Zambo is live (and it found zero leads in Austin)\n\nYou don’t need another AI tool that hallucinates prospects. You need verification.\n\nZambo is officially launched. It connects to real-world data sources to identify potential leads for local service businesses. The system does not guess. It does not invent names. If a source doesn’t back a contact, Zambo reports zero results.\n\nWe ran a test query for web design prospects in Austin, TX. The outcome was clear: no source-backed leads were found. The system returned a status of `no_results` with a count of 0. This is the feature. Accuracy over quantity.\n\nYou can verify this specific run using the receipt ID below. It proves the bytes saved match the query executed. It does not prove the market is empty, only that Zambo’s current sources did not validate a match for that specific trade and location at that moment.\n\n**The Core Promise**\nZambo provides source-backed lead research. It does not send outreach. It does not generate fake contacts. It tells you when the data isn’t there so you don’t waste time on dead ends.\n\n**Your Next Step**\nRun your own test. Pick a trade and a city. Check if the data supports it.\n\n1.  Visit [zambo.dev](https://zambo.dev).\n2.  Enter a trade (e.g., \"roofer\") and a city (e.g., \"Phoenix AZ\").\n3.  Review the source-backed output or the honest \"no results\" flag.\n\nYou get three free searches per day per IP. No auth required. No credit card. Just data integrity.\n\nIf you are building for contractors or local service businesses, stop relying on scraped lists that rot in weeks. Build on verified signals.\n\n**Reference Receipts**\n*   Test Run (Austin/Web Design): [View Receipt](https://zambo.dev/run/b4b34bd7-ce19-422e-b763-837f5814510c)\n*   Product Overview: [zambo.dev](https://zambo.dev)\n\nWe built this for people who value truth in their data pipeline. Try it. Break it. See where the data holds up.\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:ed040197630bf930172f46aab32ebb46c481fb692d2d3e61933182f6979cf882","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:cdd18dd679b5f628bb97ebe529a684f8933985a524b3060e06f0504c954010d3","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:cd80e4f6ebe57e08f47d784576a4d0648048f1296fea30d008a0bdc6fbf3d983","anchor":{"event_id":"d34ad9d8c08fbc8c3f3098740c9b8b43604a22625ad5ecb0e08f4fd4a8ca2fe1","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-11T05:53:49.634Z","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":"2026-11-11T05:52:37.136Z","evidence_url":null,"receipt_uuid":"4de905c6-14c3-4f72-900e-2f5eab186f0d","output_sha256":"sha256:e2413dde4d13f5f4135ece72c34c67be4745eca83179c6506d36aaa23db0bf9f","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-11T05:52:37.136Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e2413dde4d13f5f4135ece72c34c67be4745eca83179c6506d36aaa23db0bf9f\",\"receipt_uuid\":\"4de905c6-14c3-4f72-900e-2f5eab186f0d\",\"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":"2026-11-11T05:52:37.136Z","detail":"The receipt store reports 2026-11-11T05:52:37.136Z; 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.
