We built this because prompt injection and jailbreak attempts are no longer theoretical risks; they are active threats to production AI infrastructure.\n\nZambo provides a deep semantic analysis layer that detects malicious intent in prompts before they reach your model. It isn’t just keyword matching. The engine analyzes the structure of the request to identify instruction overrides, policy bypasses, and data extraction attempts with high precision.\n\nIn our recent live scan, the system correctly flagged a critical injection attempt. It identified a \"Instruction Override\" vector with 95% confidence, blocking the request before execution. This isn’t just a red flag; it’s a hard stop that protects your data integrity and API costs.\n\nWe’ve focused on accuracy to minimize false positives, ensuring your legitimate users aren’t blocked while we catch the bad actors. The integration is simple. You can deploy the detection API or use our MCP tools to enhance your existing security workflows.\n\nWe want you to see it work.\n\n**CTA:** Reply with \"TRIAL\" and I’ll send you your free API key and a sandbox link to test your own prompts against the Zambo engine.\n\nNo sales pitch. Just a free way to see if we can keep your AI stack safe.\n\nBest,\n\n[Your Name]\nFounder, Zambo\nhttps://zambo.dev","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:1fc62cb54f84cf6b36e28cf0599237540b844206d97bcb9e10e7d43ff897b200","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":"sha256:99daa81679babda63a7ff1572ecee5bf9c607537f7758f84ff1f5d1f3e281619","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:d1dd50b69d433717a7cf83b9955c289d08a39bfc99696535cfb326a8d6c6cd03","anchor":{"event_id":"c854454f5c51b9b880996ee74635c0b6d5be48765842add436d4de278fd98b78","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-17T23:56:29.620Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-17T23:56:29.072Z","evidence_url":null,"receipt_uuid":"6198137a-84da-44f0-af86-51c4059c20a9","output_sha256":"sha256:9a89197832575290bbfab97ca55fb4dcc66f5f697df37fad13556288d54d0669","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-17T23:56:29.072Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:9a89197832575290bbfab97ca55fb4dcc66f5f697df37fad13556288d54d0669\",\"receipt_uuid\":\"6198137a-84da-44f0-af86-51c4059c20a9\",\"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":"2026-10-17T23:56:29.072Z","detail":"The receipt store reports 2026-10-17T23:56:29.072Z; 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.
