Zambo is live: 60-second lead generation for local trades\n\nHi [Name],\n\nNo pleasantries. Just the news: Zambo is officially live. It solves one specific, painful problem for contractors and local service businesses: finding qualified leads in under 60 seconds.\n\nThe tool takes a trade and a city. It returns five source-backed prospects with contact info. No fluff, no guesswork. We tested it against Austin, TX for web design, and the system correctly returned zero results because no source-backed leads existed in that exact query at that moment. That precision matters. You don’t pay for hallucinations or empty promises. You pay for verifiable data.\n\nZambo supports 24 trades across any US city. It runs on a transparent, free tier with no API keys, no signup hurdles, and no hidden costs. The interface is clean, the speed is instant, and the output is actionable. Whether you are a solo plumber in Dallas or a marketing agency serving fifty HVAC clients in Phoenix, the workflow remains identical: input, wait, execute.\n\nWe built this to cut the noise out of lead gen. Most tools drown you in unqualified data. Zambo gives you the signal. If the data isn’t there, the tool tells you that clearly. If it is, you have the contacts to start the conversation.\n\nWe aren’t asking for a long-term commitment. We are asking for a test.\n\n**Your next step:**\n\nRun one search. Pick your primary trade and your most active city. Use the free tier. Check the results. If the leads are qualified, we know we’ve solved a real pain point. If not, tell us exactly why.\n\nHere is your direct access link: [Insert Link]\n\nNo sales pitch. No follow-up spam. Just a tool that works.\n\nLet’s see what it finds for you.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:2fc7d81a546d2f25c65f40de54e8a1ba41b086ce20173b906a3f803ed7671f23","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:ec66aaa55766fec1e294eea006afba5f37d91bb25ecee5095dbf97eb48d43ef4","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:c70e167572509b0c87879a87a1051abff9639856e8afacd9d28f226832a71f32","anchor":{"event_id":"c61699008c2a1ba7b9402cb6bcfb1c94c30afea52e1839416489a957e8b380b6","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-31T02:03:12.425Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T02:03:11.857Z","evidence_url":null,"receipt_uuid":"d379bb8e-3aa0-4ba2-83cd-7a69b6fae9fc","output_sha256":"sha256:9e2224c553b6ae222c269004169724e0eec2a1cc7463e9867988d02f46fc389f","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T02:03:11.857Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:9e2224c553b6ae222c269004169724e0eec2a1cc7463e9867988d02f46fc389f\",\"receipt_uuid\":\"d379bb8e-3aa0-4ba2-83cd-7a69b6fae9fc\",\"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":"2026-10-31T02:03:11.857Z","detail":"The receipt store reports 2026-10-31T02:03:11.857Z; 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.
