Zambo is live: 60-second lead research\n\nHi [Name],\n\nZambo is officially launched. We built it to solve one specific problem: finding qualified, source-backed leads for local service businesses in under 60 seconds.\n\nThe platform currently supports 24 trades across any US city. You input a trade type and location, and the engine returns up to five qualified prospects with contact information. This is not a generic scraper. It is a research tool designed to verify information against public sources before presenting it to you.\n\nWe are treating this launch phase as a test of the core workflow. Our initial execution plan targets specific niches, such as roofers in Phoenix or web designers in Austin. The system flags when no source-backed leads exist in a specific area, ensuring you never work with stale or unverified data. Each result comes with a receipt URL that proves the saved bytes were captured, though we advise you to verify the live status of each prospect before outreach.\n\nWe are not selling you a finished customer list. We are providing the infrastructure to generate accurate, actionable research on demand. The current free tier allows for three searches per IP per UTC day, with no authentication required for the initial tool calls.\n\nIf you want to test the workflow, here is your access:\n\n1.  **Visit:** https://zambo.dev\n2.  **Action:** Enter a trade (e.g., \"plumber\") and a city (e.g., \"Denver, CO\").\n3.  **Result:** Review the returned leads and their source citations.\n\nWe keep the process transparent. There are no hidden fees for the initial research calls. We want you to see the quality of the data before you decide to integrate it into your daily operations.\n\nTry the tool now. If the data quality meets your standards, let us know. If it doesn’t, tell us what’s missing. We are building this based on real-world usage, not assumptions.\n\nBest,\n\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:f6f8aeb282416d7b89b54a905676fb48532f5ab8523cd01fc0d08e77f7af3a7d","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":"4.1.4","scope":"public"},"caller":{"type":"session","id":"sha256:dbffc67f90b7ca655b442abdcfd213be4fa38e76b8b4cf5561bbf537953fe8d0","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:e6d9d2291d72189a9b808c76647e24bcb86ef9f2097ffe9a5862504d94908ab0","anchor":{"event_id":"707b2c5bcebe3d22299e1227625fdc2b511420c1720c9ebd8454d346ac5d6223","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-15T13:25:34.335Z","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":"2026-11-15T13:25:33.789Z","evidence_url":null,"receipt_uuid":"2e9639b2-abc4-4424-8c68-bd56a011c6f7","output_sha256":"sha256:75a0e58ae8fd7969f04c566212405953bd4b3bf3020e6ca2a50b8234cf90e9eb","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-15T13:25:33.789Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:75a0e58ae8fd7969f04c566212405953bd4b3bf3020e6ca2a50b8234cf90e9eb\",\"receipt_uuid\":\"2e9639b2-abc4-4424-8c68-bd56a011c6f7\",\"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":"2026-11-15T13:25:33.789Z","detail":"The receipt store reports 2026-11-15T13:25:33.789Z; 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.
