Zambo is live\n\nHi [Name],\n\nZambo is officially up.\n\nWe built this for one specific problem: finding qualified leads without the usual research grind. You provide a trade and a city. Zambo returns five qualified prospects with contact info in under sixty seconds. It supports twenty-four trades across the US.\n\nYou can test it right now. No API key. No signup. Three free searches per day.\n\nHere is the current status of our tools:\n\n**1. LeadSignal**\nThis is the core lead generation engine. It pulls source-backed prospects for local service businesses.\n*   **Current Status:** Available.\n*   **Limit:** 3 free searches per day per IP.\n*   **Recent Test:** We ran a query for web design in Austin, TX. The system returned zero results. This is a valid outcome. It means there were no matching public source-backed leads for that specific combination at that time. The tool did not error; it simply found no data.\n\n**2. Zambo Universal**\nThis is the entry point for broader tasks. It routes requests across thirty-six tools, including strategy AI, code audits, and market data.\n*   **Current Status:** Available.\n*   **Limit:** 20 total free calls per day across work tools.\n*   **Function:** It acts as a dispatcher. If you ask for an actionable task, it provides a concrete route or executes a live read-only branch if available.\n\n**Why this matters to you**\n\nMost lead tools either hallucinate data or require heavy setup. Zambo prioritizes source-backed accuracy. If it finds nothing, it tells you. That transparency is a feature, not a bug. It saves you time by preventing outreach to non-existent or unverified contacts.\n\nThe platform is free to use within the daily limits. You do not need to commit to a plan to test the value.\n\n**Next Step**\n\nPick a trade and a city you know well. Run a search. Check the results. If the data matches your reality, you have a working tool. If not, tell me why.\n\nYou can start here:\nhttps://zambo.dev/day-pass/\n\nLet me know what you find.\n\nBest,\n\n[Your Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:4ddeac8d7bfa78e708c85540720476883ace4da229959a925f2dc844436b506a","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:bcf10f4b9ad6f169e4e962b8aae809cc10364bbfe6fea4bbc2d7fe6c1cbb3311","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":"sha256:8bf230395856d36cdc536ea875c2c0762fdbaedb5ab082a15b1857fcf1c5c013","anchor":{"event_id":"74cedfea2894856ec2b1abca6e2de1dc7ddf0758a296a0ece43e35dc7279ca4f","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-11-05T04:13:55.013Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-05T04:13:54.340Z","evidence_url":null,"receipt_uuid":"325cd460-a339-435d-bd5a-23d13dc95a59","output_sha256":"sha256:cadec8a50c18140995faa887bc20c1c7b54e184ef8eba3d387522c69d127be4a","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-05T04:13:54.340Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:cadec8a50c18140995faa887bc20c1c7b54e184ef8eba3d387522c69d127be4a\",\"receipt_uuid\":\"325cd460-a339-435d-bd5a-23d13dc95a59\",\"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":"2026-11-05T04:13:54.340Z","detail":"The receipt store reports 2026-11-05T04:13:54.340Z; 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.
