It scans inputs against 18 semantic and pattern-based rules to flag malicious intent before your model processes it.\n\nWe tested it on a live launch scenario. The system correctly identified a critical risk level, detected a jailbreak attempt, and flagged an instruction override pattern. It returned a safe version of the prompt and blocked the execution. This isn’t just a keyword filter. It analyzes intent and context to distinguish between a user trying to break your system and a user asking a complex question.\n\nYou can integrate it with a single API call. It runs in under a second, so it won’t add noticeable latency to your user experience. The free tier is unlimited, so you can test it against your own traffic immediately.\n\nIf you’re building AI tools, this is a necessary part of your stack. We built it to be transparent. You get a full receipt for every scan, including the reasoning behind the block. No black boxes.\n\n[Link to Docs]\n\nCheck out the API docs if you want to see how it works. Let me know if you have questions.\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:c006aaf474a237335330cc1afef8fec8987dfde0e4d01d34ff452c1e110a73cd","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":"sha256:7c49d2cc62e43745358605a2ba0eecadf6423a272e9f6d9278ff4fbbf23f48d1","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:aecd443b471402d80edacde91eb1b0e133e5311707288593d862da2cb08b76ee","anchor":{"event_id":"feca5bbe122c1edc936c52d3311344b7a304327b70b30c658124c56e1e407eea","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-20T04:26:46.000Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-20T04:26:45.268Z","evidence_url":null,"receipt_uuid":"4fd1e8f1-1dc7-44e4-a943-ec81238f71e7","output_sha256":"sha256:1651822b91c5eeeea1a0f2117ce9a8dfda8acb9bbe8b50cb53d69282f797b92b","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-20T04:26:45.268Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:1651822b91c5eeeea1a0f2117ce9a8dfda8acb9bbe8b50cb53d69282f797b92b\",\"receipt_uuid\":\"4fd1e8f1-1dc7-44e4-a943-ec81238f71e7\",\"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":"2026-10-20T04:26:45.268Z","detail":"The receipt store reports 2026-10-20T04:26:45.268Z; 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.
