API docs

Public JSON endpoints.

The read-only endpoints that power the public pages are open to use — no key required. They are rate-limited per IP and the shapes below may evolve with the product, so treat this as a beta API.

Base URL: https://www.tethertracker.pro
Rate limits: per-IP limits apply to every endpoint; heavy callers get 429. Responses are CDN-cached — polling faster than once a minute buys you nothing.
Authenticated data: the live whale feed (/api/recent-transactions) and alert APIs require a signed-in subscriber session and are not part of the public surface.
