Zambo is live**\n\nHi [Name],\n\nSkipping the small talk: Zambo is officially out of beta.\n\nWe built Zambo for one specific problem: local service businesses losing money because they can’t find qualified leads fast enough. No more cold-calling lists that are three years old. No more guessing which trade needs attention in your city right now.\n\nZambo gives you five qualified, source-backed leads for any of 24 trades in under 60 seconds. You pick the trade and the city; we handle the rest. It’s free to test, with no signup and no API key required.\n\nI tried it this morning. I searched for web designers in Austin. The system returned zero results for that specific query. That’s the point. It doesn’t hallucinate prospects to make you feel good. It only pulls data that exists. If there are no source-backed leads in that niche right now, you’ll know immediately. That clarity is worth more than a fake list.\n\nYou can see exactly how the engine works and verify the output via this public receipt:\n\nhttps://zambo.dev/run/1f51fea9-d684-4306-b0cc-c0cd2c5e1787\n\nThis link proves the bytes saved. It doesn’t prove correctness, but it does prove transparency. You can audit the exact request and response.\n\nHere’s what you can do with this:\n\n1.  Copy the link into your browser.\n2.  Look at the input parameters (Austin, Web Design).\n3.  Notice the \"no_results\" status.\n4.  Trust that the tool tells you the truth, even when the truth is \"zero.\"\n\nIf you manage a local service business, or if you advise them, this tool removes the friction of discovery. You get instant data, not promises.\n\nWant to see what’s available for your specific trade and city? Drop your trade and city in a reply. I’ll run the search and send you the receipt. No sales pitch. Just data.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:cd73ceb869ed825ccc6b52814e59647cc70c69327f1eddf6235c8aaa576f6142","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":"sha256:1fa8747f0a209e40156dde9473842faaf32372eb04f30e1dc4fb085962a04643","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":"sha256:6bb244f7c37ab7b6bf88b580d10b8b28b2c0b87341c0cc2a78174a145e763348","anchor":{"event_id":"33135ccd6f065ac77110fdecf960cf5a4dd40b1bae8296e05192b81c56185721","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-02T20:53:15.248Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-02T20:53:09.199Z","evidence_url":null,"receipt_uuid":"bb3b2bd1-e772-4ebb-911b-5a49b37ad9ad","output_sha256":"sha256:2ef0ccaf8893a36d7aeb301d027b9fce3b6f5a7207d4786d95706bcffc2f7786","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-02T20:53:09.199Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:2ef0ccaf8893a36d7aeb301d027b9fce3b6f5a7207d4786d95706bcffc2f7786\",\"receipt_uuid\":\"bb3b2bd1-e772-4ebb-911b-5a49b37ad9ad\",\"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":"2026-11-02T20:53:09.199Z","detail":"The receipt store reports 2026-11-02T20:53:09.199Z; 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.
