No vaporware, no promises. Just working tools with verifiable receipts.\n\nWe built Zambo to automate the unglamorous parts of your workflow—researching prospects, checking tool capabilities, and verifying execution. Every run generates a unique receipt proving exactly what bytes were saved and what actions occurred. A receipt confirms the data integrity, not the quality of the output. That distinction matters.\n\nRight now, three core capabilities are active and free to test:\n\n1.  **LeadSignal:** Sourced lead generation with strict quotas. If it finds no leads, it returns a zero-count status. It does not invent contacts.\n2.  **Capability Search:** Real-time indexing of available tools and their access tiers. It tells you what is callable in-chat versus what requires a manual web step.\n3.  **Substrate Research:** A read-only feed for AI breakthroughs. No side effects, just data.\n\nWe do not claim these tools replace your judgment. They remove the friction of finding the right tool and verifying the result. You decide if the output is correct. The receipt proves the system did what it said it would do.\n\n**Next Step:**\n\nTest one capability today. Pick a niche for LeadSignal or a query for Capability Search. Run it. Check the receipt. If the data matches your expectations, you’re ready to integrate. If not, tell us where it broke.\n\nWe are not asking for your trust yet. We are asking for your verification.\n\nLink to test suite: [Insert Link]\n\nBest,\n\n[Your Name]\n[Your Title]\nZambo","result_preview_integrity":"display_only_not_committed","result_preview_truncated":false,"input_hash":"sha256:aefb4ef15cd0b3222f6a47f1cdd80c61307413dfa05361f1e66b51539c8e2922","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":"sha256:902eb7e86d50a38bdb19f3355fb402b92fd8339d4d15116128723f46536f0bdd","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":"no_upstream_bytes_captured","external_evidence":[],"provenance":null,"provenance_class":"EXECUTED BY ZAMBO","metadata_hash":"sha256:17b459d1c79a8a99181bf68c61417a3be5133bf567bfbec391c810a5e8985161","anchor":{"event_id":"aefab5facbcb5c2deacb7df606addc65a7f6dfa9906902e04135f5dc47d1ec6f","pubkey":"e13475107d30c918ec664adf2ab1141024a22fb35190f82c9e933704fa49af41","relays":["wss://relay.damus.io","wss://nos.lol","wss://relay.primal.net"],"status":"published","published_at":"2026-10-27T19:00:56.436Z","schema_version":"zambo-receipt-anchor/1","envelope":{"anchored_at":"2026-10-27T19:00:55.859Z","evidence_url":null,"receipt_uuid":"67c0dee6-2426-469a-846a-a1e712d45b9c","output_sha256":"sha256:739d1ea3b49f2751b02912044e6d2499b1d199e74dc1604921642f15b5f5ac1f","schema_version":"zambo-receipt-anchor/1","evidence_sha256":null,"evidence_byte_length":null},"envelope_bytes":"{\"anchored_at\":\"2026-10-27T19:00:55.859Z\",\"evidence_byte_length\":null,\"evidence_sha256\":null,\"evidence_url\":null,\"output_sha256\":\"sha256:739d1ea3b49f2751b02912044e6d2499b1d199e74dc1604921642f15b5f5ac1f\",\"receipt_uuid\":\"67c0dee6-2426-469a-846a-a1e712d45b9c\",\"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":"2026-10-27T19:00:55.859Z","detail":"The receipt store reports 2026-10-27T19:00:55.859Z; 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.
