如何安全设置 Bybit API Key 的只读权限与 IP 限制
已验证事实边界
1. Bybit Integration Guidance documents V5 API authentication expectations and system-generated API-key behavior. 2. Bybit Get API Key Information documentation describes an endpoint for retrieving API-key metadata and permission-related information. 3. Bybit Error Codes documentation includes permission-denied and key-expiry labels that can be recorded without exposing secrets. 4. Bybit Rate Limit Rules documentation provides the source for request and traffic-limit planning before a production bot is enabled. 5. A read-only and IP-restricted onboarding flow is a safety procedure derived from the documented surfaces, not a guarantee that an account is eligible for every feature. 6. This tutorial does not ask the reader to reveal API keys, passwords, identity documents, one-time codes, seed phrases, tax identifiers or account balances.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Read-only first | read-only testing limits the blast radius of a new integration | create or select the smallest available scope and test metadata retrieval before any trading flow | whether the account UI maps scopes exactly to API endpoint behavior |
| IP restriction | IP binding reduces exposure but can break mobile, cloud or failover paths | bind only approved fixed infrastructure IPs and document exception windows | whether failover infrastructure will use a different source IP |
| Error evidence | permission and expiry labels can guide recovery without exposing credentials | capture code, endpoint, time and non-secret environment label | whether support-side account state is required to explain the error |
| Rate-limit budget | a safe key can still create outages if polling ignores limits | set per-endpoint budgets, backoff, alerting and a kill switch | whether another integration shares the same IP or UID quota |
| Evidence stop rule | API-key onboarding is not credential collection | never paste keys, passwords, identity documents, one-time codes or balances into tickets or prompts | whether enabling trade or funding permissions materially changes the risk |

控制说明
1. Read-only first
这一项要求读者把公开来源翻译成操作规则。这里的含义是：read-only testing limits the blast radius of a new integration。可执行动作是：create or select the smallest available scope and test metadata retrieval before any trading flow。仍然未知的是：whether the account UI maps scopes exactly to API endpoint behavior。因此本文不会把未知部分包装成收益承诺、牌照承诺、审批保证、安全保证、恢复保证、平台排名或价格暗示。
2. IP restriction
这里的含义是：IP binding reduces exposure but can break mobile, cloud or failover paths。可执行动作是：bind only approved fixed infrastructure IPs and document exception windows。仍然未知的是：whether failover infrastructure will use a different source IP。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
3. Error evidence
这里的含义是：permission and expiry labels can guide recovery without exposing credentials。可执行动作是：capture code, endpoint, time and non-secret environment label。仍然未知的是：whether support-side account state is required to explain the error。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
4. Rate-limit budget
这里的含义是：a safe key can still create outages if polling ignores limits。可执行动作是：set per-endpoint budgets, backoff, alerting and a kill switch。仍然未知的是：whether another integration shares the same IP or UID quota。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
5. Evidence stop rule
这里的含义是：API-key onboarding is not credential collection。可执行动作是：never paste keys, passwords, identity documents, one-time codes or balances into tickets or prompts。仍然未知的是：whether enabling trade or funding permissions materially changes the risk。
操作测试也必须很窄。这就是本文坚持以清单形式呈现的原因。
仍需明确的未知项
- whether the account UI maps scopes exactly to API endpoint behavior
- whether failover infrastructure will use a different source IP
- whether support-side account state is required to explain the error
- whether another integration shares the same IP or UID quota
- whether enabling trade or funding permissions materially changes the risk
实用结论
安全的 Bybit API-key setup 应从 read-only scope、fixed IP planning 与 non-secret evidence 开始，而不是先开 broad trading permissions。Bybit V5 文档提供 integration guidance、API-key information fields、permission and expiry error labels 与 rate-limit rules。实际 onboarding flow 是：选择最小 key scope，在可能时只绑定已批准 infrastructure IP，先测试 read-only endpoint，记录非秘密 error label，定义 rotation owner；除非账户、司法辖区与 integration 已有单独证据，否则在启用 trade 或 funding permissions 前暂停。 本文停在证据边界内，帮助读者决定下一步核验什么，而不是把公开文档改写成私人账户、钱包、API key、池子路径、稳定币余额、代币化资产或政策框架在任何未来条件下都能成功的承诺。
