HTX
Huobi rebranded to HTX in 2023, moving its API portal to htx.com/en-us/opend, though the original huobiapi.github.io reference (still live) remains the more complete REST and WebSocket endpoint specification and is kept here as the docs link. Authentication uses an API key with HMAC-SHA256 request signing, access is free beyond trading fees, and there is no separate paid data-API tier.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Stored keyNo key stored
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
