Zambo Stack is live\n\nHi [Name],\n\nZambo Stack is officially up and running. We focused on speed and utility for local service businesses.\n\nThe core feature, `leadsignal`, generates qualified leads for contractors and local providers. You input a trade and city; it returns five prospects with contact info in under 60 seconds. It supports 24 trades across any US city. There is a free tier of three searches per day per IP. No authentication is required.\n\nWe ran a live test in Austin, TX, for web design. The system processed the request and returned a clear status: no source-backed leads were found in that specific category for that location at that time. This confirms the tool is active, responsive, and capable of filtering for quality. It does not force results; it reports reality.\n\nA receipt link is attached below. It proves the bytes saved during the run. It documents that the system executed the query and stored the response accurately. It does not guarantee the data is correct or that the leads are available for purchase. It is a record of execution.\n\nThis is a research tool, not an outreach engine. It does not send emails. It does not invent customers. It identifies prospects based on public data. If you want to test it, copy the trade and city into the interface. You will see the same speed and transparency we see.\n\nThe universal entry point, `zambo_universal`, is also active. It routes requests through 36 tools including strategy AI, code audits, and market data. It requires no API key or signup. You have 20 free calls per day across all work tools.\n\nStart with one search. See what comes back.\n\n[Your Name]\n\nReceipt: https://zambo.dev/run/cbf1dfe9-2bed-47b7-bbae-3fd1b7efbf67","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:d84331c726db1802d7aab031a0e8e5cb83817b73dee138fb5798b7576e238cca","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":"sha256:450cfbc019de161d46edbcbf8def2f12fc796b7bab141e8adaedfea1aff6fd20","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":"empty","result_source":null,"evidence_source":null,"external_evidence":[],"provenance":{"result_source":null,"evidence_source":null,"evidence_status":"empty","evidence_captures":[]},"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:be71e132b2488ce6e6df9477d5f90860c2eb271cb668dee756863e84a7aaac0a","anchor":{"event_id":"a6c58655834db363525c5fdd12ec6b0be32d04bce1957be6d460c746da606f7f","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-31T23:44:43.002Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T23:44:42.105Z","evidence_url":null,"receipt_uuid":"7d1b0fc9-8af4-4ccb-bd7c-4bd4620e6a82","output_sha256":"sha256:f041c8961e723ac05d6175b2f8d877a7846bc5e9aced4e40178f81eb701b0b27","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T23:44:42.105Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:f041c8961e723ac05d6175b2f8d877a7846bc5e9aced4e40178f81eb701b0b27\",\"receipt_uuid\":\"7d1b0fc9-8af4-4ccb-bd7c-4bd4620e6a82\",\"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":"2026-10-31T23:44:42.105Z","detail":"The receipt store reports 2026-10-31T23:44:42.105Z; 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.
