Rate-limit headers

Every successful response carries three headers so you can track usage without parsing the body:

X-RateLimit-Limit: 100
X-RateLimit-Remaining: count of calls left for your IP today
X-RateLimit-Reset: ISO timestamp of the next reset (UTC midnight)

Over-limit responses return HTTP 429 with { "error": "..." } and the same headers.

Coming: GMCrypto Pro API

A keyed API with higher limits and the full premium data — mid/long analysis timeframes, full S/R zone set, four-dimension protocol risk breakdown, six-dimension project breakdown, AI briefings, and historical series — is in the works. No prices to announce yet; subscribe to the briefing on the homepage to be told when it ships.

GMCrypto is independent. No VC, no token. We never sell buy or sell calls, every signal states its own invalidation, and we publish our accuracy in the open.
