Zambo is live: verified, transparent, and free\n\nHi [Name],\n\nYou asked for clean, source-backed intelligence without the noise. That is exactly what Zambo delivers.\n\nWe just launched the universal entry point for the Zambo Stack. It routes your requests through 35 distinct tools via a single MCP connection. No API keys. No signup. No hidden costs. Just immediate access to strategy AI, code audits, lead generation, and live market data.\n\nHere is the reality of the current environment: most AI tools promise magic but deliver guesswork. Zambo operates on proof. Every execution generates a tamper-proof receipt. This document verifies the exact bytes saved and the specific logic applied. It does not claim a task is complete; it shows you the work. It distinguishes between suggested actions and executed results.\n\nConsider our recent test run. We queried for prospective web design leads in Austin. The system returned zero results. A lesser tool might have hallucinated a list to look helpful. Zambo returned the truth: no source-backed leads currently exist for that specific query. It then provided a valid receipt proving the search was performed correctly, even though the outcome was empty. That is the standard. We do not invent customers. We do not fabricate fixes. We provide verified data or a clear explanation of what must still run.\n\nThis transparency is the product. You get a concrete route for your request. If a live read-only branch is available, it executes. If not, the system tells you exactly which downstream tool to call. You remain in control. Zambo works with your host AI, not instead of it.\n\nWe are offering 20 free calls per day across all work tools. This is not a trial period to upsell you later. It is the baseline.\n\nThe launch is active now. The infrastructure is stable. The receipts are public.\n\n[Link to Zambo Dashboard]\n\nStart with one query. Check the receipt. Verify the logic.\n\nBest,\n\n[Your Name]\nFounder, Zambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:62c99745feed8c38486809a8a421e57ef3fde965c981ecb82d4135f767e39675","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:c7f34ca0263d94b2b0de7128e94d3fc1d270f5abeb88b166ecac1ae89463c4a2","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":"sha256:7e448f7e8bca3df15d9802931caaab7c8f4e3072dd5415541a3f4871acc15855","anchor":{"event_id":"781a847b05279296504fbb8b5bb0ee4153fb354b4ff19b0460e545e3db2e9675","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-30T05:12:31.054Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-30T05:12:30.427Z","evidence_url":null,"receipt_uuid":"2b203476-58a0-4476-a85a-a0937e79819e","output_sha256":"sha256:554e4f51d276eae92a35942bcea3ef17e2e90af49d28796a18491304fd1b93c7","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-30T05:12:30.427Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:554e4f51d276eae92a35942bcea3ef17e2e90af49d28796a18491304fd1b93c7\",\"receipt_uuid\":\"2b203476-58a0-4476-a85a-a0937e79819e\",\"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":"2026-10-30T05:12:30.427Z","detail":"The receipt store reports 2026-10-30T05:12:30.427Z; 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.
