8-v1","free_used":0,"free_remaining":0,"free_limit":0,"signal_handle":null,"tool":{"name":"write","version":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:c065b19defff30ca45779457d2caf2c6aff6b3c06b1fbc973c2837fae1ab9abb","label":"zambo-home-demo","label_source":"caller_reported"},"side_effects":{"declared":["none"],"schema_version":"zambo-side-effects/1","declaration_hash":"sha256:45aad38f3aa982b9aafe92ecb416ebe98791eddbaf8ab6df0bd08605b7c1bfee"},"evidence_sha256":null,"evidence_url":null,"evidence_byte_length":null,"evidence_content_type":null,"evidence_source_url":null,"evidence_status":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:ff40b45470f3a82448060a4518b894f22c6fea38e207cc1d9c864632e22ee380","anchor":{"event_id":"a8eab95045bb0805cd6afe0b76bdaeb22de900b0d235afe8ad9db874b2ce8806","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-24T07:19:07.781Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-24T07:19:07.244Z","evidence_url":null,"receipt_uuid":"e60bd4c1-0106-4497-bf97-b88326d066d8","output_sha256":"sha256:dce31297f44386d1d72e23860faf318de5dbaa3a7ff39465459cd57a07a55870","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-24T07:19:07.244Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:dce31297f44386d1d72e23860faf318de5dbaa3a7ff39465459cd57a07a55870\",\"receipt_uuid\":\"e60bd4c1-0106-4497-bf97-b88326d066d8\",\"schema_version\":\"zambo-receipt-anchor/1\"}"},"receipt_profile":"zambo-hosted-receipt/1","schema_url":"https://zambo.dev/aer-1/hosted-profile.schema.json","api_version":1,"verification_scope":"separate_sha256_commitment_and_provenance_binding_checks","checks":{"commitment_matches":{"label":"SHA-256 commitment","passed":true,"status":"pass","detail":"The exact decoded canonical bytes match the stored SHA-256 output hash."},"canonical_payload_matches":{"label":"Canonical payload reconstruction","passed":true,"status":"pass","detail":"The stored output and known call context reconstruct the exact canonical bytes."},"provenance_binding":{"label":"Provenance claim binding","status":"pass","passed":true,"detail":"The metadata claim is consistent with the verified receipt bytes; issuer is not authenticated."},"metadata_binding":{"label":"AER-1 metadata hash","status":"pass","passed":true,"detail":"metadata_hash matches the canonical metadata block."},"signature":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"No Ed25519 signature or pinned signing key was checked."},"chain":{"label":"Receipt chain (not checked)","passed":false,"status":"not_checked","detail":"No append-only receipt-chain proof was checked."},"issued_by_zambo_dev":{"label":"Issuer authentication","passed":false,"status":"not_checked","detail":"A zambo.dev receipt URL does not authenticate the issuer; no pinned signature or trusted issuer key was checked."},"immutable_log_timestamp":{"label":"Stored timestamp","passed":true,"timestamp":"2026-10-24T07:19:07.244Z","detail":"The receipt store reports 2026-10-24T07:19:07.244Z; immutability is not checked here."},"receipt_schema_version":"0.4","signature_valid":{"label":"Ed25519 signature (not checked)","passed":false,"status":"not_checked","detail":"Compatibility field only.
