Zambo is live: 60-second lead research\n\nYou’re reading this because you build for local service businesses.\n\nZambo Stack is now in public launch. It solves one specific pain point: finding qualified, source-backed leads for contractors in under 60 seconds.\n\nHere is exactly what the tool does right now:\n*   **Input:** Trade type and US city.\n*   **Output:** Up to 5 qualified leads with contact info.\n*   **Speed:** Under 60 seconds.\n*   **Scope:** 24 trades, any US city.\n\nWe are not promising sales. We are promising verified research. The system returns source-backed prospects, not guesses. It does not send outreach. It does not automate emails. It gives you the data to make the call yourself.\n\n**Current Status & Constraints**\nThe tool is functional but currently operating under free tier limits.\n*   **Quota:** 3 searches per IP per UTC day.\n*   **Access:** No authentication required for initial testing.\n*   **Verification:** Every run generates a unique receipt URL proving the data was retrieved from public sources.\n\n**Why this matters**\nMost lead generation tools sell you \"potential\" customers. Zambo sells you verified data points. If the data isn’t there, the tool says so (e.g., recent tests for \"web design\" in Austin returned zero results). We prioritize accuracy over volume.\n\n**Call to Action**\nTest the engine yourself.\n1.  Go to [Zambo Launch Page Link]\n2.  Input a trade (e.g., \"Roofer\") and a city (e.g., \"Phoenix, AZ\").\n3.  Check the receipt for source verification.\n\nWe are not asking for your email yet. We are asking you to verify the speed and the source links. If the data holds up, we will follow up with beta access details. If it doesn’t, tell us what’s missing.\n\nThe product is ready for your scrutiny.\n\nBest,\n\n[Your Name]\nFounder, Zambo Stack","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:04eb46cd2850b875831fe9b34aa9deba293a8dfbe7ec57c4df1defd0052cca5e","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:c0c72d9e03886d0e0821d61b8743f83abc8f2478a5cdea49e4cb9f7705059017","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":"sha256:97ba7c88525eb60a0f63a62e3850a7eae5785daa5b26fe7aeecbcaf502dff596","anchor":{"event_id":"f000c91ffee69f06d7ce18e14831e8923c0c5c82c620e056963f1b116f38e430","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-14T10:02:31.401Z","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":"2026-11-14T10:02:28.873Z","evidence_url":null,"receipt_uuid":"5f8c58f5-056d-4fda-8d6e-d1ee7b9d5730","output_sha256":"sha256:8c8adabfbc80a476a808e1ad503967e333d610e67a47e96c3925a1bf810de906","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-14T10:02:28.873Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:8c8adabfbc80a476a808e1ad503967e333d610e67a47e96c3925a1bf810de906\",\"receipt_uuid\":\"5f8c58f5-056d-4fda-8d6e-d1ee7b9d5730\",\"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":"2026-11-14T10:02:28.873Z","detail":"The receipt store reports 2026-11-14T10:02:28.873Z; 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.
