We built it to solve one specific problem: AI tools that promise automation often deliver unverified outputs and hallucinated data. Zambo provides cryptographic trust scores for AI-generated content and source-backed lead generation, ensuring every result is traceable to a public receipt.\n\nWe ran a live test today to demonstrate this transparency. Our LeadSignal tool searched for web design prospects in Austin, Texas. The system returned zero results. Instead of inventing contacts to fill the quota, Zambo reported the exact failure, proving that our output reflects reality, not fabrication. You can verify this specific run via the attached receipt link.\n\nThis level of auditability is rare in the current AI landscape. Most platforms hide their logic or generate plausible-sounding but factually incorrect data. Zambo exposes the underlying mechanics. If a tool fails to find a lead, it tells you. If it finds one, it proves the source.\n\nWe are currently offering unlimited free access to our core research and signal tools. This includes the Substrate Layer for adversarial research and the LeadSignal engine. There is no credit card required, and no hidden paywalls on the free tier.\n\nIf you are tired of guessing whether your AI outputs are accurate, Zambo gives you the proof.\n\n**Next Step:**\nReply to this email with \"Access\" and I will send you your unique login link and the receipt from today’s test run so you can verify the security architecture yourself.\n\nBest,\n\n[Your Name]\nFounder, Zambo\n[Link to Zambo Landing Page]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:c7b30f769acb8ece3a794a7629d2bbb6cd402b175d1a5e28c5511e3a4984cb3e","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":"sha256:4ad90a806883899644db69c9b67f9569e5b76b7ec4bcda21827a55bed1e301c0","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":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:f783af3e185f74075868464865d2339acb4399907a69320ffe577f3058c87461","anchor":{"event_id":"b55aaf8299ed4e60e79c65fd89950a882e76c1bbef6e15ac19119c488f283074","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-22T09:07:45.875Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-22T09:07:45.263Z","evidence_url":null,"receipt_uuid":"fcce7d5e-ee93-4375-b306-7255c7068adc","output_sha256":"sha256:fb6767c92ff8ee33ae2264c1e1adbdb0fe5c1b4af2131e8f8561510d474c5ad1","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-22T09:07:45.263Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:fb6767c92ff8ee33ae2264c1e1adbdb0fe5c1b4af2131e8f8561510d474c5ad1\",\"receipt_uuid\":\"fcce7d5e-ee93-4375-b306-7255c7068adc\",\"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":"2026-10-22T09:07:45.263Z","detail":"The receipt store reports 2026-10-22T09:07:45.263Z; 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.
