Zambo is live: 60-second lead generation for local trades\n\nHi [Name],\n\nZambo is officially out of beta and ready for your first live run.\n\nWe built this specifically to solve the \"where do I find qualified prospects\" bottleneck for contractors and local service businesses. You input a trade and a city. In under 60 seconds, you get five qualified leads with direct contact info. No guesswork. No cold-calling dead numbers.\n\nThe platform supports 24 trades across any US city. You get three free searches per day, per IP, with no authentication or signup required. It is designed to plug directly into your existing workflow, not replace it.\n\nI tested the system today using Austin, TX, and \"web design\" as parameters. The tool returned zero source-backed leads for that specific query. I am sharing the receipt below not as a failure, but as proof of integrity. A receipt verifies the exact bytes saved by the system. It proves the tool executed the search and returned the data exactly as it exists in the source. It does not fabricate names to make the demo look good. If the data isn’t there, you see \"no results.\" That transparency is the core of Zambo.\n\nYou can verify the integrity of that specific run here:\nhttps://zambo.dev/run/8d9f7da9-688b-41f8-b6d9-e2c1babf1c50\n\nFor broader access, the Zambo Universal Stack offers 20 free daily calls across our 36-tool suite, including strategy AI and market data. No API keys. No subscriptions for the free tier.\n\nYour next step is simple. Pick a trade and city where you know leads exist. Run the search. Check the receipt.\n\nIf the data matches your reality, we are ready to scale. If it doesn’t, tell me where the gap is.\n\n[Your Name]\n[Your Title]\n[Your Contact Information]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b3b0651a6074a3de765036c3c45755993577f7521e2f2a648ffcc7a3a741d701","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":"sha256:46c4a0e7cac3c26d32edf6ee57212c20d68a6bb65fe22f8096a5948e9b56b454","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":"sha256:473a22ef8ae70b36939cb80ef8726c8e1aaf8b0ca3c87317973bdd8eb0706fc6","anchor":{"event_id":"5ec17d46f988ff2a3abadebe4b480b142e609e40c42e503466cb737daaf32b1c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-02T23:13:06.430Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-02T23:13:05.800Z","evidence_url":null,"receipt_uuid":"b371e071-1055-4525-90f7-7652788e4aa4","output_sha256":"sha256:69f7e5d3c91aaabfd67f64b75a58282db40a06dba159ca5f35c3550de04bed65","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-02T23:13:05.800Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:69f7e5d3c91aaabfd67f64b75a58282db40a06dba159ca5f35c3550de04bed65\",\"receipt_uuid\":\"b371e071-1055-4525-90f7-7652788e4aa4\",\"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":"2026-11-02T23:13:05.800Z","detail":"The receipt store reports 2026-11-02T23:13:05.800Z; 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.
