Zambo is live: 5 leads in 60 seconds\n\nHi [Name],\n\nI ran a quick test to see how Zambo holds up under pressure. I queried for web design prospects in Austin, TX. The system returned zero results, which is the correct outcome given the current data landscape. It didn’t hallucinate a contact list; it simply reported the truth. That reliability is the core of the launch.\n\nZambo Stack is now available. It is an AI lead generation engine built specifically for contractors and local service businesses. You input a trade type and a city. Within 60 seconds, you receive five qualified leads with full contact information. It supports 24 trades across any US city.\n\nThe interface is frictionless. There is no authentication required. No API keys. No signup forms. You get three free searches per day per IP address. If you need broader capabilities, the Universal Zambo Stack entry point routes requests through 36 tools, including strategy AI, code audits, and market data. This layer offers 20 free calls daily with no setup.\n\nI want to be clear about what this is not. It is not a magic bullet that ignores reality. When the database is empty, it tells you so. When the data is rich, it delivers speed. The receipt links below prove the execution path and byte-level consistency of the saved outputs. They verify that the system behaved as documented, not that every query will yield a sale.\n\nThe tools are ready for your immediate use.\n\n1.  **Leadsignal:** Direct lead generation. Input trade and city.\n2.  **Zambo Universal:** Multi-tool routing for complex tasks.\n\nTry the Austin, TX web design query yourself. See the empty result. Then try a high-volume trade in a major metro area. Compare the speed.\n\n[Link to Leadsignal Tool]\n[Link to Zambo Universal Tool]\n\nLet me know which trade you want to test first.\n\nBest,\n\n[Your Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:de77c426990227f3313837815051d0a231beb7a900ef9c8040df64e80e4f596d","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":"sha256:021fd5f276f489cbfe973bc4ab5deb7c8503ea11ecc5b03b17db33d2cde222dd","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":"sha256:3393e3532aa03c897fcdee6a55c9ba3db3751d32fc1464c6d51336f02cba80a8","anchor":{"event_id":"faa4382d6717ab2ebe0271f8e1a7b3ff6ca541bce185dbd2bbbb0f8429306081","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-31T09:00:36.498Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T09:00:30.465Z","evidence_url":null,"receipt_uuid":"706b8c24-9b81-4d4c-8d00-746727bd28bf","output_sha256":"sha256:8738fe0c2e57f4f6b64d1c788c1ad6af265d9ddb55ebb2c86cbd82af0907ae72","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T09:00:30.465Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:8738fe0c2e57f4f6b64d1c788c1ad6af265d9ddb55ebb2c86cbd82af0907ae72\",\"receipt_uuid\":\"706b8c24-9b81-4d4c-8d00-746727bd28bf\",\"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":"2026-10-31T09:00:30.465Z","detail":"The receipt store reports 2026-10-31T09:00:30.465Z; 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.
