It is a lightweight, API-first security layer designed to intercept and analyze prompt injection attempts before they reach your core LLM logic.\n\nWe built this because standard guardrails often miss semantic attacks or fail to provide actionable receipts for compliance teams. Zambo checks incoming prompts against 18 distinct pattern rules, including instruction overrides and data extraction attempts. It does not just block; it documents. Every analysis generates a timestamped receipt proving exactly what was detected, how it was classified, and why it was flagged. This creates an immutable audit trail without slowing down your user experience.\n\nWe are currently onboarding a small cohort of early adopters to help refine detection thresholds. We are specifically looking for teams who are already handling high-volume user inputs and need a clear, defensible record of their security posture. This is not a general beta; it is a targeted launch for partners who can provide real-world feedback on edge cases.\n\nIf you are interested in seeing how Zambo handles the specific attack vectors mentioned in our recent public research (such as the \"ignore_instructions\" pattern), I have prepared a sandbox environment for you. You can run your own test cases against it and review the generated receipts in real-time.\n\nReply with \"Sandbox\" and I will send you the API key and a brief technical overview. No sales call required. I will only follow up once if you do not reply within five business days.\n\nBest,\n\n[Your Name]\nFounder, Zambo\nzambo.dev","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:a6db338968677bac0cb1a22d0746c21a706a082f21ecf67f3fbfe5110ea447d1","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":"sha256:8a2a114ee809f9ceb957f4c9f57893f327e31bb82329798abf3bd586c49d406d","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:ddb929246e65730aa5b8afb1b4286c9a9727115e9d3bc2c895d27fad8909f7ba","anchor":{"event_id":"83f929398c90c424e9373e716ca5f27a46017eb90c375203dea37e843d7dc325","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-19T22:16:41.866Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-19T22:16:41.306Z","evidence_url":null,"receipt_uuid":"3f4bc053-d456-489a-b8a0-5c7e04f47169","output_sha256":"sha256:587ded3c99f2c225f4cb7d78b492a56612d607de0ae6ce67160d16c9f4c8c021","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-19T22:16:41.306Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:587ded3c99f2c225f4cb7d78b492a56612d607de0ae6ce67160d16c9f4c8c021\",\"receipt_uuid\":\"3f4bc053-d456-489a-b8a0-5c7e04f47169\",\"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":"2026-10-19T22:16:41.306Z","detail":"The receipt store reports 2026-10-19T22:16:41.306Z; 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.
