The tool supports 24 trades across any US city. It returns five qualified leads with contact information in under 60 seconds.\n\nHere is what you can verify right now:\n\n1.  **No Signup Required:** No API keys or accounts needed.\n2.  **Free Tier:** Three searches per day per IP.\n3.  **Immediate Access:** Use the link below to run a live test.\n\n**How to test:**\n1.  Click the link.\n2.  Select a trade (e.g., HVAC, Plumbing) and a city.\n3.  Review the results.\n\n*Note: If no results appear for a specific city/trade combination, it means no source-backed leads were found at that moment. The tool does not guess or fabricate data. A receipt confirms the exact bytes returned, proving consistency, not necessarily the quality of the lead.*\n\nThis is a research tool, not an outreach sender. It provides the raw data; you decide the next step.\n\n[Link to Zambo Lead Generation Tool]\n\nLet me know if the interface is clear or if you hit any technical hurdles during your first search.\n\nBest,\n\n[Your Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:01bd7ab8eb58cc5ac49a3a8a6f57ef082ac82a25719d50b32f1a13bbf2a1b36b","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:ca921b122a50111d810a673d7efcc11fc1ff133403319fdeb1b03a617773f6eb","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:cb44f5874418c43ca209d0d8dff54f74e7082af6c95991e295fe91d1c7fa608f","anchor":{"event_id":"cbfa8a5d3ebc4f78b90f5f7aaa46da17c4d01822756d3f3caebfa2b007e81baf","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-01T00:24:41.256Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-01T00:24:40.716Z","evidence_url":null,"receipt_uuid":"f37d4b4a-7e0c-412d-abf8-d68935ca23cf","output_sha256":"sha256:ea7d61a4e79e39107f9cb83a3320b2c9ffe7c8e5bba99aa5c9719052dd449613","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-01T00:24:40.716Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:ea7d61a4e79e39107f9cb83a3320b2c9ffe7c8e5bba99aa5c9719052dd449613\",\"receipt_uuid\":\"f37d4b4a-7e0c-412d-abf8-d68935ca23cf\",\"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":"2026-11-01T00:24:40.716Z","detail":"The receipt store reports 2026-11-01T00:24:40.716Z; 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.
