Zambo changes that.\n\nZambo Stack is now available to contractors and local service businesses. The core function is simple: provide a trade type and city, and receive five source-backed qualified leads with contact information in under 60 seconds.\n\nThis isn’t a generic list. The system verifies data sources before returning results. If the data isn’t there, you get a clear “no results” message, not filler. It supports 24 trades across any US city.\n\nWe recently tested the system with a query for web designers in Austin, TX. The result was zero leads. That’s the point. We don’t invent prospects. A receipt proves the saved bytes of the query, not the correctness of the data. If we found a roofer in Phoenix, those would be labeled as prospects, not customers, until you make contact.\n\nThe free tier includes one first call per tool per UTC day, plus three shared continue calls. No auth required.\n\n**Next Step:**\nRun your first query today. Pick a trade and city you know well. Check if the leads hold up against your own knowledge.\n\nIf the data is accurate, you have a new lead source. If it’s empty, you’ve saved time you would have wasted on dead ends.\n\n[Start Free Trial]\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:dd8a5546d0c74539c77f6e59682cda69b39aa8dcffe533e8737a9c353f511c11","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":"4.1.4","scope":"public"},"caller":{"type":"session","id":"sha256:457cbf63ae46bb6854e2a4e591d356e68eae9e2d36fa464b01d12acc3ce3f2b2","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":"sha256:734b74c43b3c23c233682f11ac48b9d29f8bfaf38df66484e9e02c0f8715e7b4","anchor":{"event_id":"de0ccf16dd2f2b29bb960d21ba748c4d2ef1b1e989fe64f2508ff8d7669c0e52","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-15T07:36:20.974Z","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":"2026-11-15T07:36:20.445Z","evidence_url":null,"receipt_uuid":"2c4c2d5f-5671-432b-856e-7d8b4c655b8b","output_sha256":"sha256:73a2aa09ad4aa757b9b895869c166d3d4e263fd232610819ab249bbbcbc4070c","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-15T07:36:20.445Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:73a2aa09ad4aa757b9b895869c166d3d4e263fd232610819ab249bbbcbc4070c\",\"receipt_uuid\":\"2c4c2d5f-5671-432b-856e-7d8b4c655b8b\",\"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":"2026-11-15T07:36:20.445Z","detail":"The receipt store reports 2026-11-15T07:36:20.445Z; 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.
