Zambo is live: 5 qualified leads in 60 seconds\n\nHi [Name],\n\nZambo is officially live.\n\nWe built this tool to solve one specific problem: finding qualified prospects for local service businesses without the usual manual research grind.\n\nHere is exactly what it does:\n\n1.  **Input:** You pick a trade (e.g., roofer) and a US city (e.g., Phoenix, AZ).\n2.  **Output:** It generates 5 source-backed leads with contact info in under 60 seconds.\n3.  **Scope:** Supports 24 trades and any US city.\n\n**The Proof**\n\nWe ran a test search for \"web design\" in Austin, TX. The system returned zero results because no source-backed leads matched that specific query at that moment. This is a critical feature, not a bug. It refuses to invent contacts. If it doesn’t find a verified prospect, it tells you.\n\nYou can verify this behavior yourself. The receipt below proves the system executed the search and returned empty results, demonstrating its commitment to data integrity over volume.\n\n[View Receipt: https://zambo.dev/run/287ca3d2-56b2-441d-a662-07742375aacc]\n\n**Why this matters for you**\n\nMost lead gen tools throw garbage at you to look impressive. Zambo only gives you what it can verify. This means your outreach time goes to actual prospects, not dead ends.\n\n**Next Step**\n\nTry it free. You get 3 searches per day per IP. No sign-up required.\n\n1.  Go to [Zambo URL]\n2.  Enter a trade and city you know well.\n3.  Check the source links for the returned leads.\n\nIf the data holds up, we are ready to talk about scaling. If it doesn’t, you owe me nothing but your time back.\n\nLet’s see if your first search hits.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Link to Zambo]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:52cc60e1e6e8b0c9fc593becd5b92e681e285fbfa293d648feef0dc2e0320f93","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":"sha256:5e764b722978c05776b1a86e3c8966349fa8026cbd6d2bebe99499fd3d5fe380","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:fe5fa1f7e72be1ed249c11a76bc0f28aeedecba4a15e6c8e84665d2294c07ca3","anchor":{"event_id":"f47da6f2fcb73c4b3fea59684739482d1aaaa1a1bd991091589846ab6a47ee19","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-10T01:00:23.832Z","published_at_semantics":"Relay confirmation time (accepted acknowledgement or exact-event read-back); not the signed event's created_at.","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-10T01:00:23.121Z","evidence_url":null,"receipt_uuid":"28501d0f-d9ad-4e47-a2ed-3828852a22d1","output_sha256":"sha256:bd131ca88e17c2b23cecec6d8f575da59f8fc2dc7972a785a85ef8bc350f7c58","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-10T01:00:23.121Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:bd131ca88e17c2b23cecec6d8f575da59f8fc2dc7972a785a85ef8bc350f7c58\",\"receipt_uuid\":\"28501d0f-d9ad-4e47-a2ed-3828852a22d1\",\"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":"2026-11-10T01:00:23.121Z","detail":"The receipt store reports 2026-11-10T01:00:23.121Z; 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.
