Zambo is live: 60-second lead research for local trades\n\nHi [Name],\n\nThe wait is over. Zambo is officially launched, and the first feature pack is ready for your trade.\n\nWe focused on the bottleneck stopping most contractors and local service businesses: finding qualified, source-backed prospects without manual scraping. Zambo Stack solves this by connecting your AI agent to live data. You provide a trade type and a city; we return five qualified leads with contact info in under 60 seconds.\n\nThis isn’t a generic directory. It’s a research engine. It supports 24 trades and any US city. Critically, it distinguishes between verified data and noise. A receipt proves the saved bytes remain unchanged, but the value lies in the speed and accuracy of the initial pull. You get a draft message attached to each lead, ready for your review.\n\nRight now, the system is processing real-time queries. For example, a recent search for web design in Austin returned zero source-backed leads at this moment. That’s the point. Zambo tells you when the market is quiet so you don’t waste time chasing ghosts. When it finds them, they are ready for outreach.\n\nYou can start with one free call per tool per UTC day. No auth required. No credit card. Just trade and city inputs.\n\n**Next Step:**\nReply with your primary trade and target city. I’ll run the first LeadSignal query for you and share the results, including any available drafts, directly in this thread.\n\nLet’s see what’s out there for your business today.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b9daef740fc4c7068c03510e4875d0a85dec2f4a07e26fc8c316e693301248f1","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:ba609763ea59295a9f2987a3ee1434c984238deae3b849389e43548c272911a5","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":"sha256:4ef31dc86b9bece63e0137ab13f9600747e297753e8fdd5fc1d435c61f8dd25b","anchor":{"event_id":"406d215271484983fa4cd6db379b509bc73e235a911f4018af9c2d358f045f01","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-13T20:37:38.271Z","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":"2026-11-13T20:37:37.744Z","evidence_url":null,"receipt_uuid":"e95b6d61-17c9-4e23-b130-1f6924e11574","output_sha256":"sha256:e41827d47f008cccd077ec4116d7ff198fb96e4dbce7c2677d15f3440b2f4860","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-13T20:37:37.744Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e41827d47f008cccd077ec4116d7ff198fb96e4dbce7c2677d15f3440b2f4860\",\"receipt_uuid\":\"e95b6d61-17c9-4e23-b130-1f6924e11574\",\"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":"2026-11-13T20:37:37.744Z","detail":"The receipt store reports 2026-11-13T20:37:37.744Z; 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.
