Zambo Launch: Your First Lead Search\n\nHi [Name],\n\nThe Zambo launch is live. We built this for one specific problem: finding qualified, source-backed prospects for local service businesses without wasting hours on unverified lists.\n\nHere is what you can do right now. Zambo Stack connects to 36 tools via a single interface. The core feature for this launch is `leadsignal`. You provide a trade and a city. In under 60 seconds, you receive five qualified leads with contact information. It supports 24 trades across any US city. There is no signup, no API key, and no cost. You get three free searches per day per IP address.\n\nI just tested the system with \"web design\" in Austin, TX. The search returned zero results. This is a critical distinction. A receipt proves the system processed the request and saved the bytes; it does not prove the data is correct or that leads exist. If the database is empty for that specific query, the tool says so. It does not hallucinate prospects. It does not fabricate names. It returns only source-backed data. If there are no leads, you get a clear \"no results\" status. This transparency protects your time. You spend your three daily searches only on queries that have actual potential.\n\nThe broader Zambo Universal tool routes requests to strategy AI, code audits, wallet intelligence, and market data. All of this is free, with no API key required. The limit is 20 total free calls per day across work tools.\n\nWe are not sending this as a pitch. We are sharing the live tool. If you have a specific trade and city in mind, run the check. The response is instant. If it finds leads, you have your next step. If it doesn't, you saved an hour of manual digging.\n\nHere is the direct link to run your first search: [Insert Link to Zambo LeadSignal]\n\nReview the output. Verify the source backing. If it matches your criteria, proceed. If not, adjust the parameters.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:03a221e9cba338cf3ae3681c4a748f42ad349e6d1cf082200d6c0019133fca0d","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:a4004db84527c64290a454d1889eaf05a925a0241a6d6a4cb6e4fa1a907570f9","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":"sha256:0046d63aeaafda64ca9d56408f6c48ecee036bb8e5e433373ab0143fadcca69a","anchor":{"event_id":"ece6422cc981cd48c13481c48ad872ea82886b03e40c659dd27b763a6fb2fb12","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-05T02:25:30.742Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-05T02:25:30.139Z","evidence_url":null,"receipt_uuid":"28a021cc-2a84-4800-a5e9-3dfe203c3f37","output_sha256":"sha256:679eeecd71ad857eb74d3da9e5965dc1c02216c0d675f17f2a20a3ed92d6b0d4","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-05T02:25:30.139Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:679eeecd71ad857eb74d3da9e5965dc1c02216c0d675f17f2a20a3ed92d6b0d4\",\"receipt_uuid\":\"28a021cc-2a84-4800-a5e9-3dfe203c3f37\",\"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":"2026-11-05T02:25:30.139Z","detail":"The receipt store reports 2026-11-05T02:25:30.139Z; 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.
