It supports 24 trades across any US city. You get five qualified leads with contact info in under 60 seconds.\n\nWe tested it today in Austin, TX for web design. The system returned zero results. That is the correct behavior. We do not invent prospects. If the data isn’t there, we don’t fake it.\n\nThe receipt URL below proves the query ran and returned empty. It does not prove the tool is broken. It proves the tool is honest.\n\nThis is the core difference. Most AI lead tools hallucinate names to look impressive. Zambo returns what exists. If there’s no source-backed lead, you get a clear “no results” message and a receipt.\n\nYou can verify this yourself. Three free searches per day per IP. No signup. No API key.\n\n[Link to Zambo](https://zambo.dev)\n\nIf you want to test it for your trade, pick a city and a trade type. If you get results, you have leads. If you don’t, you have a receipt proving why.\n\nNo risk. No fluff. Just the data that’s actually there.\n\nLet me know what you find.\n\nBest,\n\n[Your Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:9c5721d7a5c47a849d9cc409d6ed2ef64fc4e739f15b9a2ace17f75ffe5509e0","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":"sha256:16506ebe6678bd164332c3a9aa953c5ad25f59612c35683b36f99cacff2c6eb7","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":"sha256:8e2e203aa8bbf2e698c027bc0ae7a3f50d1516177b1518dbe725aff4a49b5e90","anchor":{"event_id":"02cb28a6ca306c5734c0f0c740bf4d8f8a90b60842b1a8268791e80feeaf48a8","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-31T11:00:31.964Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T11:00:31.212Z","evidence_url":null,"receipt_uuid":"1cfc01ba-60e1-4b4f-a181-cf3eb8770a82","output_sha256":"sha256:272a18127d40bdd9559b446d10c2736cd635d52d7cc85f925d8e718784f5fefd","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T11:00:31.212Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:272a18127d40bdd9559b446d10c2736cd635d52d7cc85f925d8e718784f5fefd\",\"receipt_uuid\":\"1cfc01ba-60e1-4b4f-a181-cf3eb8770a82\",\"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":"2026-10-31T11:00:31.212Z","detail":"The receipt store reports 2026-10-31T11:00:31.212Z; 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.
