Zambo just launched, and I want to show you exactly what it does, what it doesn’t, and how you can use it for free right now.\n\nHere is the single most important thing you need to know: **Zambo provides source-backed prospects, not guaranteed sales.**\n\nIf you search for leads, the tool gives you qualified names and contact info. A \"receipt\" from the system proves we returned data; it does not prove that person will buy your service. We treat these as prospects, not customers. If you expect a magic button that fills your pipeline, you will be disappointed. If you want a fast, transparent way to find real people in specific trades, we are a strong fit.\n\n**The Proof**\n\nI ran a live test today.\n*   **Request:** Web design leads in Austin, TX.\n*   **Result:** Zero source-backed leads found at this moment.\n*   **Transparency:** The system reported \"no results\" rather than hallucinating a list.\n\nThat honesty is the product. We don’t invent findings. We don’t fake success. We give you the data that exists, instantly.\n\n**Your Move**\n\nYou have 20 free calls on the Zambo Stack today. No API key. No signup. No credit card.\n\n1.  Visit: https://zambo.dev\n2.  Try `leadsignal` with a trade and city where you have actual business.\n3.  Check the receipt. See if the source-backed data matches your ground truth.\n\nIf it works for you, great. If it doesn’t, you lost two minutes, not your money.\n\nI’m building this in public because I believe transparency beats hype. Let me know if the data holds up for your specific trade.\n\nBest,\n\n[Your Name]\nFounder, Zambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:66c6940c2918989654ea896702b100344d9bfc4e387d0507e14c73f7a20268b5","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":"sha256:90f65091386a00858c620fb6fdca56fa037e3363ae29638ad2cc096530d690ba","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:aaa3b4b3bfad9d8684f88d0a7354b1bd681e7433cb2c30301d27fe763e96fec2","anchor":{"event_id":"1437229b1714ec735c402dce7b1fd72209ac670a85a14db738a0eaab3f3cb8e4","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-31T01:20:46.524Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T01:20:45.976Z","evidence_url":null,"receipt_uuid":"6db82eeb-2949-4779-b288-bb6975d3b2b3","output_sha256":"sha256:8e1f4dda668b3fd9f231043c8d060645d48db482609c7492f5a07a9050628aa2","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T01:20:45.976Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:8e1f4dda668b3fd9f231043c8d060645d48db482609c7492f5a07a9050628aa2\",\"receipt_uuid\":\"6db82eeb-2949-4779-b288-bb6975d3b2b3\",\"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":"2026-10-31T01:20:45.976Z","detail":"The receipt store reports 2026-10-31T01:20:45.976Z; 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.
