Zambo is live: 60-second lead research for local trades\n\nYou’re likely tired of manual lead gen. Zambo changes that.\n\nZambo Stack is now operational. It identifies source-backed prospects for contractors and local service businesses in under 60 seconds. No guessing. No cold emails to the wrong person. Just verified data.\n\nHere is what we observed in the latest test run:\n\n1.  **Execution Plan:** We queried LeadSignal for web designers in Austin, TX.\n2.  **Result:** Zero source-backed leads were returned.\n3.  **Status:** The tool executed correctly. It returned a clear \"no_results\" status with a specific receipt ID.\n\nThis is a critical distinction. A receipt proves the system ran and saved the bytes. It does not prove market viability. If the tool finds no one, it tells you so. It does not hallucinate names or invent customers to please you. It respects the data.\n\nZambo supports 24 trades across any US city. It uses MCP access with free daily limits for initial testing. You get qualified leads with contact info, or you get a clear signal to try a different trade or city. There is no ambiguity.\n\nWe are not sending outreach. We are not inventing findings. We are providing a research engine that works when the data exists and reports honestly when it doesn’t.\n\n**Next Step:**\n\nRun your own test. Pick a trade you know well and a city where you have presence. Call `leadsignal` with those parameters. Check the receipt. See if the data holds up.\n\nIf it works, you have a pipeline. If it fails, you have saved yourself hours of dead-end prospecting.\n\nThe tool is live. The receipts are public. The judgment is yours.\n\nRun the test.\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:156f425f9711b7fba6a2e878bd75e6e58f09e7fd67ddeaaba0b671a6f3741211","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":"4.1.0","scope":"public"},"caller":{"type":"session","id":"sha256:a359b4b5ea8f50f797069ff5ba8a04760aace0d7bbab62db5ec4e5ebcd7375fa","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":"sha256:140cec6a995be2110b20c57603b7082460396aea0a0417d43733643dd3166cb2","anchor":{"event_id":"3303efde4af7f7766a82a36ef0efe99cf2ba855952eabb0fb3627ef9addc31e8","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-13T18:07:39.374Z","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":"2026-11-13T18:07:38.721Z","evidence_url":null,"receipt_uuid":"a77f8be6-6732-4e10-8ec9-b90eb0d396a8","output_sha256":"sha256:96cacf285ca05d2f12e201ea059040d3ac997dc6e6e445caf9950e9edd37918f","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-13T18:07:38.721Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:96cacf285ca05d2f12e201ea059040d3ac997dc6e6e445caf9950e9edd37918f\",\"receipt_uuid\":\"a77f8be6-6732-4e10-8ec9-b90eb0d396a8\",\"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":"2026-11-13T18:07:38.721Z","detail":"The receipt store reports 2026-11-13T18:07:38.721Z; 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.
