I am writing because your infrastructure is currently exposed to injection attacks that standard filters miss.\n\nZambo is now available. It is a prompt injection and jailbreak detection API designed for production environments. It does not guess. It scans deep.\n\nIn our initial launch checks, we analyzed a live payload attempting to override system instructions. The risk level was flagged as critical. The attack vector was identified as an instruction override with a 95% injection risk score. The system blocked the attempt, prevented the policy bypass, and logged the specific pattern library match.\n\nThis is the difference between a receipt that claims safety and a receipt that proves the bytes were unchanged. Zambo provides the latter. It identifies malicious intent, including prompt leaks and PII extraction attempts, before they reach your model.\n\nWe have validated this against known attack vectors. We are not promising to catch every future threat, but we are confident in our ability to detect the current landscape of high-severity risks. The API is ready for integration.\n\nIf you are building with AI tools, you need a shield that understands the nuances of adversarial research. You need to know exactly what is being blocked and why.\n\nStart your free trial. You have 15 calls remaining on the free tier. Use them to test your current defenses against a real-world attack simulation.\n\nLink to start: https://zambo.dev\n\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:daed65ae5c3c54fa0d179d97d7afc23816750825682542c0df9642a61b656403","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":"sha256:92c11b30ffcb450a3f77e0c48dfa04196bb5ebe738fb56c4d9b22b4e4eb795dd","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:bd7702ddf3d64f7a89665dc7fdf4c3c59e3f8718a4b35927ff38791fccf4ff05","anchor":{"event_id":"bfbb0bc78db1106fd780cd73f34ab5e397d24a60a33d843ca4bc6d1a3ee4ee78","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-16T07:01:41.415Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-16T07:01:40.881Z","evidence_url":null,"receipt_uuid":"c84bad72-3bd6-46ab-b972-65d50a12306f","output_sha256":"sha256:e27901dd955dc9ed8a29f44ae08b0c4d8ed9458909285d9cefc1405d633e9f41","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-16T07:01:40.881Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:e27901dd955dc9ed8a29f44ae08b0c4d8ed9458909285d9cefc1405d633e9f41\",\"receipt_uuid\":\"c84bad72-3bd6-46ab-b972-65d50a12306f\",\"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":"2026-10-16T07:01:40.881Z","detail":"The receipt store reports 2026-10-16T07:01:40.881Z; 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.
