We built it to solve one specific problem: finding qualified, source-backed leads for local service businesses without the guesswork of cold outreach.\n\nThe tool works simply. You provide a trade type and a city. In under 60 seconds, Zambo returns five qualified leads with contact information. It supports 24 trades across any US city. There is no signup, no API key, and no auth required. You get three free searches per day, per IP address.\n\nWe ran a live test today to verify the system. We queried for web design prospects in Austin, TX. The result was zero leads. This is the intended behavior. Zambo does not invent data. It only returns source-backed prospects. If the data doesn’t exist, it tells you so. That honesty is the core of the product. A receipt confirms the query ran and the saved bytes are unchanged, but it is the source validation that matters. You get real prospects, not hallucinated names or fake numbers.\n\nWe are not asking you to buy anything right now. We are asking you to test it.\n\n**Try it here:** [Insert Link to Zambo Lead Signal]\n\nPick a trade you know well. Pick a nearby city. Run the search. See if the leads hold up against your own local knowledge. If they do, you have a tool that saves hours of manual research every week. If they don’t, let us know why. We want the system to work, not just to look good.\n\nThe first three searches are free. No credit card. No pressure. Just data.\n\nLet me know what you find.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:270aeb7de4627a9633b08c8d36dfea453cd2e9bbb891d319013bc0dfbe5e507c","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":"sha256:1dd6b56386db30aa76697d0b718b63405f808f86ff4a0fc4130db2ba95ab119c","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":"sha256:10a9e6d8067bf947b6978c715c03a3aefdb46a3163b8a0f619027e93a91b5aa2","anchor":{"event_id":"ef6b0e89a4627147774dd3cc16e814edab3eb15045e3a7e05e74b84dc47c7482","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-31T16:30:37.238Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T16:30:31.203Z","evidence_url":null,"receipt_uuid":"471c288c-d5d7-4481-b56f-31db17a3152c","output_sha256":"sha256:1ab5fff966c038d7869e73d9fcac08b0b40bd5a57b0f135d695f3676b1d75bb3","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T16:30:31.203Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:1ab5fff966c038d7869e73d9fcac08b0b40bd5a57b0f135d695f3676b1d75bb3\",\"receipt_uuid\":\"471c288c-d5d7-4481-b56f-31db17a3152c\",\"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":"2026-10-31T16:30:31.203Z","detail":"The receipt store reports 2026-10-31T16:30:31.203Z; 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.
