Give it a trade and a city. It returns five qualified leads with contact info in under 60 seconds. No sign-up. No API key. Just results.\n\nWe tested the system today. The infrastructure holds. The logic works. But we are not here to tell you it is perfect. We are here to tell you it is ready for your eyes.\n\nWe ran a live search for web design firms in Austin, TX. The system returned zero source-backed leads. That is the honest output. No invented data. No fake prospects. Just a clean, verified result based on current public data.\n\nYou can verify this yourself. The receipt below proves the execution. It confirms the saved bytes remain unchanged. It does not prove the data is correct. It proves the process was transparent.\n\nWe are launching with three free searches per day per IP. We are not hiding behind a paywall. We are not burying the value. We want you to see how the engine works before you decide if it fits your workflow.\n\nCheck the receipt. Run your own search. See if the leads match your expectations. If they do, we have a conversation. If they don’t, you have lost nothing but a minute of your time.\n\nThe tool is free. The data is public. The value is yours to judge.\n\n[Link: Verify Execution Receipt]\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:7d09499fac20d5e4ede56f840e3a27d56c6750b20ac07619556f2b798d007e48","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":"sha256:4c266b4f5063b0945937cf20df8b070502b99c2c955319eb1fbad6cb2831a36c","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":"sha256:8a5a9e5addf895a39008b52ef9143fef79736962520cdada2a1300318ec5c2d6","anchor":{"event_id":"e9c05509caea03df85eb349aebcc97d56bf12570a35a8ddea673702c7c076e4e","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-31T15:38:43.299Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T15:38:37.267Z","evidence_url":null,"receipt_uuid":"941cf315-9a96-46a3-a062-c9ad4a52c088","output_sha256":"sha256:ff2a31468fa030209d9454b0e0ed0778965618dba0d936e3c6914528a7ef3c7f","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T15:38:37.267Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:ff2a31468fa030209d9454b0e0ed0778965618dba0d936e3c6914528a7ef3c7f\",\"receipt_uuid\":\"941cf315-9a96-46a3-a062-c9ad4a52c088\",\"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":"2026-10-31T15:38:37.267Z","detail":"The receipt store reports 2026-10-31T15:38:37.267Z; 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.
