It flags malicious intent and policy bypasses immediately. The engine processes these checks in just 1512 milliseconds.\n\nThis is not a beta. It is a functional guardrail.\n\nWhen a prompt attempts to jailbreak your system or leak sensitive data, PromptShield blocks it before execution. It categorizes the threat vector—like instruction override—and provides a clear severity rating. You get a definitive yes or no on safety without slowing down your user experience.\n\nThe receipt from our test run verifies the unchanged saved bytes. It proves the system logged the threat and the decision accurately. It does not claim the blocked content was correct, only that it was dangerous.\n\nWe are not sending this to customers. We are sharing this with prospects in the AI tooling space who are currently building without this layer of defense. You have seen the logs. You know the risk.\n\n**Next Step:**\n\nRun your own test case. Visit https://zambo.dev/api/prompt-shield to see the live detection in action. We have 12 calls remaining on the free tier for this specific scan. Use them to verify the latency and accuracy on your own prompts.\n\nDo not guess if your AI is safe. Test it.\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:e1224b81cbfc3f5431bd2ab116b1fbebb067a756fe876ea27deea7b036df651e","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:e810344b6be1c2493487bd516e7c5ede7202f5abb1170bde527a8d4e1250f55c","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":"sha256:0c992819dd66b9fe7fac0f5505a561a7d0252a882a5078876031da85b4e3f061","anchor":{"event_id":"33887cbd4992eb278cdfd92908229f2e6da5fec3409ab5ac23aa2abe91e8fc0a","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-16T13:20:40.228Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-16T13:20:39.682Z","evidence_url":null,"receipt_uuid":"b2c1903a-5a02-489c-9056-6566959daf49","output_sha256":"sha256:591c7292028cebb2a572f051e4c78c9d9b864403512d6454ae476cb3b5545783","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-16T13:20:39.682Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:591c7292028cebb2a572f051e4c78c9d9b864403512d6454ae476cb3b5545783\",\"receipt_uuid\":\"b2c1903a-5a02-489c-9056-6566959daf49\",\"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":"2026-10-16T13:20:39.682Z","detail":"The receipt store reports 2026-10-16T13:20:39.682Z; 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.
