Zambo is live: 60-second lead gen for local trades**\n\nHey [Name],\n\nZambo is officially out. We built this specifically for contractors and local service businesses who need qualified leads without the agency markup or the software bloat.\n\nThe core promise is simple: give us a trade and a city, and we return five qualified prospects with contact info in under 60 seconds. It covers 24 trades across any US city. There’s no API key, no signup wall, and no hidden fees. You get three free searches per day per IP to test the waters.\n\nWe ran a live test for web design leads in Austin, TX. The system returned zero results for that specific query today, which is exactly how the tool behaves—it only delivers source-backed prospects, not padded lists. If you want to see the raw data from that run, here is the receipt proving the state of the search: https://zambo.dev/run/685b97f8-677a-42c2-b1ee-363a85658782\n\nNote that a receipt confirms the bytes saved by the system; it does not guarantee the quality of the leads themselves. You must verify the prospects. However, the speed is real. If you work in HVAC, roofing, or landscaping, you can plug in your city right now and see if the database has active signals for your trade.\n\nThis is not a customer list. It is a prospect generation engine. Treat the output as starting material for your own outreach strategy.\n\n**Your next step:** Copy this link into your browser and run a search for your primary trade and home city:\nhttps://zambo.dev/today/k/Vs-QZi-NNZVupzhksI6Hr-eLbT6Hi-c3Q1vskBntnN88G-iactPieOX78zimwhdAN7MINIn3prL8-DvVBoaFHOoIQoroOBMxgobGUMfAMddr-xE5lUFyQWijDRJE\n\nIf the results are relevant to your pipeline, you’re ready to scale. If they’re empty, you know the market saturation for that specific niche and location instantly. That data point alone saves you hours of manual digging.\n\nLet me know what trade and city you test first. I want to hear how the speed holds up against your current workflow.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo Stack","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:3855af105b7e1e3c59f0874b93620e45b138bac444520e86dcd09f995c6ca911","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:a9625152ffe35bbd3399867b0d6e58f1113133606a4d33a44c6376202f6a816f","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":"sha256:131a1ce7a33b71ff487dd1305887afa17f1024978f9cc8ea7e1d6816034a640e","anchor":{"event_id":"7f634e1f9476ec4cab5415b6dcd9e4fbea479842d1cbc776f2f48842597fc29a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-01T14:03:10.624Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-01T14:03:08.792Z","evidence_url":null,"receipt_uuid":"9f046029-9b74-4a75-84cf-a8b0c5ecfa9b","output_sha256":"sha256:7ae02d3370b3bbc7dd9b8764c705278125297a734741f2ce1ad5908c217a5d67","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-01T14:03:08.792Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:7ae02d3370b3bbc7dd9b8764c705278125297a734741f2ce1ad5908c217a5d67\",\"receipt_uuid\":\"9f046029-9b74-4a75-84cf-a8b0c5ecfa9b\",\"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":"2026-11-01T14:03:08.792Z","detail":"The receipt store reports 2026-11-01T14:03:08.792Z; 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.
