Zambo is live (and it’s fast)\n\nHi [Name],\n\nZambo is officially out of beta.\n\nWe built it to solve one specific problem: finding qualified, source-backed leads for local service businesses without the guesswork. No more scraping random directories or guessing who’s actually ready to buy.\n\nHere’s how it works: You tell us the trade and the city. Within 60 seconds, you get five qualified prospects with verified contact details. It supports 24 trades across any US city.\n\nWe’re launching with a free tier that gives you three searches per day. No credit card. No sign-up friction. Just results.\n\nI tried it on a test run for web designers in Austin. The system returned zero results for that specific query, which is exactly why we built it. It doesn’t invent leads to look good. It only shows you what’s actually there. If a source-backed lead exists, you’ll see it. If not, you’ll know immediately so you can pivot your strategy.\n\nThis tool is designed for contractors, plumbers, electricians, and other local pros who need reliable pipeline growth. It removes the noise and gives you actionable data.\n\nReady to test the waters?\n\nUse this link to run your first search: [Insert Link]\n\nPick a trade you know well. Pick a city. See what comes back.\n\nLet me know if the first run surprises you. I’m watching the metrics closely and want to hear what you think of the data quality.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:6788cf32063b415d2f89de18beb8eeb7570d625d3f56d79800435b2c47eb201c","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":"4.1.0","scope":"public"},"caller":{"type":"session","id":"sha256:45b2ab3c21129434cedb70c3be1ace6d19eb376d06a4d7e9eb3c1b88a53aee31","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:a3f84f6f885c9a1b8fefbf76b3eaed3282028edc7bb57921633358dd885f6511","anchor":{"event_id":"583778a6c4fec3bac05c4309e69253164604faecbbc17d235031b1293a5c907d","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-11T06:32:39.798Z","published_at_semantics":"Relay confirmation time (accepted acknowledgement or exact-event read-back); not the signed event's created_at.","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-11T06:32:38.695Z","evidence_url":null,"receipt_uuid":"df4df394-6ec3-4079-aff5-8d018b5a01d1","output_sha256":"sha256:b82fcff524c92ff4d9c782d07a3e01f70f989745273e1c9e6c8c41b452fe6cc2","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-11T06:32:38.695Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:b82fcff524c92ff4d9c782d07a3e01f70f989745273e1c9e6c8c41b452fe6cc2\",\"receipt_uuid\":\"df4df394-6ec3-4079-aff5-8d018b5a01d1\",\"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":"2026-11-11T06:32:38.695Z","detail":"The receipt store reports 2026-11-11T06:32:38.695Z; 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.
