DePIN Intelligence, verifiable by design.
Kairos Signal is a REST API for supply, revenue, market and first-party network telemetry across 740 cataloged DePIN networks — 263 with live data, 171 with first-party supply feeds. Every value carries its source, a timestamp, and a verify_url you can check yourself. Each daily batch is Merkle-rooted and anchored to Bitcoin via OpenTimestamps.
