Here it is.\n\nI’m skipping the fluff. Zambo is officially live.\n\nWe built this to solve one specific problem: finding qualified, source-backed leads for local businesses in under 60 seconds. No guessing. No scraping dead data. Just verified prospects.\n\nHere is the reality check from our first live test.\n\nI ran a query for web designers in Austin, TX. The result? Zero leads.\n\nDoes that sound like a failure? No. It’s a feature.\n\nZambo doesn’t hallucinate names or fabricate contact info to make you look good. It returns nothing if it can’t prove the data is real. That “no results” status is the exact same mechanism that protects you from wasting hours on dead ends. When we do find leads, they are backed by source data, not AI guesses.\n\nThis is the standard we are holding ourselves to. Accuracy over volume. Verification over volume.\n\n**What this means for you:**\n\n1.  **No Fake Data:** If we can’t verify it, we don’t send it.\n2.  **Fast Checks:** You get a definitive yes or no in seconds.\n3.  **Free Tier:** 3 searches per day, no signup required.\n\n**Your Next Step:**\n\nDon’t trust this email. Test it yourself.\n\nGo to [Link] and run a search for a trade you know well. Check the receipt. See if the data holds up. If it fails, tell us. If it works, you know why we’re different.\n\nStop paying for lead lists that are 40% outdated. Start using a tool that admits when it doesn’t know.\n\nSee you in the inbox,\n\n[Your Name]\nZambo Team\n[Link to Zambo.dev]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:4ba2ec44098de30dc351e91bef797102c4472bdb36c029e02cb863b85bf2d772","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":"sha256:9217cdd493f3f6bd1f25c9fa3492db5fe4f59612504f70cd37355315520eba94","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":"sha256:34e64148755dbe08174e0dffd87f9631a6792fdc3c881e49c6f53dc935c04beb","anchor":{"event_id":"991a4facd8c83e25f5bf397679d3c0f7ac427f1da45cb620daa7e9e8b8fb5b18","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-04T09:33:11.996Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-04T09:33:09.165Z","evidence_url":null,"receipt_uuid":"dd64a696-d157-4dd1-b1b3-53599d50e689","output_sha256":"sha256:e46de88e537a17eb70ea22097e7c4c386349ca7206ce5ab786a1c431bc5f3ad0","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-04T09:33:09.165Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e46de88e537a17eb70ea22097e7c4c386349ca7206ce5ab786a1c431bc5f3ad0\",\"receipt_uuid\":\"dd64a696-d157-4dd1-b1b3-53599d50e689\",\"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":"2026-11-04T09:33:09.165Z","detail":"The receipt store reports 2026-11-04T09:33:09.165Z; 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.
