Zambo is live: Test AI lead gen for Austin businesses\n\nHey [Name],\n\nZambo just launched. It’s a free AI tool that finds qualified leads for local service businesses in under 60 seconds.\n\nI ran a test search for web design firms in Austin, Texas. The tool returned zero source-backed prospects at this exact moment. That is the result. The system did not invent names, emails, or fake sales to fill the list. It strictly adhered to its source-backed constraint.\n\nThis is actually a strong selling point. Most AI lead tools hallucinate data to look impressive. Zambo returns empty results when the data isn’t there. You get accuracy over volume. For contractors and local service providers who need real contact information, not generated guesses, this reliability is the product.\n\nThe tool supports 24 trades across any US city. It requires no API key and no signup. You get three free searches per day per IP.\n\nI want you to verify this behavior yourself. I am not asking you to buy anything. I am asking you to run one search for a trade you know well in your local area.\n\n1. Go to the receipt link below.\n2. Note the specific trade and city used in the test.\n3. Run your own search using the Zambo interface.\n4. Compare the output.\n\nIf you find a source-backed lead, you have a prospect. If you find nothing, you have proof the tool is filtering for quality over quantity. Either way, you get to see the engine in action.\n\nThe link below is a permanent record of the Austin test run. It shows the query, the status (no_results), and the quota details. It proves the system is working as designed: strict adherence to source-backed data only.\n\n[Insert Zambo Search Link Here]\n\nLet me know what you find. If the tool holds up in your test, we can talk about how to integrate it for your team. If not, I’d like your feedback on what is missing.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Zambo]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:7245f7fec2d92007562627dfc834f5acfcd1590a1417d60d42786a0987eb3443","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":"sha256:458d3e7358122d3d77744a1a7bc2572dc92a678e9ff76fc2c340a0d1fd86d700","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":"empty","result_source":null,"evidence_source":null,"external_evidence":[],"provenance":{"result_source":null,"evidence_source":null,"evidence_status":"empty","evidence_captures":[]},"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:770e33e4a697a79c53dbf14477a81c7c6fa299df00db2bc0dabf5475bac6bce1","anchor":{"event_id":"f21cb69c02a4caf63ac1eeb09940b1f1597054bd5854fb85240de1e351a24796","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-05T16:59:00.146Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-05T16:58:54.115Z","evidence_url":null,"receipt_uuid":"375c5216-831c-4246-8153-22cb47f2928f","output_sha256":"sha256:fcf9c829beac2a4d44d2a2d7a147b00ebe01e8194bb73e98bb9df98297d565b2","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-05T16:58:54.115Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:fcf9c829beac2a4d44d2a2d7a147b00ebe01e8194bb73e98bb9df98297d565b2\",\"receipt_uuid\":\"375c5216-831c-4246-8153-22cb47f2928f\",\"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":"2026-11-05T16:58:54.115Z","detail":"The receipt store reports 2026-11-05T16:58:54.115Z; 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.
