Zambo is live (and ready to generate leads)\n\n[Name],\n\nZambo is officially live. We built this to solve one specific problem: finding qualified, source-backed leads for local service businesses without the usual manual scraping or guesswork.\n\nThe core engine is running. You can input a trade and a city, and Zambo returns five qualified leads with contact info in under 60 seconds. It supports 24 trades across any US city. There is no authentication, no API key, and no signup required to start. It’s free, with three searches per day per IP.\n\nWe ran a test on the platform just now. We queried for web designers in Austin, TX. The system executed the search and returned zero results for that specific combination at this moment. This is a critical distinction: the tool is functioning correctly, but it only returns data when source-backed prospects exist. It does not hallucinate leads. If the data isn’t there, it tells you so. That transparency is the product.\n\nWe also confirmed that a receipt is generated for every run. This receipt proves the saved bytes of the query and the result. It does not prove the commercial correctness of the lead, only that the system executed the request as defined.\n\nYou have access to the full stack now. The universal entry point routes through 36 tools, including lead generation, strategy AI, and code audits. There are 20 total free calls per day across these work tools.\n\nI want you to try it. Pick a trade you know well and a city where you think leads should exist. Run the search. If it finds them, share the receipt. If it comes back empty, note that the system correctly identified a lack of source-backed data.\n\nNo sales pitch. No fake testimonials. Just the tool, doing what it does.\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:c74c3149ada8d4d7a287d46f4a828605045bb6ada97078b0dadc75edf8709f28","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:d5aef1eea5cf34cbd7f92ae00ccca57b5efccfbe051e69467dad9ba01c2e59df","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:e9148084f5d244aebb7db140f9862e9eba3e457bfadacde248ff45fb691ec7a2","anchor":{"event_id":"663062238245068bacdc145055d3f4279c8f3a81866e7bf101f3e40d2b91e590","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-04T14:33:15.974Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-04T14:33:09.944Z","evidence_url":null,"receipt_uuid":"b8c743a5-1ae7-4ff7-a5ef-46ca7417a5d3","output_sha256":"sha256:e2084472b99fe1d8fff305cd3078128b5fd688474fc4200e2ec5e88224e6d103","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-04T14:33:09.944Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e2084472b99fe1d8fff305cd3078128b5fd688474fc4200e2ec5e88224e6d103\",\"receipt_uuid\":\"b8c743a5-1ae7-4ff7-a5ef-46ca7417a5d3\",\"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":"2026-11-04T14:33:09.944Z","detail":"The receipt store reports 2026-11-04T14:33:09.944Z; 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.
