The Kairos Signal DePIN Data API provides 19 live REST endpoints covering 370 networks and 18,974 live data series — all with provenance receipts.
Free (no key needed): /v1/networks, /v1/network/<SYM>, /v1/supply, /v1/market, /v1/revenue, /v1/provenance, /health
Paid (X-API-Key required): /v1/correlations, /v1/correlations/lead-lag, /v1/indicators, /v1/signals, /v1/digest, /v1/changes, /v1/compare, /v1/history, /v1/health-profile, /v1/grades, /v1/enrichment, /v1/ai-intel

curl https://api.kairossignal.com/v1/supplyAuthentication is a per-IP rate-limited key: first key per IP is free,
3 keys per IP per 30 days, with $5 in free credits and no card. Every endpoint
returns values with the same three fields shown on the homepage:
source (the exact upstream), as_of (when it was read),
and verify_url (a link to the upstream so you can confirm the
number yourself). Aggregates are not blended silently: a value is either
measured from a named source or absent from the response.
What the API does not do: it does not sell signals or predictions on this surface, does not zero-fill missing networks, and does not paper over upstream outages — an absent feed is named in the coverage map instead of being guessed. Daily batches are Merkle-rooted; the day's root is anchored via OpenTimestamps so the contents of any past batch can be proven unchanged.
Who it serves: researchers running diligence on infrastructure networks, index constructors needing supply and revenue series with provenance, and analysts comparing reported dashboards against measured values. If a metric you need is not in the coverage map, the map says so — that is a feature, not a gap in the sales pitch.
