Zambo is live: instant lead research for local businesses\n\nWe are launching Zambo Stack, a tool designed to find source-backed prospective customers for AI tools and local service businesses.\n\nZambo’s primary function is rapid lead generation. You input a trade type and a city; the system returns up to five qualified leads with contact information in under 60 seconds. It supports 24 trades across any US city.\n\nThe platform operates on a free tier. You get three free searches per day per IP address. No authentication, API key, or signup is required. This allows for immediate testing without administrative overhead.\n\nA critical distinction exists in how we handle data. A run receipt proves that specific bytes were saved and unchanged. It does not prove the data is correct. Furthermore, findings are described strictly as prospects. We do not label them as customers until a relationship is established. We do not invent sales, names, or completed fixes.\n\nCurrent testing shows that results vary by location and demand. For example, a recent query for web design in Austin, TX, returned zero results. This is a valid outcome indicating low current inventory for that specific niche in that city. The system remains operational and ready for the next query.\n\nZambo also offers a universal entry point via MCP. This routes requests through 36 tools, including strategy AI, code audits, and wallet intelligence. It provides 20 free calls per day across work tools. This is useful for teams needing multi-functional research capabilities without managing multiple subscriptions.\n\nTo test the system, use the lead signal tool with a specific trade and city. Verify the receipt URL to confirm the execution. If results are empty, try a different trade or city. The goal is to validate the speed and utility of the search, not to guarantee immediate hits in every location.\n\nStart with a high-volume trade in a dense urban area to see the full capability. Review the output format and speed. If the data meets your research standards, integrate the tool into your workflow. If not, adjust your parameters.\n\nThe product is live and accessible. No gatekeeping. Just input and output.\n\nBest,\n\nZambo Team\nhttps://zambo.dev","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:4db04fbadba9806c2baf38fe3ac68374297d52effad9656dfc1f2332bcd36b26","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:f163530966e6cf9f0824d0a55424d5b614fd8c4727612472d174318b94cf3506","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:d5321424ff31998b770eff926f05c0a2b4a761223d7bfca80ad5cd129057c478","anchor":{"event_id":"2e2a67e9367013a1195ecd16ada4eab3c491628dce213dfcf13acc9228982831","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-03T19:48:29.899Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-03T19:48:29.265Z","evidence_url":null,"receipt_uuid":"a7ec32b2-0f50-45fb-9a59-a0822c2ea832","output_sha256":"sha256:749bd1f0ad466c7ce269cdd61b65d3f7f2c43f627ebd96054eef768c81df2006","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-03T19:48:29.265Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:749bd1f0ad466c7ce269cdd61b65d3f7f2c43f627ebd96054eef768c81df2006\",\"receipt_uuid\":\"a7ec32b2-0f50-45fb-9a59-a0822c2ea832\",\"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":"2026-11-03T19:48:29.265Z","detail":"The receipt store reports 2026-11-03T19:48:29.265Z; 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.
