DePIN Intelligence for Research & Diligence | Kairos Signal

# Kairos Signal — Verifiable DePIN Data API > A machine-readable DePIN (Decentralized Physical Infrastructure Networks) + physical-world data product for AI agents and MCP clients. > 727 networks cataloged, of which 369 carry live data — 305 of the networks first-party, read straight > from the network's own endpoint or chain. That is 12,091 live series, refreshed > continuously, with daily snapshot history on 369+ live networks plus 129 Bittensor subnets (1703 distinct SN series; browsable per-subnet pages at /subnet/SN8.html, full index /sitemap-subnets.xml). > Catalog entries without live data yet are labelled `catalog_only` in /v1/networks so you can > filter them out in one line. > Every value carries {symbol, metric, value, unit, source, verify_url, as_of}. The verify_url points to the UPSTREAM > source it was read from — the network's own API, CoinGecko, or DefiLlama — so you can check any number without trusting us. > Each daily batch is Merkle-rooted and timestamped to Bitcoin via OpenTimestamps. This is a DATA product: no trading > signals, no performance/return/accuracy claims. Measured 2026-08-24. ## What this is (and is not) - IS: measured DePIN infrastructure facts — supply, price/market cap, protocol fees/revenue, TVL, and per-network operational telemetry — each with provenance and an upstream verify_url. - IS NOT: a trading signal or a prediction product. No win-rate, edge, return, or accuracy figures are published anywhere. ## Access - REST API + MCP endpoint are LIVE and self-serve. Register at POST https://kairossignal.com/v1/credits/register — instant, no approval, $5 free credits (first 3 keys per IP per 30 days), no card. - New agents receive $5 in free credits (first 3 keys per IP per 30 days) on registration (no card). 1 credit = 1 USD. - A public per-value verification endpoint (Merkle inclusion proofs) ships with the public API. Until then, every value is still checkable at its verify_url upstream. ## Verifiable receipts
