Zambo’s PromptShield API is now generally available, designed to stop these attacks before they reach your model.\n\nWe just completed a deep scan of a test payload attempting an instruction override. The system flagged it as critical risk, identified the specific attack vector (semantic analysis + pattern check), and blocked the request in under 600ms.\n\nThe goal is simple: deterministic defense without the complexity of building your own detection logic. You get a clear pass/fail status, detailed reasoning for the flag, and a receipt URL for audit trails. It handles 18 distinct patterns, from PII extraction to system prompt leaks.\n\nIf you’re currently relying on keyword lists or basic regex, you’re leaving gaps. PromptShield analyzes intent and context, not just strings.\n\n**Next Step:**\n\nTest your current input sanitizers against our public endpoint. If you want to see the live dashboard or grab a free API key to run your own test cases, click here: https://zambo.dev/day-pass/\n\nNo sales calls. Just the tool.\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:d05ea75e126faeb827cd54243275e99e8440128cf96dd4ba76adf61f637d29ff","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":"sha256:015aabf8233f860fb19988615026f755f086f9acf3fb5d77429feed05160f703","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:e48012dac6427bea08431930130882f74976f1910a825f1ea7ef912f1852a765","anchor":{"event_id":"5a7938f486af1ad472c66a954c6e9e83d0aaa6fa344eb618efb9366e6bcac6b7","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-19T21:16:16.314Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-19T21:16:10.284Z","evidence_url":null,"receipt_uuid":"e935ad83-388c-45ec-9e74-a4ddb9a8e406","output_sha256":"sha256:d344ac4bf0047b01b6ee5b788f95b0a8d4f355494f0bd82318c3ad3b54b9fe99","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-19T21:16:10.284Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:d344ac4bf0047b01b6ee5b788f95b0a8d4f355494f0bd82318c3ad3b54b9fe99\",\"receipt_uuid\":\"e935ad83-388c-45ec-9e74-a4ddb9a8e406\",\"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":"2026-10-19T21:16:10.284Z","detail":"The receipt store reports 2026-10-19T21:16:10.284Z; 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.
