It is a free, no-signup AI lead generation tool for contractors and local service businesses. Give it a trade and a city, and it returns five qualified leads with contact info in under 60 seconds.\n\n**What the data shows:**\n*   **Status:** Live and operational.\n*   **Cost:** Free. No API key. No signup.\n*   **Limits:** 20 free calls per day across work tools.\n*   **Current State:** The system is ready for execution.\n\n**A note on recent tests:**\nA scan for web design leads in Austin, TX returned zero results. This is a data availability issue, not a system failure. The tool works; that specific niche in that specific city is currently empty in the source data.\n\n**Proof:**\nYou can verify the system’s responsiveness and receipt generation via this live run:\nhttps://zambo.dev/run/91c2e496-6eae-4359-982d-9d301f6c7fb0\n\n**Next Steps:**\nPick a trade with high local demand (e.g., plumbing, HVAC, roofing) and a major metro area. Run the search. If you hit a zero-result count, change the city or trade. Do not interpret empty data as a product bug.\n\nThe tool is built for speed and direct access. Use the 20 daily free calls to validate your specific market segments.\n\nReceipts prove the bytes were saved and the request was processed. They do not guarantee the quality of the returned data. You are responsible for verifying the leads before outreach.\n\n**CTA:**\nRun your first search for a high-demand trade in your target city today.\n\nBest,\n\n[Your Name]\nZambo Team","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:ef32360f9b412c9c5fb0d64fb29334eba29b350b8f48005b905e28bbb1387eeb","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":"sha256:6430d248b4198bc512158132071f9cfb5b19a0eb685569a91d363dd0075b91eb","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:e218b643c6de804a19bd4f7af4b206e12ffdcd9d78129ed51c7e220230170c11","anchor":{"event_id":"3e8cfc9b5908a65708aefd5e8b38a65eb7c174d4af9b97f4697147b016f18eef","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-01T07:41:27.959Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-01T07:41:27.427Z","evidence_url":null,"receipt_uuid":"424edf38-f092-44f4-a91e-1a38947223e4","output_sha256":"sha256:16d6378739d1bdb5ff33ce5f09e1dcb649eb8f4efeed8f20629ee640aa05021b","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-01T07:41:27.427Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:16d6378739d1bdb5ff33ce5f09e1dcb649eb8f4efeed8f20629ee640aa05021b\",\"receipt_uuid\":\"424edf38-f092-44f4-a91e-1a38947223e4\",\"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":"2026-11-01T07:41:27.427Z","detail":"The receipt store reports 2026-11-01T07:41:27.427Z; 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.
