Zambo is live: Fast, source-backed lead gen 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 contractors and local service businesses without the usual manual research grind.\n\nThe core promise is speed and accuracy. You provide a trade type and a city; Zambo returns five qualified leads with contact info in under 60 seconds. It supports 24 trades and any US city.\n\nWe are currently in a free research phase. There is no signup, no API key, and no cost to test the engine. You can run up to 3 free searches per day per IP.\n\nTo see the output quality, you can try the demo interface directly. For example, a recent query for \"web design\" in Austin, TX returned zero results today. That is a valid outcome: it means the system is filtering out weak or unverified data rather than padding the list with generic spam. A receipt ID generates a permanent proof of the bytes saved during that run, ensuring transparency on what was found and when.\n\nWe are not claiming to have fixed every database in the country. We are providing a precise tool for identifying high-potential targets that are backed by real-world data points. If the data isn’t there, the tool tells you so.\n\n**Next Step:**\n\nWant to test your specific market?\n\n1.  Go to [Link to Zambo Demo/Signup Page].\n2.  Enter your primary trade (e.g., Plumbing, HVAC, Roofing).\n3.  Enter your target city.\n4.  Run the search.\n\nCheck the results. Are the contacts relevant? Is the speed acceptable?\n\nLet me know if the output matches your current prospecting standards. If it does, we can discuss how to integrate this into your daily workflow. If not, tell me where it fell short so we can refine the filters.\n\nThanks,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:adcaf524a9391b669556a1c3c99b68a97bcbc334b59f84a5e72ae67f063b18e0","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":"sha256:1aff9953a79f3a02746d5955f9ef66f3abfe340baedda5b48a5fe16ea32ec393","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:a2d83df9fa63c7792797e233c1ff48a359e220c8db1064d23608b9112fb14094","anchor":{"event_id":"30b928127099afc9c8e9dac569d3561757b0e7f3cdbf7be22ec4abcd98dc8438","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-01T06:11:28.377Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-01T06:11:27.779Z","evidence_url":null,"receipt_uuid":"9d2611d5-04af-4aeb-9bf4-9af075727db0","output_sha256":"sha256:3112e73aec8f24126da0dfddbed5497027bfab259d3ceda66e3a97d54aa1b34c","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-01T06:11:27.779Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:3112e73aec8f24126da0dfddbed5497027bfab259d3ceda66e3a97d54aa1b34c\",\"receipt_uuid\":\"9d2611d5-04af-4aeb-9bf4-9af075727db0\",\"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":"2026-11-01T06:11:27.779Z","detail":"The receipt store reports 2026-11-01T06:11:27.779Z; 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.
