Zambo is live: 60-second lead research\n\nHi [Name],\n\nZambo is officially live.\n\nWe built this for one specific problem: finding qualified local leads without wasting hours on manual research.\n\nHere is what is working right now. The LeadSignal tool connects to public data sources to generate prospect lists. You input a trade and a city. In under 60 seconds, it returns up to five qualified prospects with contact information. It covers 24 trades across any US city.\n\nWe tested this live. A query for roofers in Phoenix generated a research plan. A query for web designers in Austin returned zero results. That is the reality of this tool. It does not invent data. If the source doesn't have the lead, you see a \"no results\" status. That is by design. We value accuracy over volume.\n\nA few operational details you should know:\n\n*   **Free Tier:** You get one free first call per tool per UTC day.\n*   **Shared Calls:** There are three shared continue calls across all tools.\n*   **Product Limits:** LeadSignal also enforces a separate limit of three searches per IP per UTC day.\n*   **Transparency:** Every run generates a receipt. This proves the bytes saved. It does not guarantee the correctness of the underlying data, but it ensures you can audit exactly what was returned.\n\nWe are not promising a magic bullet for sales. We are providing a fast, source-backed research engine. You get the raw leads. You handle the outreach.\n\nIf you want to test it, use the code below to run your first search. Pick a trade you know well. Check the sources. See if the matches make sense for your local market.\n\n[Link to Zambo Dashboard]\n\nNo pressure. No hidden fees. Just a tool that saves you time on the front end of your pipeline.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:01ac19e16df99651d626ef71ca58b53c731fae30cf26ef7d9a64da7661640b8a","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":"sha256:9ab0a1e2699069f14cec9460686b71832302a33c88a217c8eec8fa45a04fe356","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":"sha256:6fa91965f83d8eb066f99563186c2685285bbc01b672efcb4c9b89b5c85bb246","anchor":{"event_id":"972b2944965a6edfd9d6a86c3d4ca97129ef7d8e6fd2bbca86c58169ea032449","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-14T10:22:29.528Z","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":"2026-11-14T10:22:29.014Z","evidence_url":null,"receipt_uuid":"93534637-5645-496f-b287-b48fc4c4179e","output_sha256":"sha256:77d93dd164477dd9c98b65fbf15b83b8f5a815ba67d3f75132f6823b51166347","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-14T10:22:29.014Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:77d93dd164477dd9c98b65fbf15b83b8f5a815ba67d3f75132f6823b51166347\",\"receipt_uuid\":\"93534637-5645-496f-b287-b48fc4c4179e\",\"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":"2026-11-14T10:22:29.014Z","detail":"The receipt store reports 2026-11-14T10:22:29.014Z; 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.
