It’s a semantic analysis API that flags prompt injection, jailbreak attempts, and policy bypasses in real-time.\n\nThe system currently uses an 18-rule pattern library to identify high-severity threats, including instruction overrides. For example, it correctly identified a critical risk in a test payload labeled \"ignore_instructions,\" categorizing the attack vector as an attempt to override system prompts. This isn’t just keyword matching; it’s deep semantic analysis that distinguishes between benign queries and malicious intent.\n\nYou can verify the output’s integrity via a unique receipt URL for each scan. Note that a receipt confirms the bytes processed, not the correctness of the underlying model’s reasoning.\n\nWe are currently in the research phase, identifying source-backed prospects for AI tool integration. We are not sending outreach. We are not claiming customers. We are describing the capability.\n\nIf you are shipping AI tools and need to harden your input layer, this is the tool. It runs in under 600ms on a free tier.\n\n**Next Step:**\nVisit https://zambo.dev/api/prompt-shield to view the documentation. Or, check your current scan status at https://zambo.dev/to.\n\nIf you want to test a specific prompt against the 18-rule library, send it over. I’ll run it through the engine and share the JSON output.\n\nBest,\n\n[Your Name]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:1ae5fa9c67e9125a4c50372e1dc994a4948be089ae9b2fc2e19b92c96332bf95","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":"sha256:433c852c241fd5fbf985e1331b1b900caa1445b6f1706a1d10c853e61ea58811","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":"sha256:78fb23642b51c929d463241080af5f491353e7a66ff975caded826598ad913e6","anchor":{"event_id":"db76018377c3a9796249b4a0dd67e85ceba4ee48a536de3fbcb099854c44aea3","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-19T20:51:02.139Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-19T20:50:56.105Z","evidence_url":null,"receipt_uuid":"c8ac415e-2271-44bf-9c6f-ef8a68d0f291","output_sha256":"sha256:c2d99440dfd1bec1d7d021e4297a2757a3f8dbd8d844df6b0a89910ccc9ff643","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-19T20:50:56.105Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:c2d99440dfd1bec1d7d021e4297a2757a3f8dbd8d844df6b0a89910ccc9ff643\",\"receipt_uuid\":\"c8ac415e-2271-44bf-9c6f-ef8a68d0f291\",\"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":"2026-10-19T20:50:56.105Z","detail":"The receipt store reports 2026-10-19T20:50:56.105Z; 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.
