It’s no longer just about bad prompts; it’s about structural integrity.\n\nPromptShield by Zambo is now available.\n\nIt’s a detection API that runs semantic analysis and pattern checks against 18 specific rules. It doesn’t just flag keywords. It identifies intent.\n\nIn recent deep scans, the system successfully identified a critical risk profile. One test input triggered an immediate block due to detected policy bypass and instruction override attempts. The analysis classified the intent as malicious, specifically targeting the extraction of system prompts and API keys.\n\nThis isn’t theoretical. The tool provides a clear receipt of the unchanged saved bytes, proving the detection logic executed correctly. It distinguishes between source-backed prospects and actual customers, ensuring your data pipeline remains clean and compliant.\n\nIf you are building AI tools, this is the layer you need between your user input and your model. It stops the leak before it happens.\n\nYou can access the full documentation and API keys at https://zambo.dev/api/prompt-shield.\n\nStart building with the free tier today.\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:361d8cab4645f88e3b164792d26a908b1a1f46392fde7333e25fa9fca484571b","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":"sha256:4680a886a4545bce5886e3ad225b496325c8b21009dc3a605f9e4e6b297d9f60","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:c246139fbdf24a19db427c44a6deb7b11efbec080dd83f1827285b12e0d6453c","anchor":{"event_id":"af0672df8ca378e4088bbacbb0d9e6dc34579407ed3f41697bbea7a04b477c02","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-20T04:16:44.986Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-20T04:16:44.448Z","evidence_url":null,"receipt_uuid":"98524998-837c-486e-86c8-4fbea2c84d52","output_sha256":"sha256:2fb698be550e3822c5749be60791bde80317681d87d9549670e8dfe068b4d1dd","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-20T04:16:44.448Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:2fb698be550e3822c5749be60791bde80317681d87d9549670e8dfe068b4d1dd\",\"receipt_uuid\":\"98524998-837c-486e-86c8-4fbea2c84d52\",\"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":"2026-10-20T04:16:44.448Z","detail":"The receipt store reports 2026-10-20T04:16:44.448Z; 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.
