Zambo is live: 5 qualified leads in 60 seconds**\n\nWe stopped building. We started shipping.\n\nZambo is now live for contractors and local service businesses. The workflow is simple: enter a trade and a city. Within sixty seconds, you receive five qualified leads with verified contact information. The system supports twenty-four trades across any US city.\n\nWe designed this for precision, not volume. Every lead is source-backed. We do not guess. We do not scrape random directories. We pull verified data points that indicate active business potential. This is research, not outreach. You get the raw intelligence to craft your own approach.\n\nThe platform operates on a transparent free tier. You get one free first call per tool per UTC day. There are no hidden gateways or mandatory credit card entries to see the value. If the data isn’t useful, you walk away. If it is, you proceed.\n\nWe are launching with a focus on quality over quantity. Our initial scans in Austin for web design returned zero results, which is exactly what the tool should do when the market is quiet. We would rather tell you \"no\" than hand you a list of dead ends. This reliability is the core of the product.\n\n**Next Step:**\n\nRun your first scan. Choose a trade you know well. Pick a city where you have existing relationships or are considering expansion. Execute the search.\n\n[Start Free Scan](#)\n\nWe are watching the metrics. We are refining the filters. We are here to answer questions about the data sources and the filtering logic.\n\nUse the tool. See the data. Decide if it fits your workflow.\n\nThe door is open.\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:2af8942e64a666fa39e6034798b92aef9fbea0fd8be5988a9f19668016ad506f","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:a5fd249b646b66345304eac3a88757af35098f9af70f35f7a361f992b01a8eaa","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":"sha256:6f998cdd910b8d2212f3483849058bc0b037dc97b70a0a20cde9c6d30f8b0caf","anchor":{"event_id":"70b05b291365e7731d36726e33c882873f154c554c2e1f21f4810aa56fb1dc9e","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-13T06:17:35.793Z","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":"2026-11-13T06:17:35.265Z","evidence_url":null,"receipt_uuid":"8dfbfb99-6640-4334-9906-f895444c7fbf","output_sha256":"sha256:fdd7c98de140b17d83283363440c76916e20268998474727b9fdca740a802ded","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-13T06:17:35.265Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:fdd7c98de140b17d83283363440c76916e20268998474727b9fdca740a802ded\",\"receipt_uuid\":\"8dfbfb99-6640-4334-9906-f895444c7fbf\",\"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":"2026-11-13T06:17:35.265Z","detail":"The receipt store reports 2026-11-13T06:17:35.265Z; 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.
