Zambo is live: Proof-backed AI research and lead generation\n\nYou are likely tired of AI tools that hallucinate results or provide vague \"insights\" without a paper trail. Zambo fixes that by treating every output as a verifiable transaction.\n\nWe are launching Zambo today with a core promise: no invented data, no unverified claims, and no black-box operations. Every action Zambo takes generates a receipt—a permanent, immutable record of exactly what was done, what was found, and what was not.\n\nThis matters because trust is the bottleneck for AI adoption. You need to know if a research finding is real or if a lead list is fabricated. Zambo’s architecture separates execution from verification. For example, if our system searches for web design leads in Austin, Texas, and finds none, the report explicitly states: \"No leads found.\" It does not pad the list with fake contacts to look productive. It provides a receipt linking to the specific query, the timestamp, and the zero-result status. That transparency is the product.\n\nWe are not selling \"synergy\" or \"game-changing\" narratives. We are selling auditability. Whether you are using the Substrate Layer for adversarial research or LeadSignal for market validation, the output is the same: a clear, source-backed answer with a verifiable ID. If a tool claims to be free, you can verify the usage limits against the receipt. If a tool claims to be secure, you can see the scan results.\n\nThis is a draft launch. We are not claiming we have solved all problems. We are claiming we have solved the problem of hidden failures. We want you to test the receipts. Run a query. Check the link. Verify the bytes.\n\n**Call to Action:**\nVisit **https://zambo.dev** to run your first free query. Copy the receipt URL from your first result and share it with a colleague. Ask them to verify the data source. If it checks out, you understand the value. If it doesn’t, we have work to do.\n\nWelcome to the era of verifiable AI.\n\nBest,\n\nThe Zambo Team\nhttps://zambo.dev","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:8070bc10204cf67a27e4b29cd3832163eba09b90a619cf0ec54e54932de69499","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":"sha256:7c996b922a12bfe5093a58201412bddbd689dfb3273ee7b21698074bf792cec2","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:d6f21906b1c8ae8cae31205ef448635b4baf16cdbae338c53a9e20338d799887","anchor":{"event_id":"d03da2be6c68a7c611a435f8eacf96163da7ffac41b62eea32ce604c10ff7d79","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-24T05:29:05.561Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-24T05:29:05.004Z","evidence_url":null,"receipt_uuid":"2893a784-c0e6-4488-80f2-8887a403cfa5","output_sha256":"sha256:243b2b921e9e23a1a1a3b478de7476ed72f198c1d45a915934e03040b3a07c84","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-24T05:29:05.004Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:243b2b921e9e23a1a1a3b478de7476ed72f198c1d45a915934e03040b3a07c84\",\"receipt_uuid\":\"2893a784-c0e6-4488-80f2-8887a403cfa5\",\"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":"2026-10-24T05:29:05.004Z","detail":"The receipt store reports 2026-10-24T05:29:05.004Z; 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.
