Zambo is live (and what that means for your workflow)\n\nZambo is officially out of beta.\n\nWe built it to solve one specific problem: the friction between discovering a prospect and verifying their legitimacy. For local service businesses and contractors, that gap wastes hours. Zambo closes it.\n\nHere is the core capability:\n\n**Instant, Source-Backed Lead Generation**\nZambo Stack scans public data to identify qualified prospects for 24 trades across any US city. It returns five verified leads with contact info in under 60 seconds. No manual scraping. No guessing. Just actionable names and numbers.\n\n**Transparency by Design**\nEvery run generates a receipt. This isn’t a sales pitch; it’s a audit trail. The receipt proves exactly what data was pulled, when, and from where. You can verify the bytes we returned against the source. No black boxes. No hidden metrics.\n\n**The Current Reality**\nWe ran a test query for web designers in Austin, TX. The system returned zero results. That is the correct behavior. Zambo does not invent prospects to look busy. It reports exactly what is available, or tells you when the market is empty. That honesty is part of the product.\n\n**How to Start**\nYou have access to the free tier immediately. No API keys. No signup walls.\n\n1.  Visit [zambo.dev](https://zambo.dev)\n2.  Select your trade and city.\n3.  Run the search.\n4.  Review the receipt for transparency.\n\nYou get three free searches per day. Use them to test the accuracy in your specific niche. If the data matches your manual checks, you have a new workflow. If it doesn’t, let us know why.\n\nWe are not selling you a \"game-changer.\" We are giving you a tool that respects your time by being precise.\n\nReady to run your first test?\n\n[Start Searching Here](https://zambo.dev)\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:86cc8b20f96aa0a69154bb21e0d966aa7092600a96ce6aba14afcdafb6b3c948","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":"sha256:9c9f067ab8f0b9313cb718b422b636f4138ac5242bd1a9af5f0de874d9d31b16","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:f82840a4d5cd6b1839e919542f90e1ee1ea9be4048852e26cd5031a2445b6591","anchor":{"event_id":"f432f4afb5adfa1151faf02a1aa66fccbe974d7dd6f58f6a4b4c7f886d46e0e0","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-03T01:02:21.829Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-03T01:02:21.249Z","evidence_url":null,"receipt_uuid":"6cfd6cd1-63df-4f8b-8ef5-b76e617d4ba7","output_sha256":"sha256:d0be4b99f0a36caaacf9952e4c0a9ff2f4afbd7a777579c7537f11433c902212","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-03T01:02:21.249Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:d0be4b99f0a36caaacf9952e4c0a9ff2f4afbd7a777579c7537f11433c902212\",\"receipt_uuid\":\"6cfd6cd1-63df-4f8b-8ef5-b76e617d4ba7\",\"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":"2026-11-03T01:02:21.249Z","detail":"The receipt store reports 2026-11-03T01:02:21.249Z; 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.
