Zambo is live: Source-backed lead research\n\nHi there,\n\nZambo is officially up.\n\nWe built this for one specific problem: finding qualified, source-backed leads without burning hours on manual research.\n\nRight now, you can use LeadSignal to pull five qualified prospects for any trade in any US city in under 60 seconds. The system scans public sources to verify details, ensuring every contact is real and relevant. No guessing. No scraped junk lists.\n\n**What you get:**\n*   **24 Trades Supported:** From roofers to web designers.\n*   **Instant Verification:** Source-backed data, not invented contacts.\n*   **Free Tier:** 3 searches per day per IP. No auth required.\n\nWe’ve run initial tests in markets like Austin, TX and Phoenix, AZ. The tool returns strictly verified prospects; if a source isn’t available, it tells you, rather than fabricating a lead. That distinction matters when you’re building a pipeline.\n\n**Next Step:**\nTest the accuracy yourself. Pick your trade and city. Run a search. Check the sources.\n\n[Start Free Search]\n\nThis is a research tool. It drafts messages and verifies contacts. It does not send outreach. You remain in control of the conversation.\n\nWe are refining the semantic analysis engine to catch edge cases faster. The core loop works: Input trade/city → Get verified leads → Draft outreach.\n\nIf the data matches your reality, we want to hear about it. If it misses the mark, tell us where.\n\nZambo\n\n[Link: View Today’s Research]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:62fba20d4fb503579d21fc6d91fd28c108d1a0bdfce6ef6fab320662760af4f1","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:ffa755411e9c9a28d388e57e7c41ecccb916c253cf59d3bf6c08ee3f3aa7dede","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:be26599859461099b2a88b8feca18581c95897db393d083b0e6f504f2f675c0c","anchor":{"event_id":"76d9eeed0f698fa8f821b6a461396cb2f45c0d025a846fd30a0c8ee86420351b","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-12T13:03:06.612Z","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":"2026-11-12T13:03:05.946Z","evidence_url":null,"receipt_uuid":"24d2c580-ade2-46da-822f-3a553b01e1ca","output_sha256":"sha256:4bd304edacbbd16d6605817e53145a4e364a6e2346f3b0197f1579713a0f0fe9","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-12T13:03:05.946Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:4bd304edacbbd16d6605817e53145a4e364a6e2346f3b0197f1579713a0f0fe9\",\"receipt_uuid\":\"24d2c580-ade2-46da-822f-3a553b01e1ca\",\"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":"2026-11-12T13:03:05.946Z","detail":"The receipt store reports 2026-11-12T13:03:05.946Z; 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.
