Zambo is officially online, and the first run just proved it works.\n\nWe tested the engine against the Austin web design market. The result? Zero source-backed leads found right now.\n\nThat is actually the point.\n\nMost lead-gen tools spam your inbox with unverified numbers or scraped data that looks good on paper but dies in the field. Zambo takes the opposite approach. If it doesn’t have a source-backed prospect, it tells you so. A receipt proves the bytes saved; it does not prove correctness. But it does prove the system is transparent.\n\nHere is what you get:\n*   **Specific Trades:** Supports 24 trades and any US city.\n*   **Speed:** 5 qualified leads with contact info in under 60 seconds.\n*   **Transparency:** Free, no API key, no signup. 20 free calls per day across work tools.\n\nWe didn’t invent customers to make a demo. We ran a live check. It returned no results for that specific query at this moment. When results *do* appear, they are prospects, not guaranteed sales. They are starting points backed by data, not empty promises.\n\n**Your next step:**\n\nRun your own test. Pick a trade and a city you know well. Use the free tier. Verify the output.\n\n[Link: Try Zambo Free]\n\nNo credit card. No lock-in. Just a clear look at what the tool can and cannot do for your business right now.\n\nLet me know what you find.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:3de7f877258b35cbbe23cbcbba80e585d93e27c12c9fd31dbd916f7d9bccd55c","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":"sha256:35110dc4bf584fca00a5929bee7f9ce7a1032c5c194fef09238ba4ddf3bd83a4","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":"sha256:395bdd2060f8d7572ef62280dbc69fdd10724931c47029b1ae0d107e66e01ec5","anchor":{"event_id":"86f6c9d2fc02c278b8c5fd22b027cd544d7a09bb78db0c8ab3ced9546e6b49d1","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-03T23:30:32.611Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-03T23:30:31.893Z","evidence_url":null,"receipt_uuid":"443a39b2-5b03-4845-bb97-1e20915b081d","output_sha256":"sha256:e2aa071e9c6b7d14fd16d72653b877e265d1cd92849cc4c04324ba04a7570d63","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-03T23:30:31.893Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e2aa071e9c6b7d14fd16d72653b877e265d1cd92849cc4c04324ba04a7570d63\",\"receipt_uuid\":\"443a39b2-5b03-4845-bb97-1e20915b081d\",\"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":"2026-11-03T23:30:31.893Z","detail":"The receipt store reports 2026-11-03T23:30:31.893Z; 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.
