Zambo is live: 60-second lead generation for local businesses**\n\nWe just flipped the switch on Zambo Stack.\n\nNo more manual scraping or guessing which contractors actually need AI tools. Zambo pulls qualified, source-backed leads for 24 specific trades in any US city. You get five contacts with verified details in under 60 seconds.\n\nWe’re keeping this light on fluff and heavy on utility. Right now, the platform is running on a free tier: three searches per day per IP, no signup, no API keys, and no hidden fees. It’s built for contractors and local service businesses who need immediate visibility into their local market without the enterprise overhead.\n\nWe tested the Austin web design sector during our final checks. The system correctly identified that no source-backed leads were currently available for that specific query, returning a clean \"no results\" state rather than inventing data. This matters. Zambo prioritizes accuracy over volume. If a lead isn’t verified in public sources, it doesn’t appear. You get real prospects, not a list of dead ends.\n\nThe infrastructure is live and stable. Our semantic analysis and pattern checks are running deep, filtering out noise and ensuring that every output respects strict safety and privacy protocols. We aren’t selling you a promise; we’re handing you a working tool that respects the integrity of the data it returns.\n\n**Next Step:**\nTest the engine yourself. Head to the Zambo dashboard, select a trade (like plumbing or roofing), and enter a major US city. You have three free searches available immediately. Verify the speed. Check the quality. See if the data matches your reality.\n\nIf the results align with your needs, we’re ready to scale. If not, you’ve lost sixty seconds, not a dollar.\n\n[Link to Zambo Dashboard]\n\nBest,\n\nThe Zambo Team\nZambo Stack | AI Lead Generation","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:ae82b1c0cec2eadd5d622f3e0ab84aa6613e72044749deef1d11e396eb9292c7","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":"4.0.0","scope":"public"},"caller":{"type":"session","id":"sha256:d48db7c60b9e81a313180c4022a0d3bf2a2c5c49595e05918c587f2776eaad7c","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:cae6f1a5585e680409dcc6ae53c90ec4e6b471d9bd1e5b7f08a838485cff2e18","anchor":{"event_id":"a3378794aef8d29c74b2cac7863d2f2f326248bdb43974ab3267d4dce410204c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-05T00:15:39.860Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-05T00:15:39.269Z","evidence_url":null,"receipt_uuid":"06106056-2b4d-4ed1-8cee-6a643069452e","output_sha256":"sha256:671f44ad085e4baccf3a7e2506228e1ec64bf549a1636fb6e595b135e3501286","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-05T00:15:39.269Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:671f44ad085e4baccf3a7e2506228e1ec64bf549a1636fb6e595b135e3501286\",\"receipt_uuid\":\"06106056-2b4d-4ed1-8cee-6a643069452e\",\"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":"2026-11-05T00:15:39.269Z","detail":"The receipt store reports 2026-11-05T00:15:39.269Z; 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.
