Zambo is live: Your first 3 AI lead searches are free\n\nHi [Name],\n\nYou asked for a tool that finds real, source-backed contractors without fluff. Zambo is ready.\n\nWe built this for one reason: to get you qualified leads in under 60 seconds. No guesswork. No manual scraping. Just verified prospects for your specific trade and city.\n\n**The Proof, Not the Promise**\n\nI don’t want you to take my word for it. I want you to see the engine work.\n\nI ran a live test for a web designer in Austin, TX. The system executed the search and returned a definitive status: **No source-backed leads found right now.**\n\nThat is the correct behavior. Zambo does not invent contacts to make the numbers look good. It returns only what the data supports. If the market is quiet, it tells you the market is quiet. That honesty is why you can trust the results when the leads *do* appear.\n\n**Get Your First 3 Searches Free**\n\nYou have 3 free searches per day. No credit card. No login required.\n\nPick your trade. Pick your city. See what’s actually out there.\n\n**Your Next Step:**\n\n1.  Go to [Link to Zambo]\n2.  Enter your trade (e.g., Roofer, Plumber, Web Designer)\n3.  Enter your city\n4.  Review the source-backed results\n\nThis is your chance to test the accuracy before you commit. If the leads aren’t real, I don’t want your business. If they are, I’d love to help you scale.\n\nLet me know what you find after your first search.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Link to Zambo]\n\n***\n\n*Note: The receipt for the Austin test case is available here: https://zambo.dev/run/6090a762-fde7-4aae-8233-9d2f9c608045*","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b75f50462228d03d97fb9f7d75dd087be723a86314cd089b8504b3c8c29a7b00","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:d258b9b0d3aa2c5dc8f9282b4ffad540c868ad386273dfca1345191828bf8cec","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":"sha256:8d73e5833bd34203b695db99ae01b3fe94003286af44637e6995afb6acc0d8b3","anchor":{"event_id":"d2b839ac7e019c252f3623f1b1add296b583466abf9760474b331cf0c9fcb46f","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-09T19:27:01.240Z","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":"2026-11-09T19:27:00.671Z","evidence_url":null,"receipt_uuid":"2e7c1696-d8c6-4a8c-a46a-c4fb208eae10","output_sha256":"sha256:bbe7ccd4e8543bf65d6d5efdde3a46631ec08fde5bd6da1b7ca1ba7d21926d26","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-09T19:27:00.671Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:bbe7ccd4e8543bf65d6d5efdde3a46631ec08fde5bd6da1b7ca1ba7d21926d26\",\"receipt_uuid\":\"2e7c1696-d8c6-4a8c-a46a-c4fb208eae10\",\"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":"2026-11-09T19:27:00.671Z","detail":"The receipt store reports 2026-11-09T19:27:00.671Z; 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.
