Zambo is live: LeadSignal for local service businesses\n\nHi [Name],\n\nZambo’s first product, LeadSignal, is out today. It generates qualified, source-backed leads for contractors and local service businesses in under 60 seconds.\n\nThe tool supports 24 trades across any US city. You get five qualified leads with contact info per search. There are three free searches per day per IP, and no authentication is required.\n\nWe ran a test query for web designers in Austin, TX, and it returned zero results. The system correctly identified that no source-backed leads existed for that specific niche and location at that moment. This confirms the tool’s integrity: it does not invent contacts or hallucinate data. If a lead isn’t backed by a public source, it isn’t returned.\n\nThis matters because accuracy is the only metric that matters in lead generation. A receipt proves the saved bytes are unchanged, but it is the source verification that proves the lead is real. LeadSignal prioritizes verifiable data over volume.\n\nYou can test the tool right now. Go to the Zambo dashboard, select your trade and city, and run a search. If the tool finds leads, you’ll have their contact info in seconds. If it doesn’t, you’ll know immediately why. No guessing, no fake data, no wasted time.\n\nThis is a research tool. It does not send outreach emails or messages. It gives you the raw material to build your own outreach strategy.\n\nTry it with a trade you know well. See how the source-backed data compares to what you’ve been using. If it’s better, keep it. If it’s not, let me know specifically where it missed.\n\nThe free tier resets daily. Use the three searches carefully. Start with a high-volume trade in a major city to see the full capability.\n\nLet me know what you find.\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:0ab9a7d7c27a374e32123b749c9f68cd03fa865385bc3dcbdbd44a377c51b034","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":"4.1.0","scope":"public"},"caller":{"type":"session","id":"sha256:f3a0b65608bc3637f783df2a893de9123bb96b3a4d8244e731145f0e5e74d061","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:d450fcc47e63283d0d2c15cdedec23a4ba0c45292c03c241f4a2a625f9b04f95","anchor":{"event_id":"d90a5558b8a9461cde7dbbb1ee812140a2d8ff7dc1a17637a0faa2259330d529","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-11T16:10:19.890Z","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":"2026-11-11T16:10:19.361Z","evidence_url":null,"receipt_uuid":"bad7eb3e-3476-4835-a1c6-75a4dd404ed2","output_sha256":"sha256:281e97fb9cc186c0906ad3f43082abcf8467d04734f580704ab2aba121fc993f","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-11T16:10:19.361Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:281e97fb9cc186c0906ad3f43082abcf8467d04734f580704ab2aba121fc993f\",\"receipt_uuid\":\"bad7eb3e-3476-4835-a1c6-75a4dd404ed2\",\"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":"2026-11-11T16:10:19.361Z","detail":"The receipt store reports 2026-11-11T16:10:19.361Z; 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.
