Zambo changes that by prioritizing verifiable execution over vague outputs.\n\nHere is what you get:\n\n1.  **Source-Backed Research.** Zambo does not hallucinate leads or findings. It executes specific research tasks and returns only what the data supports. If a search yields no results, Zambo says so. It never invents contacts to fill a quota.\n2.  **Receipts for Every Run.** Every action generates a unique receipt URL. This isn’t just a log; it’s proof of exactly what was queried, what was returned, and the specific tools used. You can audit the process.\n3.  **Clear Capabilities.** We’ve mapped out tools like `substrate_breakthroughs` for read-only AI research feeds and integrated workflows for products like VeriAI. Each tool has defined access levels and expected outputs. No black boxes.\n\nWe are currently running with a free tier that allows unlimited research calls. This lets you test the depth and accuracy of the data without commitment.\n\n**Your Next Step:**\n\nRun a single, specific research query. Ask Zambo to find public information on a niche topic or a specific market segment. Check the receipt. Verify that the findings match public sources. If the data is clean and the receipt is transparent, you have a tool you can trust. If not, you have zero risk.\n\nZambo is designed for teams who need answers they can defend. Start with one query. Evaluate the proof.\n\n[Link: Try Zambo Free]\n\nBest,\n\nThe Zambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:fbbe3d23de533e195ebe0fcb207eee7a783b8c1d22b8d259412d84126b1010c5","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":"sha256:8aebc2c974a7265a53aa68b55329a3bc1a3b1ba19a21a93f6b843fa6ff333653","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":"sha256:4d3ae38f598fc178f45cd5346bec4b458702022028ced4f65fb6da99a48e6ab2","anchor":{"event_id":"546f06b8d06632cfbcc6962084eb407e0d98f00b1de15fcf6775d03f6a7a4f5d","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-22T13:28:08.057Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-22T13:28:07.492Z","evidence_url":null,"receipt_uuid":"fa1abfc3-892b-4f5c-a0c9-ace29aff5195","output_sha256":"sha256:5e855d6f2ff522bb61b67abc37823dd02e84e07cd21bc1447ac0edf120ebd6f9","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-22T13:28:07.492Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:5e855d6f2ff522bb61b67abc37823dd02e84e07cd21bc1447ac0edf120ebd6f9\",\"receipt_uuid\":\"fa1abfc3-892b-4f5c-a0c9-ace29aff5195\",\"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":"2026-10-22T13:28:07.492Z","detail":"The receipt store reports 2026-10-22T13:28:07.492Z; 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.
