You pick a trade and a city. We return five qualified prospects with contact info in under 60 seconds.\n\nIt supports 24 trades across the US. No signup. No API key. No auth. Just three free searches per day per IP.\n\nWe tested the engine in Austin, TX, for web design. The system returned zero source-backed leads at that moment. That is the correct behavior. We do not hallucinate data to make a demo look good. If the source doesn't have it, we tell you it doesn't have it. A receipt proves the bytes saved, not the correctness of the lead, but the transparency is the point.\n\nWe are not sending these to anyone yet. This is a quiet launch.\n\nTry it yourself. Go to [Link to Zambo Stack] and run a search for a trade you know in your city. See if it returns real, verifiable contacts. If it does, you have a tool that saves you hours of manual digging. If it doesn’t, you know exactly why.\n\nNo pitch. No webinar. Just a tool that works or doesn’t.\n\nLet me know what you find.\n\n[Your Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:cb71cb7ef8a5626e04a3679d8275f29c98495e5aca8e1ddbbf003096a33f534f","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":"sha256:4a718badea24293690911f22f10e9634cc2b73ba42f18bf446b03f21bb7ed5c2","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":"sha256:3e03da82ce63bdb6009211bf728522048ebd67533c36c4d4e675e5eea45c7a63","anchor":{"event_id":"a80abb5fdee849394839b82875a3ca9d6353a3f1da5dae1a0cc8fcbea4e09f6c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-04T06:33:10.615Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-04T06:33:09.896Z","evidence_url":null,"receipt_uuid":"b1b6a8a9-1f91-4b40-9e0c-e3967ee4f926","output_sha256":"sha256:4b9f9d87f65c25bfd72c5f0d02343f2a37a84af3e894285833dc82c7118a7246","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-04T06:33:09.896Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:4b9f9d87f65c25bfd72c5f0d02343f2a37a84af3e894285833dc82c7118a7246\",\"receipt_uuid\":\"b1b6a8a9-1f91-4b40-9e0c-e3967ee4f926\",\"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":"2026-11-04T06:33:09.896Z","detail":"The receipt store reports 2026-11-04T06:33:09.896Z; 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.
