It solves one specific problem for contractors and local service businesses: finding qualified leads fast.\n\nThe tool, LeadSignal, requires only a trade type and a city. Within 60 seconds, it returns five source-backed prospects with contact information. It supports 24 trades across any US city. There is no authentication required, and the system provides three free searches per day per IP address.\n\nThis is not a database of scraped emails. It is a research engine. The output consists of prospects, not customers. A receipt link proves the saved bytes remain unchanged; it does not guarantee the accuracy of the underlying data.\n\n**How it works:**\n1. Input a trade (e.g., roofer) and a city.\n2. Receive five qualified leads with verified sources.\n3. Review the data before drafting outreach.\n\nThe system does not send messages. It does not invent contacts. It provides the raw material for your team to verify and engage.\n\n**Next Step:**\nTest the workflow yourself. Run a search for a trade and city you know well. Compare the speed and source quality against your current manual process.\n\n[Click here to run your first search]\n\nIf the data meets your standard, we can discuss integrating this into your acquisition pipeline. If it does not, you have spent 60 seconds and gained a benchmark.\n\nRegards,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:069a04df22ef67d6a83ef241fd45a3e61d1b65f56f8113eab7a512aa79f538df","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":"sha256:47f3c19505c022ca82e3c40009814929506885cc970fa6a6ba37a950860e8b16","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":"sha256:12aa47d53168299d5ad79c239ac14cbc9de82a55d0a81e4913f145e16c37d1c4","anchor":{"event_id":"e64cf2ff480d2202f2dfb7a2f6131246c4dba996c273de2932aecad07f60121c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-08T17:09:04.681Z","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":"2026-11-08T17:05:42.068Z","evidence_url":null,"receipt_uuid":"d44c0d4c-fab4-4543-bc04-1ee36e8adf25","output_sha256":"sha256:018c7b6070e458f9b8b25b36eca0fd6820bd062996476006538ca68a3c03cccd","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-08T17:05:42.068Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:018c7b6070e458f9b8b25b36eca0fd6820bd062996476006538ca68a3c03cccd\",\"receipt_uuid\":\"d44c0d4c-fab4-4543-bc04-1ee36e8adf25\",\"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":"2026-11-08T17:05:42.068Z","detail":"The receipt store reports 2026-11-08T17:05:42.068Z; 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.
