Hyperliquid vs Upbit Open API

Hyperliquid 39

Read as a closed hosted service with open SDKs. The API has no dated changelog, so the last dated change is the Python SDK's 0.24.0 on 4 June 2026, 152 days before this check; the node repository was pushed on 10 August 2026 and the docs describe newer actions (HIP-4 outcome markets, borrow and lend) without dates. Judgement call (10 of 30). No three dated releases in 90 days (0). Support through Discord and the docs' FAQ, 112 open issues on the SDK whose replies couldn't be read (8 of 25). Official Python and Rust SDKs, the Rust one last pushed 21 October 2025; no MCP registry entry (15). CI on Python 3.9 and 3.13 with Poetry, Dependabot badge, a lock file (6 of 10). Total 39.

Upbit Open API 83

Read as a closed service. SDK v1.1.0 on 20 October 2026 (30). The CLI 1.0.0 on 1 September, the rate-limit update of 7 October, the SDK on 20 October and the path-format notice for 16 November 2026 (20). open-api@upbit.com answers in turn on weekdays per the support notice, notices carry dates, and the six upbit-official repositories show no open issues (12 of 15). Current official SDKs in Python, TypeScript and Go (15). Apache-2.0 repositories pushed in October 2026; CI not checked (6 of 10). 30 + 20 + 12 + 15 + 6 = 83.

Hyperliquid 55

No machine payment protocol (0). Fees published per tier without login (20). No card anywhere; public info endpoints are free and the testnet faucet gives 1,000 mock USDC, though only to an address that has deposited on mainnet (15 of 20). No signup; an agent with a funded EVM wallet deposits USDC on a bridged chain and trades, subject to the unread terms (20). Total 55.

Upbit Open API 15

No machine payment protocol (0). The fee schedule is on upbit.com, which disallows every crawler path, so no price is recorded (0 of 20, unchecked). Public quotation endpoints need no key, card or account; trading needs a verified Korean account. Judgement call (15 of 20). A person must sign up, pass identity checks and issue keys on the PC web site (0). 0 + 0 + 15 + 0 = 15.

Hyperliquid 26

The editorial half. The SDKs are MIT and the node repository Apache-2.0 with a Dockerfile around a binary; the API servers and front end are closed and the terms were unreadable (12 of 30). No privacy policy read and nothing in the docs on data handling (0 of 30). Deprecated actions are marked in the docs without dates or a policy (8 of 20). No subprocessors or data locations (0 of 20). Total 20.

Upbit Open API 54

The editorial half. A closed service whose user and Open API terms could not be fetched under upbit.com's robots.txt, and whose SDK licence page calls the SDK material not open source while the repositories carry Apache-2.0 (8 of 30). The developer centre's privacy policy names Dunamu Inc., gives retention periods and names Zendesk in Japan; the main privacy policy was not read (14 of 30). Notices with effective dates, including the path-format change and the deprecated Remaining-Req min field (12 of 20). Zendesk and Google Analytics named with a location for the developer centre only (8 of 20). 8 + 14 + 12 + 8 = 42.

Hyperliquid 42

No OpenAPI or other machine-readable contract; request and response shapes are tables and JSON examples in the docs (0 of 25). llms.txt and a Markdown twin of every page by appending .md (10). Each info type and exchange action has a short description of what it does, and the signing page lists common mistakes, but little says when to use one call over another (12 of 20). Fields are one-letter keys (a, b, p, s, r, t, c) with numbers as strings, enums such as tif Alo, Ioc or Gtc, and required fields marked in tables (9 of 15). An example for every call and a list of order and cancel error strings, with no HTTP error table (11 of 15). No API version, no changelog and no dated release notes; deprecated actions such as userDexAbstraction are marked in place (0 of 15). Total 42.

Upbit Open API 66

No OpenAPI found; the reference is a readme.io site with a Markdown twin of every page (5 of 25). llms.txt on docs.upbit.com and a kr/llms.txt index (10). Each reference page states what the endpoint does, its group and its errors, with warnings such as market_offline after maintenance (14 of 20). Typed parameters with enums for order type, side and time in force and required flags (11 of 15). Recipes in Python, Java and Node.js and an error format of error.name and error.message with HTTP statuses (13 of 15). Feature versions in page histories (v1.6.1) and dated notices with effective dates, no single API version (13 of 15). 5 + 10 + 14 + 11 + 13 + 13 = 66.

Hyperliquid 64

No shared secrets. Actions are signed by the wallet key or by an API wallet the master approves with a name and optional expiry; API wallets can only sign, withdrawals and external sends are user-signed, and approving a new wallet deregisters the old. No IP allow-list or address allow-list (24 of 30). An API wallet is a trading-only credential and info needs no key, but nothing limits order size or marks an action as needing approval (10 of 20). The API returns no untrusted content (10). Fills, historical orders, userRole and nonces are queryable per account; no per-wallet action log (8 of 15). A bug bounty run by the Hyper Foundation with rewards up to under 1 million USDC, a Zellic audit of the bridge contract, a SECURITY.md on the SDK; no security.txt (403), no SOC 2 (12 of 20). Total 64.

Upbit Open API 59

Keys limited to chosen functions, a mandatory public IPv4 allow-list, a JWT per request with a fresh nonce, keys listed with expiry through the API, and a withdrawal safe-lock on by default (27 of 30). Read-only keys, the default withdrawal lock lifted only in the app, and skills that require a typed CONFIRM before writes (17 of 20). The API returns exchange data and announcements, no third-party content (10 of 15). An API key list endpoint; no per-call log for the operator (5 of 15). No disclosure policy, bug bounty or certification found; security.txt on upbit.com could not be fetched under its robots.txt (0 of 20). 27 + 17 + 10 + 5 + 0 = 59.
