Zambo is live: Verify AI output, find real leads\n\nHi [Name],\n\nNo more guessing which AI tools actually work. Zambo just launched, and it solves two specific problems you’re likely facing right now.\n\nFirst, you need to know if your AI output is trustworthy. Zambo provides a cryptographic trust score for any AI-generated text. It’s not just a style check; it’s a verification layer that proves the source and integrity of the data. If you’re using AI for client work or internal reporting, this eliminates the \"hallucination anxiety\" that keeps stakeholders awake at night.\n\nSecond, you need leads that exist. Our LeadSignal tool searches for source-backed prospects. We don’t invent contacts. If we don’t find a verified lead, we tell you exactly that. We ran a test for web design pros in Austin, Texas. The result? Zero leads. The system confirmed this with a receipt. That’s the difference: we provide proof of absence, not fake data.\n\nZambo also includes \"Substrate,\" a research feed that tracks live AI breakthroughs. It’s read-only, safe, and helps you stay ahead of the curve without digging through noisy news feeds.\n\nYou can start using these features immediately. The core research and lead finding tools are free to access on the standard tier. You get full transparency on every request, including detailed receipts that show exactly what the system checked and what it found.\n\nReady to see the difference between speculation and verified data?\n\nOpen your browser and go to [Link to Zambo Dashboard] to run your first check. Pick a topic or a city, hit execute, and look at the receipt. If it doesn’t give you clear, actionable proof, tell me why I’m wrong.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Company Name]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:109df441ee559866c672a03d5282a8f5ad8c05f970bd99aa43fcfdc362b121bb","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":"sha256:10a197607987b23ba4f22b1eb233acf02adbe05a21a3e5ed2f262c677482baf1","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:b15616004ae9c74da862ca85cf8e85c01cf6b9892dc0b5d7c4cf4363ab290316","anchor":{"event_id":"8a4c84ef96503e66522d58c6a7b78c4480c620fde0a13944863275b7b76e25e5","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-21T13:06:25.979Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-21T13:06:25.415Z","evidence_url":null,"receipt_uuid":"543e4ec4-c252-41f0-91a0-81325a757279","output_sha256":"sha256:9a558fb0637b5bac19d303e9856fad71c355747b368794de037398bfe8fa8711","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-21T13:06:25.415Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:9a558fb0637b5bac19d303e9856fad71c355747b368794de037398bfe8fa8711\",\"receipt_uuid\":\"543e4ec4-c252-41f0-91a0-81325a757279\",\"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":"2026-10-21T13:06:25.415Z","detail":"The receipt store reports 2026-10-21T13:06:25.415Z; 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.
