I’m writing because Zambo just launched with a different approach: verifiable execution.\n\nWe built Zambo to bridge the gap between intent and completion. It doesn’t just suggest actions; it executes them and provides cryptographic receipts for every step. Whether you’re processing data, scanning for security risks, or researching leads, the output includes a link to a public log. This proves exactly what ran, when it ran, and what the result was. No black boxes. No guessing. Just auditable facts.\n\nRight now, Zambo is live and ready for your workflow. You can test it immediately by asking it to run a simple task—like a semantic analysis or a lead search—and inspect the receipt it generates. If the results don’t match the proof, you don’t pay. That’s the standard.\n\nWe’re not asking you to trust our marketing. We’re asking you to inspect the logs.\n\nTo get started, simply use the phrase: **\"use zambo to hand this over to [client name]\"**. This triggers the handoff protocol, ensuring the final output is packaged with its full audit trail, ready for you to review or share with your team.\n\nThe free tier is unlimited for core execution calls. No credit card required. Just run a task, check the receipt, and see if the proof holds up.\n\nIf the receipts look solid, let’s talk about scaling this into your daily ops. If not, no hard feelings.\n\nBest,\n\n[Your Name]\nHead of Product, Zambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:e827451a17113da1d54f4c56c76a01d2dc2439f941da2584441cd990165d748c","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:a2e5f464f9b1ab79cfcd1393277dc55dc60d1786513b5bd25f3aad4660070b27","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:a6fc8eac3ed17a8c69b0fba39f7a3d4fddd19c8b79d1ec528aefa71181df6d23","anchor":{"event_id":"1b5941d3555df9739e414f89ce385556612e36dc37746e4eca09a6d5c7807184","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-25T16:57:59.699Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-25T16:57:59.140Z","evidence_url":null,"receipt_uuid":"982f89b5-9f6d-415d-9491-a502017d5539","output_sha256":"sha256:b0dc91ff7c8bc247c00fc10da3668261250e2f7a94a1769a7d6f532863693784","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-25T16:57:59.140Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:b0dc91ff7c8bc247c00fc10da3668261250e2f7a94a1769a7d6f532863693784\",\"receipt_uuid\":\"982f89b5-9f6d-415d-9491-a502017d5539\",\"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":"2026-10-25T16:57:59.140Z","detail":"The receipt store reports 2026-10-25T16:57:59.140Z; 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.
