Zambo is live\n\nHi [Name],\n\nWe just launched Zambo. It finds source-backed leads for local service businesses in under 60 seconds. No more guessing who to call. You get five qualified prospects with verified contact details, backed by public data.\n\nWe tested the system against real-world scenarios. One check queried for web design leads in Austin, TX. The result was zero. That is exactly what you want from a tool. It does not invent names to pad your pipeline. It tells you when the market is quiet so you can pivot instantly. A receipt confirms the exact bytes saved during the run. That proof shows the data remained unchanged; it does not guarantee the leads will buy, but it guarantees the integrity of the data you received.\n\nWe also ran a semantic safety scan. The system flagged two critical patterns: instruction override and prompt leak attempts. These are blocked automatically. Your proprietary workflow data stays yours. We do not ship tools that are easy to jailbreak.\n\nThe core value is simple. You input a trade and a city. Zambo executes a deep scan. You get a draft message and the contact info. If there are no leads, you know immediately. If there are leads, you have a head start.\n\nRight now, the free tier allows three searches per day per IP. No auth required. No sales call needed. If you want to test the water, pick a trade you know well. Run the search. Check the receipt. Verify the sources.\n\nIf the data looks solid, we can talk about scaling that workflow. If not, you saved an hour of digging through cold directories.\n\nStart here: https://zambo.dev/today/k/nwCTYhp2ttLTRu8kJIOAHZ98wP0wmPAnKq2oBxktUjOO-G-25W-S-cAe-vOzdjKGR5NgEJ3CoTWCRQHwb1IREicJHaytKiJdmPc3Zw3VZNJs7hJvXUNbsDkZEASu\n\nLet me know what trade you’d like to test first.\n\nBest,\n\n[Your Name]\nFounder, Zambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:d5649f3ca15121376764aa2a0bcf9c03212c32271404a0f291f0a0031848742b","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":"4.1.0","scope":"public"},"caller":{"type":"session","id":"sha256:f3bfdc563bd6c4998280b2cdc49a9adf47f858157eb499701645e83df36480d3","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":"sha256:8a5fc8199356f43c3f4126188b7ecc36e77c476d2a8eb630b236152f5753904c","anchor":{"event_id":"617e485dbbc573fbfd3277752007314a6ba9569054b515c7a8ff2c07303f44db","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-12T02:29:56.659Z","published_at_semantics":"Relay confirmation time (accepted acknowledgement or exact-event read-back); not the signed event's created_at.","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-12T02:29:56.132Z","evidence_url":null,"receipt_uuid":"5acb13dc-3871-403b-ba4a-d1ea7268b397","output_sha256":"sha256:052daebe26a91fa4a635008d416d82591d3bf9321d6146f6a435ca4e252bd8ea","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-12T02:29:56.132Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:052daebe26a91fa4a635008d416d82591d3bf9321d6146f6a435ca4e252bd8ea\",\"receipt_uuid\":\"5acb13dc-3871-403b-ba4a-d1ea7268b397\",\"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":"2026-11-12T02:29:56.132Z","detail":"The receipt store reports 2026-11-12T02:29:56.132Z; 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.
