Zambo just launched. It’s built for people who need verifiable results, not vague assurances.\n\nHere’s what it does:\n1. **Source-Backed Prospecting:** It finds real leads. If it can’t find them, it tells you. No invented contacts. No fake data.\n2. **Deep Safety Scans:** It checks for critical risks like prompt injection and PII leaks before you hit send.\n3. **Proof of Work:** Every action comes with a receipt. You see the bytes. You see the logic. You see the result.\n\nWe tested the lead signal for web design in Austin. The system executed, checked the sources, and returned zero leads. It didn’t guess. It didn’t make up names. It gave you the truth: no source-backed leads exist right now. That’s the difference. You trust the tool because the tool shows its work.\n\nZambo isn’t a black box. It’s a transparent engine. Whether you’re researching AI tools or scanning for security risks, you get clarity.\n\n**Your next step:**\nTry it on your current workflow. Run a search. Check a document. See the receipts. If the proof doesn’t hold up, tell us. We’ll fix it.\n\n[Link to Zambo Platform]\n\nThanks,\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:9fa8fd05ecf97e113f187486c4b78ec2873dfeb85f7a1d87093995382d71915d","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:b425a6563f4532e40c0a512f94b9029d384b75ee9dd361f3e01fcfb18f6a7df1","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":"sha256:8698d467304ec83854005476f42185e8e1fc5e707f8b9a1ab1e77e59bd6ba807","anchor":{"event_id":"402f42c72679805c438baa1b673667479fa6af46b2bd6f6f0fba50099217ed37","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-24T09:29:08.041Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-24T09:29:07.476Z","evidence_url":null,"receipt_uuid":"37e8be78-1d8d-45bf-9b39-0753d25e77c9","output_sha256":"sha256:415ac550ebda55f864120bdf9db7134b724aa6907f7077c5bc36d4f0179fb2f5","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-24T09:29:07.476Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:415ac550ebda55f864120bdf9db7134b724aa6907f7077c5bc36d4f0179fb2f5\",\"receipt_uuid\":\"37e8be78-1d8d-45bf-9b39-0753d25e77c9\",\"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":"2026-10-24T09:29:07.476Z","detail":"The receipt store reports 2026-10-24T09:29:07.476Z; 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.
