Zambo is live: 60-second lead gen for local services\n\nZambo Stack is officially live.\n\nWe built this to solve one specific problem: contractors and local service businesses waste hours digging through directories for leads that are often stale or inaccurate. Zambo changes that.\n\nGive it a trade and a city. In under 60 seconds, you get five qualified leads with contact info. No fluff. No sales calls. Just data.\n\n**How it works:**\n*   **Specificity:** Supports 24 different trades across any US city.\n*   **Speed:** Results in seconds, not days.\n*   **Access:** Three free searches per day per IP. No signup. No API keys. No credit card.\n\n**A note on data integrity:**\nWe prioritize source-backed prospects. If a lead isn’t verified against public, current sources, it doesn’t make the cut. A receipt is generated for every run, proving exactly what bytes were saved and retrieved. This isn’t a promise of correctness; it’s a verifiable record of the data state at the moment of retrieval.\n\n**Current Status:**\nThe system is operational. In our last test run for web design in Austin, TX, the tool correctly reported zero source-backed leads available at that moment. This is the intended behavior: we do not guess, and we do not pad results with low-quality data. If the data isn’t there, we tell you. That transparency is the product.\n\n**Try it now:**\nYou can access the tool immediately. It is free, requires no authentication, and requires no setup.\n\n[Insert Link to Zambo Stack Entry Point]\n\nThis is a launch. The tools are ready. The logic is sound. The barrier to entry is zero.\n\nTest a trade you know well. Check the receipt. See if the data holds up.\n\nLet me know what you find.\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:399a4f763d81c0a70b7cd99621ff7440bdab41051c1d7c798f3add944c5a0227","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:f02d2c5ae6b4ff67ed5a22159df7a746bd48adc18679f44af8f59afd5b54a314","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":"sha256:67f042060bc1e1c7324d9e0ce9d41382e7339f989f19ab32913894ea05c5e87b","anchor":{"event_id":"4befb722affaf6497b28d1b0e70fa09822b74b91b9bdb9d5eb65454046928048","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"partial","published_at":"2026-11-05T05:29:46.715Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-11-05T05:29:46.163Z","evidence_url":null,"receipt_uuid":"a71c8a8f-ee71-4c54-8e42-1ee2c8bb319e","output_sha256":"sha256:daaa140c91f04a4b60ba04eba4ed34ab22a0b8302fd7fdbc0495285037096b28","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-11-05T05:29:46.163Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:daaa140c91f04a4b60ba04eba4ed34ab22a0b8302fd7fdbc0495285037096b28\",\"receipt_uuid\":\"a71c8a8f-ee71-4c54-8e42-1ee2c8bb319e\",\"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":"2026-11-05T05:29:46.163Z","detail":"The receipt store reports 2026-11-05T05:29:46.163Z; 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.
