Zambo is live: 60-second lead generation for local trades**\n\nHi [Name],\n\nZambo is officially live. We built it to solve one specific problem: finding qualified, source-backed prospects for local service businesses without the guesswork.\n\nThe platform supports 24 trades across any US city. The core promise is speed and verification. You provide a trade and a location; Zambo returns five qualified leads with contact information in under 60 seconds.\n\nWe prioritize accuracy over volume. Our system relies on source-backed research, meaning we only present data we can verify. We do not invent contacts. We do not scrape unverified databases. If we cannot find a source-backed lead for a specific query, the tool returns zero results rather than filling the gap with low-quality data.\n\nThis approach ensures that when you do get a lead, it is a genuine prospect worth your time. The current free tier allows for three searches per day per IP address, with no authentication required. This is designed for immediate testing and validation.\n\nWe have completed the launch checks. The system is operational, and the receipt for this launch run is available for your review. Note that a receipt confirms the execution of the saved bytes and the integrity of the process; it does not guarantee the correctness of the underlying data, but it does prove the system functioned as designed.\n\n**Next Step:**\n\nI recommend running a single test query to validate the output against your current pipeline. Pick a trade you are actively targeting and a city where you have existing knowledge of the market. Compare the returned leads against your current sources.\n\nIf the data aligns with your expectations, we can discuss scaling your search volume. If not, we need to refine the source parameters before you invest further time.\n\nLet me know if you want to run that test now or if you prefer to review the launch receipt first.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Link to Launch Receipt]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:67e6f91bf6e4d50c417642ae34dcc98a963e6b99e33e58ed3c4fb0de3296968c","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":"sha256:2716cd1a620bf2d6d245828afbff3bddceeffaa5ece90a9560ee317c47a20343","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":"sha256:7ac824fad3153355ec52441db24abfe533efb35bb14ed66918f5f38169be5f04","anchor":{"event_id":"47aee5a545cf408415912d2944d67211daeac6928bfc9735659670039140e455","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-08T11:30:05.541Z","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":"2026-11-08T11:30:04.896Z","evidence_url":null,"receipt_uuid":"c712b21e-60da-4ec6-a213-b5b63fc2a363","output_sha256":"sha256:c6e2a378113e654bd26fac9b4139d83d43650870de177eaf3fde883d28445df5","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-08T11:30:04.896Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:c6e2a378113e654bd26fac9b4139d83d43650870de177eaf3fde883d28445df5\",\"receipt_uuid\":\"c712b21e-60da-4ec6-a213-b5b63fc2a363\",\"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":"2026-11-08T11:30:04.896Z","detail":"The receipt store reports 2026-11-08T11:30:04.896Z; 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.
