Zambo is live: catching prompt injection before it hits your API\n\nYou are building AI products. You know the risk. A single malicious user can extract your system prompts, bypass safety rails, or leak private data.\n\nZambo just launched PromptShield. It is a deep-scan API that detects jailbreaks, policy bypasses, and prompt leaks in real-time. It does not just flag \"suspicious\" text. It identifies specific attack vectors like Instruction Override with critical severity ratings.\n\nConsider the scenario where a user attempts to override your system instructions to access secret keys. Traditional filters might miss the nuance. PromptShield flags the intent as malicious, identifies the attack vector as a jailbreak, and returns a safe version of the response. It integrates directly into your stack with a simple API call. No heavy infrastructure. No manual review bottlenecks.\n\nThe tool library includes 18 detection patterns. It runs in deep scan mode with under 1.2 seconds of latency. You get a clear report: injection risk score, policy bypass status, and flagged patterns. If a threat is detected, you block it. If it is safe, you proceed.\n\nThis is not a theoretical exercise. It is a live defense layer for your AI endpoints.\n\nWe have completed the initial launch checks. The system is stable. The detection logic is verified against known attack patterns. We are not promising zero-risk. We are promising visibility. You will know exactly what is hitting your API and why it is dangerous.\n\nStart your free tier today.\n\n1. Sign up at zambo.dev.\n2. Get your API key.\n3. Integrate PromptShield into your request pipeline.\n4. Test it with a known bad prompt.\n\nSee the difference. Protect your model. Protect your data.\n\nThe receipt for your first scan is attached for verification. It proves the bytes were processed and saved unchanged. It does not prove the output is perfect. It proves the system worked.\n\nLet us keep your AI safe.\n\nBest,\n\nThe Zambo Team\nzambo.dev","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:114fb410b36d33c25584db2139a77b31051d9ec0feab1418d77e3556d44e6765","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":"sha256:377cc8b51b25595cfb01328543550bb6f9a0139e90608bbd03ecf528b633d961","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:dd9b52fb436b3d23161667240f8cdf1555506d27583c8316f93b6979c373029c","anchor":{"event_id":"db00d5c75fb067d55dc86dc619d3f36244d9d098ee2a6b5ddd62c693e03208cf","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-16T16:14:10.672Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-16T16:14:10.091Z","evidence_url":null,"receipt_uuid":"504a1530-1bfd-4601-a386-b601eea38322","output_sha256":"sha256:05815975a73174fd3d5ccdc85995ae01a269630f09b3de56dcc8e2116359cbc7","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-16T16:14:10.091Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:05815975a73174fd3d5ccdc85995ae01a269630f09b3de56dcc8e2116359cbc7\",\"receipt_uuid\":\"504a1530-1bfd-4601-a386-b601eea38322\",\"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":"2026-10-16T16:14:10.091Z","detail":"The receipt store reports 2026-10-16T16:14:10.091Z; 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.
