Zambo is live (and it’s faster than expected)\n\nYou’re here because you want to know if this tool actually works, not to read a marketing fluff piece.\n\nZambo is officially launched. It solves one specific problem: finding qualified, source-backed leads for local service businesses in under 60 seconds.\n\nHere is the current state of the product:\n\n1. **The Core Functionality Works:** The system successfully routes queries for 24 different trades across any US city.\n2. **The Output is Honest:** If the data isn’t there, the tool says so. In our latest test for web designers in Austin, TX, the system returned zero results. It did not hallucinate a customer. It did not invent a name. It simply reported that no source-backed leads were available at that moment. That transparency is the product.\n3. **Access is Open:** No API key. No signup friction. Currently, you get 3 free searches per day per IP.\n\nThis is not a beta with hidden bugs. It is a tool that prioritizes accuracy over volume. When it returns a lead, it is a prospect backed by source data, not a guess. When it returns nothing, it saves you the time of chasing a ghost.\n\n**Your next step:**\n\nTest it yourself. Go to the dashboard, pick a trade you know well, and pick a city. You will see the logic in action immediately.\n\n[Link: Start Your First Search]\n\nWe are building for contractors and local service owners who are tired of scraping leads that don’t convert. If you have feedback on the interface or the speed, I want to hear it. But I want to hear it after you’ve run your first query.\n\nThe receipt link below proves the system ran. It does not prove the data is perfect, because the data is whatever the source says it is. Our job is to fetch it fast and format it clearly.\n\nLet’s skip the hand-holding. Run the search. Tell me if it saves you time.\n\nBest,\n\n[Your Name]\nFounder, Zambo\n[Link: View Run Receipt]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:4bbdfb68f98e0abebb6ec8e16310f18e10762bea8d431c2189331cf6ee0b8c8f","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":"sha256:3666d4b169bed4772da4d8134ce898b08e093ef4c4e39c11c461e9745702efa4","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:da502a8243b2ef4064c34a6bacf8646c257a83ae064b42beec1f8a36e68656cf","anchor":{"event_id":"35fbcb751b56d5ea809e8bb40b5a4fa8854d7f2686ef1d332b78c05be3c8bc85","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-01T07:21:30.881Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-01T07:21:27.957Z","evidence_url":null,"receipt_uuid":"d67ca57a-f6c9-4bf9-a8c9-f96a1e6539e3","output_sha256":"sha256:4d2f4a1a8a6744f7e0dbb9718603189b14bc49801528b5de4df7aeb4503df7af","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-01T07:21:27.957Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:4d2f4a1a8a6744f7e0dbb9718603189b14bc49801528b5de4df7aeb4503df7af\",\"receipt_uuid\":\"d67ca57a-f6c9-4bf9-a8c9-f96a1e6539e3\",\"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":"2026-11-01T07:21:27.957Z","detail":"The receipt store reports 2026-11-01T07:21:27.957Z; 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.
