It solves a specific bottleneck in your outreach workflow: finding qualified, source-backed prospects without manual scraping or guessing.\n\nHere is the one thing you need to know. Zambo connects to live industry data to identify specific businesses in your target city and trade. You input a trade (like roofing or HVAC) and a city. Within 60 seconds, you get five qualified leads with verified contact information. No authentication required. The system verifies that these are real, active businesses based on public records. It does not guess. It does not fabricate emails. It provides research you can trust before you dial.\n\nWe tested the initial build. The engine runs deep semantic analysis to ensure the leads match your specific service area. If a business isn’t verifiable, the system flags it or excludes it. You get clarity, not noise.\n\n**Try it now:**\n\nGo to [Zambo URL] and run your first search. Pick a trade you serve and a city where you want to grow. You have three free searches per day on the free tier. See the data for yourself.\n\nIf the leads match the quality of your existing book of business, you have a new channel. If not, tell us why. We are watching the feedback loop closely.\n\nNo account setup. No credit card. Just data.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:967c6d1ea0a480e769c4859e2fe6933cab3f3217a564cc43509935f3699bcb84","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:cf435191dc6ef703d951bd891ced948fb91835eeb16102859ae0c827c06b6153","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":"sha256:8b10ec5757a1c9ecf532570db69a30f92f2d10d8fe58c086c398bf32cb71601c","anchor":{"event_id":"72a8636df76e05d9feca39d821c2e4f3eecf0d8f39bc206d0ce44e7974b41496","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"failed","published_at":null,"retry":{"state":"scheduled","interval_seconds":960,"last_attempt_at":"2026-11-11T21:53:15.699Z","next_attempt_at":"2026-11-11T22:09:15.699Z","expected_completion":"No guaranteed ETA; relay acknowledgement is external."},"schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-11T21:37:23.006Z","evidence_url":null,"receipt_uuid":"ef5ae96f-7d73-4a03-a355-7bef393ad4a1","output_sha256":"sha256:4ece1b96e672b40c8ae09bcb880693bd1957bd8d913aa1a9f998f226bba3ea32","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-11T21:37:23.006Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:4ece1b96e672b40c8ae09bcb880693bd1957bd8d913aa1a9f998f226bba3ea32\",\"receipt_uuid\":\"ef5ae96f-7d73-4a03-a355-7bef393ad4a1\",\"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":"2026-11-11T21:37:23.006Z","detail":"The receipt store reports 2026-11-11T21:37:23.006Z; 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.
