Notes

  • 10-minute server-side cache — poll no more than once every few minutes; the underlying data doesn’t refresh faster than that.
  • Rate-limited to 120 requests/hour per IP, best-effort.
  • Information only — not financial advice. Every signal links back to its full live tool page for methodology.
  • Attribution appreciated (see the attribution field) but not required.

Status badges

Live SVG badges for a GitHub README, forum post, or anywhere an <img> is allowed but JavaScript isn’t. No API key, no iframe — just an image URL.

FAQ

Is the Liquid State Signal API free?
Yes. GET /api/v1/signals is free, public, and requires no API key. It is rate-limited to 120 requests/hour per IP as a soft abuse deterrent.
What data does the Signal API return?
The current regime label and value for every signal in the Liquid State Signal Scorecard — market barometer, BTC cycle phase, funding rate regime, market breadth, BTC dominance rotation, altcoin season, stablecoin supply ratio, mempool congestion, implied volatility, and DeFi TVL regime — each with a link back to its full live tool page.
Do I need to attribute Liquid State when using this data?
Attribution is appreciated but not enforced. The response includes an `attribution` field with suggested credit text and a link back to liquidstate.tech.
Do I need an API key to use the Signal API?
No — the endpoint works with no key at 120 requests/hour. Registering a free API key with an email raises the limit to 1,000 requests/hour.
Can I embed a live status badge in my GitHub README?
Yes. GET /badge/<metric>.svg returns a live, shields.io-style SVG image (e.g. /badge/regime.svg) for any of five signals — no API key, no JavaScript, works anywhere images are allowed, including GitHub READMEs and forum posts.
