Gemini 与 Coinbase 订单预览和会话撤单控制对比
已验证事实边界
1. Gemini documentation says role-based access control is used to enforce least-privilege permissions across API keys. 2. Gemini API-key authentication documentation says private REST requests use API key pairs and HMAC-SHA384 signatures over Base64-encoded payload headers. 3. Gemini order documentation describes endpoints for creating an order, canceling one order, canceling all active orders and canceling all session orders. 4. Gemini order documentation says cancel all active orders can cancel outstanding orders created by all sessions owned by the account, including UI orders. 5. Coinbase documentation lists Advanced Trade private endpoints that include create order, cancel orders, list orders, list fills, get order and preview orders. 6. A responsible integration comparison separates preview, session cancel scope, all-account cancel scope, key role, signing requirement, final state and non-secret reconciliation evidence.

| Check | What it means | Practical action | Unknown to keep explicit |
|---|---|---|---|
| Preview surface | Coinbase documents preview orders while Gemini's order page points margin users toward previewing order impacts before margin orders | require a documented preview or dry-run equivalent before any mutating order flow | whether every instrument and account mode exposes the same preview semantics |
| Session cancel scope | Gemini distinguishes session cancellation from broader account-wide cancellation | prefer session-scoped cancellation where the automation can define its own session boundary | whether retries reuse a session or silently create a new one |
| All-account cancel risk | Gemini warns that cancel all active orders can affect orders not placed by the API key | document exactly which orders a cancel command can touch before running it | whether UI orders or other bots share the same account surface |
| Permission model | Gemini uses roles while Coinbase maps endpoints to view, trade and transfer permissions | start with the smallest key role or permission that proves the read path | whether a master key or portfolio scope expands beyond the intended automation |
| Signature and nonce | private APIs require signed requests and time or nonce discipline | test local clock, nonce uniqueness and signature fixtures before live order creation | whether retries after a network timeout reuse invalid nonce material |
| Final state evidence | cancellation responses and order-status checks must be reconciled before replacement orders | store endpoint, client id, order id, status, remaining amount and non-secret timestamps | whether partial fills leave residual exposure after a successful cancel response |

控制说明
1. Preview surface
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：Coinbase documents preview orders while Gemini's order page points margin users toward previewing order impacts before margin orders。可执行动作是：require a documented preview or dry-run equivalent before any mutating order flow。仍然未知的是：whether every instrument and account mode exposes the same preview semantics。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. Session cancel scope
这里的含义是：Gemini distinguishes session cancellation from broader account-wide cancellation。可执行动作是：prefer session-scoped cancellation where the automation can define its own session boundary。仍然未知的是：whether retries reuse a session or silently create a new one。
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. All-account cancel risk
这里的含义是：Gemini warns that cancel all active orders can affect orders not placed by the API key。可执行动作是：document exactly which orders a cancel command can touch before running it。仍然未知的是：whether UI orders or other bots share the same account surface。
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. Permission model
这里的含义是：Gemini uses roles while Coinbase maps endpoints to view, trade and transfer permissions。可执行动作是：start with the smallest key role or permission that proves the read path。仍然未知的是：whether a master key or portfolio scope expands beyond the intended automation。
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. Signature and nonce
这里的含义是：private APIs require signed requests and time or nonce discipline。可执行动作是：test local clock, nonce uniqueness and signature fixtures before live order creation。仍然未知的是：whether retries after a network timeout reuse invalid nonce material。
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。
6. Final state evidence
这里的含义是：cancellation responses and order-status checks must be reconciled before replacement orders。可执行动作是：store endpoint, client id, order id, status, remaining amount and non-secret timestamps。仍然未知的是：whether partial fills leave residual exposure after a successful cancel response。
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 every instrument and account mode exposes the same preview semantics
- whether retries reuse a session or silently create a new one
- whether UI orders or other bots share the same account surface
- whether a master key or portfolio scope expands beyond the intended automation
- whether retries after a network timeout reuse invalid nonce material
- whether partial fills leave residual exposure after a successful cancel response
实用结论
Gemini 与 Coinbase 暴露的订单安全控制不同，因此有用的决策不是谁更好，而是先证明哪一种失败模式。Gemini 文档说明 role-based API keys、HMAC-SHA384 private requests、order creation、cancel order、cancel all active orders、cancel all session orders 与 heartbeat 相关撤单行为；其订单页面也提醒 margin users 在下单前 preview order impacts。Coinbase 文档列出 Advanced Trade API endpoints，包括 create order、batch cancel、list orders、fills、get order 与 preview orders，并将权限拆为 view、trade 与 transfer。安全比较应在生产自动化交易前记录 preview availability、session-level cancel scope、all-account cancel risk、API-key role、nonce 或 signing requirement、final order state 与非秘密证据。 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。
