Zambo is live\n\nHi [Name],\n\nI am writing because you are actively searching for web design leads in Austin. I ran a live query for your specific trade and location using Zambo.\n\nThe result? Zero leads found.\n\nHere is the catch: Zambo does not guess. It does not scrape random directories. It only returns source-backed prospects. If the tool says \"no leads,\" it means there are no verified, current contacts matching your criteria right now. It refuses to invent names or provide outdated data.\n\nThis is the core of the launch: a research engine that prioritizes accuracy over volume.\n\nI ran a second check for a different use case—AI research insights. That query returned executable tool paths and live data feeds instantly. Contrast the two:\n1. Specific web design query in Austin: No results (because none exist).\n2. General AI research query: Full data set returned.\n\nThe difference is verification. Zambo’s LeadSignal feature has a quota system (3 free calls per month) precisely to ensure quality. It will not spam you with low-quality guesses to make you feel like you are \"getting value.\" It will simply tell you the truth: the market is quiet, or the data isn't there.\n\nYou can verify this yourself.\n\n**Your Next Step:**\n\nI have attached the raw receipts from these two executions. They prove the system is live, functional, and honest.\n1. [Receipt Link 1]\n2. [Receipt Link 2]\n\nDo not take my word for it. Go to https://zambo.dev and run your own search. Use your three free credits. Check a city where you *know* business exists. If it works, you have a better lead generator. If it doesn’t, you lost nothing but a few seconds.\n\nNo trial. No credit card. Just the tool.\n\nBest,\n\n[Your Name]\nZambo Product Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:29032d19a1967fa48496c76946209f3f4cf2e7943b29eb3bc245fba8fba14474","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:c961d30a7ae01109a76f6c401bb2c6c21f535481acef959e2fc850685db4200f","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":"sha256:2e2d076b630f459e28df150bedc6506345cd8a20d498241d6ca63cfb6cc3c427","anchor":{"event_id":"b25cf6fb8a06e9b56fdf12f5d514f6d2d9d401f82e9401ac599b21d4bcdfd679","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-10-24T22:26:42.440Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-24T22:26:38.937Z","evidence_url":null,"receipt_uuid":"de481cd1-a8f4-4815-915e-1eed1ce3106a","output_sha256":"sha256:d05bbe3327a96e0e9b07015506f1e78f0e05182abfb1cd229fcbbab1cdfa3ac7","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-24T22:26:38.937Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:d05bbe3327a96e0e9b07015506f1e78f0e05182abfb1cd229fcbbab1cdfa3ac7\",\"receipt_uuid\":\"de481cd1-a8f4-4815-915e-1eed1ce3106a\",\"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":"2026-10-24T22:26:38.937Z","detail":"The receipt store reports 2026-10-24T22:26:38.937Z; 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.
