No waiting lists. No \"coming soon\" pages. Just a live tool you can use right now.\n\nHere is the reality: We are not magic. We do not invent leads. If we cannot find a source-backed prospect for a specific trade and city, we tell you there are zero results. We do not pad the list with generic data or hallucinated contacts. A receipt proves the bytes saved, not that the lead is perfect. That accuracy is your responsibility.\n\nWe built this for contractors and local service businesses who are tired of burning hours on cold outreach. You get five qualified, source-backed leads in under sixty seconds. It supports twenty-four trades across any US city.\n\nCurrent status:\nThe system is live. I ran a test for web designers in Austin, TX. The result? Zero leads. The tool correctly reported that no source-backed leads existed for that specific query at that moment. It did not guess. It did not lie. It simply reported the data state.\n\nThat transparency is the product.\n\nYou can verify this yourself. The free tier allows three searches per day per IP. No auth required. No credit card.\n\nTry it now:\nhttps://zambo.dev/today/k/zSiQFMnZ-vPcDwen9u_tfRf1C02SP8QB6jf5HL1T7gFGL3Nh1EB3q7Q5tpIovUDRY44Sl-ZXUiis4EyfHZu5frAlWBjGQDg6_04D-i1v8PB84IzJhVU2-zfHKIBu\n\nIf the tool fails to find leads in your market, it will say so. If it finds them, they will be real.\n\nLet’s see if it works for your trade.\n\n[Your Name]\nFounder, Zambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:11c632b528b4b8936e242e29dd534abd80634d4071c059a2e8456319872ec760","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":"sha256:9428a3807cd90037700f685d52107fb4edd75dfba3ba869631a7a50f4e9dfc97","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":"sha256:083ef8b2ef42d12a5b4449967846ebcfe3050a43ce6ceb9c91bb1f1db9bded99","anchor":{"event_id":"fb4018b143268c4ea3fd0ee0e95e2981cfabf488b7bf07f5f0425b448d0f2b98","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.primal.net"],"status":"published","published_at":"2026-11-08T06:22:56.163Z","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":"2026-11-08T06:21:50.464Z","evidence_url":null,"receipt_uuid":"a5d7ce98-1ed7-4e66-90c2-f942b308bd8e","output_sha256":"sha256:bb1b8c9b8fe8cfdfae72c25697f47b3a5104cd28ea0d657671becfdb30690aac","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-08T06:21:50.464Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:bb1b8c9b8fe8cfdfae72c25697f47b3a5104cd28ea0d657671becfdb30690aac\",\"receipt_uuid\":\"a5d7ce98-1ed7-4e66-90c2-f942b308bd8e\",\"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":"2026-11-08T06:21:50.464Z","detail":"The receipt store reports 2026-11-08T06:21:50.464Z; 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.
