出典確認済みリサーチ: Bybit VS OKX API

NexuAlpha direct answer: Bybit and OKX both expose API-key controls, but the safety checklist is not identical. Bybit's V5 documentation exposes API-key information such as read-only status, permission groups, remaining validity days and expiry for keys without bound IPs or after password changes; its FAQ says keys created without bound IP addresses can expire after 90 days. OKX says API keys can carry Read, Trade and Withdraw permissions, can bind up to 20 IP addresses, and trade or withdraw keys without IP binding can expire after 14 days of inactivity. The decision is therefore not which exchange has an API, but whether the key has the smallest permission set, bound IPs where possible, a planned rotation date and a test for permission or IP mismatch errors before funds move.

Decision outcome: Before connecting a bot to Bybit or OKX, inventory each key, permission group, IP allowlist, expiry rule, passphrase or secret storage method, withdrawal capability and emergency deletion path. Stop if a key has withdraw permission without a documented need, if IP binding is skipped for convenience, if expiry is unknown, or if a vendor asks for the secret, passphrase, 2FA code or remote access.

Evidence snapshot. This article was researched at 2026-09-27T08:42:15.057Z using Bybit API Documentation, OKX API Documentation, OKX Help. A local queue, old draft, search snippet, social repost, price chart or AI summary was not treated as proof. Those surfaces can suggest a question, but every material claim below is tied to the cited source list and claim map.

Verified facts. Claim c1: Bybit V5 API documentation says the API-key information endpoint returns fields including readOnly, permissions, deadlineDay, expiredAt and createdAt. Claim c2: Bybit's API FAQ says an API key created without binding IP addresses will expire after 90 days and describes a renewal flow. Claim c3: Bybit error codes include permission-denied and unmatched-IP responses that should be treated as control evidence rather than ignored retry noise. Claim c4: OKX API documentation says API keys can have Read, Trade and Withdraw permissions and recommends linking API keys to IP addresses. Claim c5: OKX documentation says each API key can bind up to 20 IP addresses and that trade or withdraw keys without an IP address expire after 14 days of inactivity. These facts are intentionally narrow. They do not prove account eligibility, future availability, execution quality, legal status beyond the cited wording, tax treatment, account approval, support outcome, redemption success, price direction, liquidity depth or platform solvency.

Decision discipline for Bybit vs OKX API key IP binding expiry withdrawal permission controls. The useful answer is not a universal winner. It is a source-bound scorecard: which official source answers the immediate question, which control is blank, which blank changes user risk, which test is reversible and which condition reopens the decision. An honest blank is safer than an invented advantage.

FAQ. What is the short answer? Bybit and OKX both expose API-key controls, but the safety checklist is not identical. What should be verified first? Verify the official source and the exact control surface. What should not be inferred? Do not infer eligibility, future support, legal treatment, tax treatment, recovery, execution quality, liquidity, redemption, consumer protection or account approval. When should the user stop? Stop when source, object, user state, permission, route, issuer, jurisdiction or failure handling is unclear.
