We built this specifically for contractors and local service businesses who need qualified leads, not just contact lists.\n\nThe core promise is simple: You provide a trade type and city. In under 60 seconds, Zambo delivers up to five qualified leads with source-backed contact information. It supports 24 trades across any US city.\n\nTo prove the system works without inventing data, I ran a live test on LeadSignal, Zambo’s lead generation engine. I queried for web design prospects in Austin, TX. The system returned zero results. That is the correct behavior. Zambo does not hallucinate contacts or fabricate prospects to fill a quota. If there are no source-backed leads for that specific query, it tells you there are none.\n\nThis distinction matters. A receipt proves the saved bytes did not change; it does not guarantee the data is correct. Zambo prioritizes accuracy over volume. You get real, verifiable prospects or an honest \"no results.\" No fake names. No ghost numbers. Just clean data you can act on immediately.\n\nThe free tier allows three searches per day per IP. No authentication required. No credit card needed.\n\nI’d like to give you access to test this against your specific trade and service area.\n\n**Next Step:** Reply with your trade (e.g., roofer, plumber) and city. I will run a live search and send you the direct proof link with the results.\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:e2dc88ee7ed1634de56f3e79a4222f1beab280a4b23f362bc1e94cb6bfd7880e","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:af4e7d92e516426563a1d15cd8df19646965bbd7a51ad314f94b3a567f8faf53","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:b26ebbe18eeb6fa18779701a2b2824cd9f3619d655d16127bdb721e525235aa1","anchor":{"event_id":"12f3d5689edcb57e3c4b47c7df1af84372843d62b6cad53b449d8096b870308c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-07T08:19:42.714Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-07T08:19:37.555Z","evidence_url":null,"receipt_uuid":"306b94b9-2b93-4fa0-b7be-d461adffc655","output_sha256":"sha256:343304e80644b890752a14948b41a385f5a03fb41250b38c189bc47d9df4687e","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-07T08:19:37.555Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:343304e80644b890752a14948b41a385f5a03fb41250b38c189bc47d9df4687e\",\"receipt_uuid\":\"306b94b9-2b93-4fa0-b7be-d461adffc655\",\"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":"2026-11-07T08:19:37.555Z","detail":"The receipt store reports 2026-11-07T08:19:37.555Z; 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.
