Zambo is live: The \"No Results\" report\n\nHi [Name],\n\nZambo is officially out of beta.\n\nWe built this specifically for contractors and local service businesses who are tired of guessing which leads are real. The platform scans public sources to identify prospects, not just names. It distinguishes between a verified opportunity and a dead end.\n\nI ran a live test this morning to verify the system’s integrity. I queried for web design leads in Austin, TX. The tool returned zero results.\n\nMost AI tools would hallucinate a list to please the user. Zambo did not. It returned a precise, source-backed \"no results\" status. That negative result is the feature. It saves you time by telling you *not* to pursue those leads because the data doesn't support it. The receipt proves the bytes saved are unchanged, ensuring the report is a factual snapshot, not a generated guess.\n\nZambo currently supports 24 trades across any US city. You get five qualified leads with contact info in under 60 seconds. The free tier allows three searches per day per IP. No API keys. No signup.\n\nThe core value isn’t just finding leads; it’s trusting the data. When the tool says \"no,\" it means \"no.\" When it says \"yes,\" you have the source to back it up.\n\nI am not asking for a sale today. I am asking for a test.\n\nPick a trade you know well. Pick a city. Run the search. If the results aren’t source-backed and actionable, delete the email. If they are, let’s talk about how to integrate this into your workflow.\n\nTo test it, use the universal entry point or the lead signal tool directly. Here is the direct link for the lead generation module: https://zambo.dev/tools/leadsignal\n\nOr, visit the dashboard to see the live market data: https://zambo.dev/today\n\nThis is a draft for your review. Do not send until you have replaced the placeholders with your specific recipient details and verified the links resolve correctly for your domain.\n\nBest,\n\n[Your Name]\n[Your Title]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:adbe79f09199906bfd7c7d2d02c199d1ec1c825f66016829ce5a505aed1865b8","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":"sha256:7a922c6a37559e849395f20000896e3dace404a587c0510d9fc93a6c215bcebb","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":"sha256:139dfd40c2d6755a5937e4c60195eb3f8bc84cc2fec957eb4ef8489af8a177c1","anchor":{"event_id":"c7bb20926906a16be5b820a3a6605be50e2eb733a3e55bd518e326945dbce95b","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-02T12:08:32.566Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-02T12:08:30.494Z","evidence_url":null,"receipt_uuid":"1d1f4ea4-01e1-4b1f-bdd1-f3d23b2f988c","output_sha256":"sha256:5277fd01d21d4aee3ad5c41be50dc9d2cdbb85b61d410b00175026fd83f8aab6","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-02T12:08:30.494Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:5277fd01d21d4aee3ad5c41be50dc9d2cdbb85b61d410b00175026fd83f8aab6\",\"receipt_uuid\":\"1d1f4ea4-01e1-4b1f-bdd1-f3d23b2f988c\",\"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":"2026-11-02T12:08:30.494Z","detail":"The receipt store reports 2026-11-02T12:08:30.494Z; 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.
