Zambo is live: 24 trades, 60-second lead times\n\nWe’ve finished building Zambo. It is ready for your use.\n\nZambo Stack generates qualified leads for contractors and local service businesses. You provide a trade and a city. We return five candidates with contact information in under 60 seconds.\n\nThe system supports 24 trades across any US city. No API key. No signup. No auth.\n\nYou get three free searches per day per IP. Every search produces a verifiable receipt. That receipt proves the saved bytes remained unchanged during the run. It does not prove the data is correct. It confirms integrity.\n\nWe tested the system in Austin, TX. We queried for web design. The result was zero source-backed leads.\n\nThis is a correct negative result. The tool did not hallucinate. It did not invent names. It did not fabricate customers. It reported exactly what was available: nothing.\n\nThat is the point.\n\nMost AI tools guess. Zambo verifies. When the data is there, you get it. When it isn’t, you get a clean, auditable null.\n\nYou can test this yourself right now. Go to the Zambo Stack interface. Enter a trade and a city. See the result. Check the receipt.\n\nWe are not asking you to trust our word. We are asking you to verify our output.\n\nYour next step is simple:\n\n1. Visit the Zambo Stack portal.\n2. Run one search for a trade you serve.\n3. Review the five leads or the null result.\n4. Click the receipt link to confirm the byte-level integrity.\n\nIf the tool works as described, you have a new way to fill your pipeline without cold-calling. If it doesn’t, you have lost sixty seconds.\n\nWe built this for operators who value precision over speed. We built it for those who need proof, not promises.\n\nTry it. Verify it. Tell us what you find.\n\n[Link to Zambo Stack Portal]\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:159f549ad2c04c8a3ce9430ea63e30d4d4181c9a5b77e9b3c3c3a13546f89d5b","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":"sha256:2ac84856e75865d022e9f06969b275b80ee5359606f2bf65f01588c5a3a58620","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":"sha256:05dcc95a724476ed0a520df6f948f3edff662ae00bf851f8fc62559db17bca85","anchor":{"event_id":"bae9152de0c086d95b262b6153cc3037b884145b636e310e8f0aa84b9b461eba","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-03T04:02:15.226Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-03T04:02:14.149Z","evidence_url":null,"receipt_uuid":"7a36ac2f-b847-461d-bbaa-5d519f7f549a","output_sha256":"sha256:48e75feb769f5e2136024da63c23375b0b6912b6cd7830396558e1c7d51ff0e0","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-03T04:02:14.149Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:48e75feb769f5e2136024da63c23375b0b6912b6cd7830396558e1c7d51ff0e0\",\"receipt_uuid\":\"7a36ac2f-b847-461d-bbaa-5d519f7f549a\",\"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":"2026-11-03T04:02:14.149Z","detail":"The receipt store reports 2026-11-03T04:02:14.149Z; 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.
