Zambo is live: 60-second lead generation for local trades\n\nHi [Name],\n\nZambo is officially launching. It solves one specific problem: finding qualified, source-backed prospects for contractors and local service businesses without the guesswork.\n\nThe tool, LeadSignal, takes two inputs—trade type and city—and returns five qualified leads with contact information in under 60 seconds. It supports 24 trades across any US city. The key differentiator is accuracy: Zambo does not invent contacts. It only provides data backed by public sources. A receipt proves the saved bytes remain unchanged; it does not guarantee the correctness of the underlying data, but it ensures transparency in what was delivered.\n\nCurrently, the free tier allows three searches per day per IP with no authentication required. Recent tests indicate that while the system is fully executable, results depend on available public data for the specific trade and location. For example, a recent query for web designers in Austin, TX returned zero source-backed leads, highlighting that the tool prioritizes verified data over volume. This is a research tool, not an outreach engine. It drafts messages but never sends them.\n\nIf you are looking to streamline prospect discovery for a specific trade in a targeted city, this is the tool to test. It handles the heavy lifting of data aggregation and draft generation, leaving you to focus on the conversation.\n\nWe are looking for early adopters who value data integrity over speed. If you want to see how LeadSignal performs for your specific industry, grab a free search.\n\n[Link to Zambo]\n\nBest,\n\n[Your Name]\n[Your Title]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:145cbb4e400d4607135516e163cc18bf07a1d18b6d158749714cad223901c383","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":"4.1.0","scope":"public"},"caller":{"type":"session","id":"sha256:80a04c1145b95c66d20b0d4e352c335bcb8d0194ab3418f3b2a6d74de9667bf3","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":"sha256:00ef740bc840b43aec67edf47966acfb7b8c184996bdf0529be45084cec37b1c","anchor":{"event_id":"d613408d05d84bcad7b756d73ddb2a246d6d47e406a3223a95d8b9683e720102","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-12T01:59:59.017Z","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":"2026-11-12T01:59:53.671Z","evidence_url":null,"receipt_uuid":"1168f9ed-0d8b-421a-8108-000122f77090","output_sha256":"sha256:3592e722a816ef3850fcb3413ce2d209e3f8b410fa293c181dd303d45ca3d6f3","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-12T01:59:53.671Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:3592e722a816ef3850fcb3413ce2d209e3f8b410fa293c181dd303d45ca3d6f3\",\"receipt_uuid\":\"1168f9ed-0d8b-421a-8108-000122f77090\",\"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":"2026-11-12T01:59:53.671Z","detail":"The receipt store reports 2026-11-12T01:59:53.671Z; 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.
