Zambo is live: get 5 qualified leads in 60 seconds\n\nHi [Name],\n\nZambo is officially live. We built it to solve one specific problem: finding qualified, source-backed prospects for local service businesses without wasting hours on manual research.\n\nHere is what you get:\n\n1. **Instant Lead Generation**: Input a trade and a city. Get five qualified leads with contact info in under 60 seconds.\n2. **Broad Coverage**: Supports 24 trades across any US city.\n3. **Free MCP Access**: One free first call per tool per UTC day, plus three shared continue calls. No authentication required.\n4. **Safe Research**: The tool returns source-backed lead research and draft messages. It does not send outreach. You remain in control.\n\nWe recently ran a test for web design in Austin, TX. The system correctly returned zero results for that specific query at that moment, demonstrating that it prioritizes data integrity over volume. If it cannot find source-backed data, it tells you so. No hallucinations. No fake contacts.\n\n**Your Next Step**\n\nWe have a free tier available. You can test the system today by running a query for your specific trade and city.\n\n1. Connect to Zambo via MCP.\n2. Run `leadsignal({trade: \"your_trade\", city: \"your_city\"})`.\n3. Review the five leads returned.\n\nIf the data matches your criteria, you have a ready-to-go prospect list. If not, you know exactly where to adjust your parameters.\n\nWe are not asking for a subscription. We are asking for a test run. If the leads are qualified, we have earned your attention. If they are not, you lost nothing but a minute.\n\nCheck out the live demo here: [Link]\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b95071873ca41cdee76d3b87dc0b8a0b03d548b68d7afe0cc5b9b12d1e25a745","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":"sha256:2fd0d9099882b9fa33356204ceefea2b5b6aa27d18e44168d5d21f43e1eff534","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:f85405bf04e17fdd19ef141eea0d5ef6ae539651d8b7347dc01a5b0e979d12d5","anchor":{"event_id":"f501f6612eea9dfe455050e0fa6c92eaeaf0a72e19e2ef1e14ebb9e518b82c76","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-15T21:05:33.576Z","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":"2026-11-15T21:05:32.611Z","evidence_url":null,"receipt_uuid":"9fa99fd1-e777-44fc-bdd0-cdc5cd08b20c","output_sha256":"sha256:e2417ccde26f40a24224886134e8957f6e31e8fe3ce444d74134b2fdd9c87e29","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-15T21:05:32.611Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e2417ccde26f40a24224886134e8957f6e31e8fe3ce444d74134b2fdd9c87e29\",\"receipt_uuid\":\"9fa99fd1-e777-44fc-bdd0-cdc5cd08b20c\",\"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":"2026-11-15T21:05:32.611Z","detail":"The receipt store reports 2026-11-15T21:05:32.611Z; 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.
