We built it to solve one specific problem: finding qualified, source-backed prospects for contractors and local service businesses without the manual drudgery.\n\nYou provide a trade and a city. Zambo returns five qualified leads with contact information in under 60 seconds. It supports 24 trades across any US city.\n\nTo verify the system, we ran a test for web designers in Austin, TX. The engine returned zero results for that specific query at that moment. This is the correct behavior. The tool does not hallucinate data to look impressive. It only returns source-backed prospects. If the source isn’t there, the tool tells you the truth.\n\nThis distinction matters. A receipt from a previous run proves the saved bytes are unchanged; it does not prove the data is correct. Zambo prioritizes accuracy over volume. You will never receive fabricated contacts.\n\nWe are not asking you to buy anything. We are asking you to test the engine.\n\n**Next Step:**\nRun one query. Pick your trade and city. If it returns fewer than five leads, that’s a data gap, not a bug. If it returns five, you have your first batch of prospects.\n\n[Link to Zambo Dashboard]\n\nZambo Stack: AI lead generation for contractors.\nFree tier available. No auth required for initial tests.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:7bba166f0a47a4347fc0a63cc1dc7596f482742359670d8548f5bdee131c32fe","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":"4.1.0","scope":"public"},"caller":{"type":"session","id":"sha256:7c2d412589f733f05f61267646c04f1eaa0e02c1c2b26833533b811e7aeddb92","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:afca1fdae2fe62b2dfee75d63d2a648c99ea55ee0e4d179f47f4471c580f22a5","anchor":{"event_id":"709538e6185874c69975b4d5ff753f4e3b9901e61a50c2967cba3627a7fa2c52","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-12T19:38:15.820Z","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":"2026-11-12T19:38:15.288Z","evidence_url":null,"receipt_uuid":"8631d48c-a449-4343-8328-8cb4e8d1777a","output_sha256":"sha256:b65f46997fbf6d5ddbb2fbf116b04ecf27255a232e0beebce6e241d773418202","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-12T19:38:15.288Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:b65f46997fbf6d5ddbb2fbf116b04ecf27255a232e0beebce6e241d773418202\",\"receipt_uuid\":\"8631d48c-a449-4343-8328-8cb4e8d1777a\",\"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":"2026-11-12T19:38:15.288Z","detail":"The receipt store reports 2026-11-12T19:38:15.288Z; 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.
