It targets contractors and local service businesses who need qualified leads without the agency overhead.\n\nThe core promise is speed and specificity. You input a trade and a city, and Zambo returns five qualified prospects with contact information in under 60 seconds. It currently supports 24 trades across any US city. There is no authentication and no signup required. The free tier allows three searches per day per IP.\n\nWe ran a live test on the Austin web design market today. The system processed the request and returned zero results. This is a critical distinction: the tool functioned correctly to query the source, but the current data set did not contain matching source-backed prospects. An empty result is not a failure; it is accurate reporting. We do not invent customers. We do not pad lists with generic data. If the source doesn’t have it, Zambo says so.\n\nThis transparency is the product. You get verified, source-backed prospects or a clear signal to shift your geographic or trade focus. No guesswork. No wasted outreach. No fake leads.\n\nI want you to run this test yourself.\n\n**CTA:** Visit [Link to Zambo] and search for \"Plumbers\" in \"Denver, CO.\" Check the timestamp. Note the source citations. If you find a prospect, verify the contact info. If you find none, trust the signal.\n\nWe are monitoring the free tier usage closely. The system is stable, the checks are passing, and the data integrity is non-negotiable. Let’s see what your niche looks like.\n\nBest,\n\n[Your Name]\n[Your Title]\n[Link to Zambo]","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:b0138f9c1d299f5f95463d203fe3b69faabcd4c5f119adcceb37de18b3a6f2e4","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":"sha256:585d70cd057f483e4bb80297e2413c31fd5d05d95a11ea4346fcc86ea889458d","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:c6fe34c3c09d149382ecd194bc68f34a61838933e2f85b22a0e565fe6fbede00","anchor":{"event_id":"94e8aecf22e69b04f58f4193a8588959e404816c372ace0109b8486b2ce46d1e","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-31T00:53:11.992Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-31T00:53:11.442Z","evidence_url":null,"receipt_uuid":"a6fd0037-e599-4e52-acaa-05fa8cb44226","output_sha256":"sha256:4ecba4eaff5364e10b5be04ed00caacf9bae36ef2eab6d6e5f2c5c06944261cf","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-31T00:53:11.442Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:4ecba4eaff5364e10b5be04ed00caacf9bae36ef2eab6d6e5f2c5c06944261cf\",\"receipt_uuid\":\"a6fd0037-e599-4e52-acaa-05fa8cb44226\",\"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":"2026-10-31T00:53:11.442Z","detail":"The receipt store reports 2026-10-31T00:53:11.442Z; 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.
