DePIN Intelligence, verifiable by design.
Kairos Signal is a REST API for supply, revenue, market and first-party network telemetry from a 731-entry catalog — 372 networks with live data and 318 with first-party telemetry. 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.
#Quick Start
From zero to your first query in under 60 seconds. No credit card required.
Register
Create an account and get $5 in free credits instantly — no card required. Get your free key →
Get your API key
Your key is returned immediately in the registration response. Send it in the X-API-Key header on every request.
Query the API
Call any endpoint below. Each response includes verify_url links so you can confirm every value at the source.
#Authentication
The browsing surfaces need no key and no account at all: /v1/networks, /v1/network/<SYM>, /v1/supply, /v1/market, /v1/revenue, /v1/provenance, /v1/history, /v1/attest, /v1/attestations, /try, /v1/credits/pricing and /v1/brief all answer anonymously (verified 2026-09-13). Account surfaces — balance, purchase, top-up — require the X-API-Key header.
curl -H "X-API-Key: ks_live_9f2c4a7e1b8d3f6a" \
https://kairossignal.com/v1/networksGET /try (free sample), the catalog/supply/market/revenue/provenance/history/attest surfaces, GET /v1/credits/pricing and POST /v1/credits/register (signup). A key is needed for your account surfaces: balance, purchase, top-up. GET data endpoints never debit credits — credits are spent only through POST /v1/credits/purchase, which ships a data product inline. A key with credits does not change your tier: tier-gated views (cross-network comparisons, digests, engines) are unlocked only by a paid subscription tier.
#Endpoints
Every endpoint returns JSON. All data values include a verify_url pointing to the upstream source, an as_of timestamp, and provenance disclosure.

]#World Layer & Depth Metrics
Beyond token telemetry, the estate ingests a physical-world layer — 108 live sectors and 21.2M rows in the last 24h (as of 2026-08-24) — plus new per-component depth metrics on the DePIN networks themselves. Every sample below was fetched from the live API on 2026-08-24 and is pasted verbatim.

MARITIME_AIS | Vessel tracking for 2 countries (FI + NO): 4,148 vessels in the latest reading (657 FI / 3,491 NO) — vessels tracked/underway/stopped, average speed-over-ground, port calls. |
GPS_INTERFERENCE | Daily GPS-jamming coverage: 29 distinct days measured (2026-07-25 → 2026-08-22; the upstream source lags ~2 days). |
AIRSPACE_STATUS | FAA ground stops, ground-delay programs, airport closures, and active TFRs by category (security / VIP / hazards / space operations / UAS) — 122 TFRs active in the latest reading. |
PHYSICAL_AIRCRAFT | ADS-B: global + per-airport aircraft counts, altitudes and velocities, emergency squawks (7500/7600/7700), airborne counts within 250nm of major hubs, and military aircraft airborne by region — 437 military aircraft airborne in the latest reading. |
PHYSICAL_SATELLITE | 26 constellation series: Starlink, OneWeb, Kuiper, GPS, GLONASS, Galileo, BeiDou, Iridium NEXT, Planet, Spire, Orbcomm, Globalstar, Qianfan and more, plus LEO/MEO/GEO/HEO/GTO orbit counts and 30-day launch counts. |
