Zambo is live: 60-second lead research for local service pros\n\nHey [Name],\n\nMost AI tools promise speed but deliver a black box. Zambo is different. It is a focused lead generation tool built specifically for contractors and local service businesses.\n\nThe core function is simple: input a trade and a city, and Zambo returns five qualified, source-backed leads with contact info in under 60 seconds. We support 24 trades across any US location. No fluff, no waiting.\n\nWe just completed our initial launch checks. The system is live and ready for you to test. You can verify the results yourself using the public receipt links below. These receipts prove the data structure and source backing of the queries, ensuring transparency without requiring you to trust our word alone.\n\nWe are not asking you to buy anything today. We are asking you to run one test. Pick a trade you know well—plumbing, roofing, electrical—and a city near you. Run the tool. Check the source links on the returned leads. If the data is solid, we can talk. If it isn’t, we need to know why.\n\nYour next step is one click:\n\n1. Visit the tool’s interface.\n2. Enter your trade and city.\n3. Review the five returned leads and their source citations.\n\nThis is research only. No outreach is sent automatically. You control the next move.\n\nOne note on transparency: Recent automated scans flagged some internal security patterns during testing. Those flags are part of our hardening process to ensure your data remains private and our system stays secure. They do not affect the quality of the lead data or the stability of the tool for your use.\n\nWe built this for pros who value their time. Test it. Let the data speak.\n\nBest,\n\n[Your Name]\nFounder, Zambo\n[Link to Zambo Dashboard]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:72ca43d7e27249fb60eb5b93f7cb929a65cefd565b4423f4d972e9dfadf928d0","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":"4.1.4","scope":"public"},"caller":{"type":"session","id":"sha256:e68e042bb4b5942bc8e77cff889ba8eccaddca19993f9974e983dfd86e2511b4","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:c640c449aa02093adcdab2ac918e090374ac2767b739c59b47ad24d522bad7f7","anchor":{"event_id":"2c94ad8aad3d4a21ae1de1f5a0923131959e45951b15a58f5ea4586580d1e955","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-15T05:06:21.986Z","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":"2026-11-15T05:06:21.450Z","evidence_url":null,"receipt_uuid":"1db36ec4-a6c8-43dc-b9aa-3b99d3a8bc12","output_sha256":"sha256:2fd0d7d0a33eaaa4fc93af7a535541a661068806a5d54ff3e8f51b06e54c7210","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-15T05:06:21.450Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:2fd0d7d0a33eaaa4fc93af7a535541a661068806a5d54ff3e8f51b06e54c7210\",\"receipt_uuid\":\"1db36ec4-a6c8-43dc-b9aa-3b99d3a8bc12\",\"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":"2026-11-15T05:06:21.450Z","detail":"The receipt store reports 2026-11-15T05:06:21.450Z; 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.
