Zambo is live: Critical risk detection in under 2 seconds\n\nHi [Name],\n\nZambo’s PromptShield API is out of beta. It identifies prompt injection, jailbreak attempts, and policy bypasses in real-time.\n\nThe threat landscape has changed. Attackers no longer just ask for bad outputs; they try to override system instructions to exfiltrate API keys or steal private context. Traditional filters miss these semantic shifts. Zambo does not.\n\nOur engine runs deep semantic analysis against a library of 18 specific attack patterns. It flags instruction overrides, data extraction attempts, and malicious intent with 95% accuracy. A recent scan of a standard user query identified a critical \"Instruction Override\" attempt in 1,477 milliseconds. The system correctly blocked the request, flagged the attack vector, and returned a safe, compliant response without exposing internal system prompts.\n\nThis is not just a filter. It is a security layer for your AI infrastructure.\n\nWe are currently onboarding a limited number of source-backed prospects to test the API in production. If you are building AI tools, agents, or chatbots, you need this protection.\n\n**Next Step:**\nReply with \"Audit\" and I will send you a link to run a free, read-only scan on one of your current prompts. No credit card. No commitment. Just data.\n\nBest,\n\n[Your Name]\nZambo\nhttps://zambo.dev\n\n**Why this works:**\n*   **Direct:** No \"I hope you are well.\" Gets straight to the problem (injection/jailbreaks).\n*   **Specific:** Uses the exact metrics from the brief (1,477ms, 95% accuracy, 18 patterns) to prove capability without inventing fake customer wins.\n*   **Clear CTA:** \"Audit\" is a low-friction, high-value action.\n*   **Tone:** Friendly but professional. Confident but not arrogant.\n*   **Safety:** Explicitly states it is a \"read-only scan\" and \"no commitment,\" building trust.","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:59dda2dd833850a2d03fae69c31d0e924328c00dedb21bea49bdc4b00114dd72","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":"sha256:746aec6a86e1e6d4ebcc0b50e83cf5b301f277256148f051f39a92800f8d6151","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":"sha256:3f68d0b912ea9afd55d4d8516f9550f00317a65fb4e79d8e909a31a91312a40e","anchor":{"event_id":"bafc03ad8fed1fc23db2821ed9fa528cfb4da1cdc24e46670920dc03f4c8728c","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-18T05:49:46.919Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-18T05:49:44.506Z","evidence_url":null,"receipt_uuid":"be7ebd28-e03e-4087-a260-5a7f5988121a","output_sha256":"sha256:d7683c5ada1d0ab8d2098b09c8517764b563cc616b04937167e9663f3b5bb701","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-18T05:49:44.506Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:d7683c5ada1d0ab8d2098b09c8517764b563cc616b04937167e9663f3b5bb701\",\"receipt_uuid\":\"be7ebd28-e03e-4087-a260-5a7f5988121a\",\"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":"2026-10-18T05:49:44.506Z","detail":"The receipt store reports 2026-10-18T05:49:44.506Z; 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.
