Give an AI trading bot the narrowest API key it can use: read-only while you connect and test, then trading permission only when it must place or cancel orders. Keep transfers, withdrawals, account management, margin and futures disabled unless a documented workflow genuinely needs them. Restrict the key by IP where the exchange supports it, store the key material like a password, and review or revoke it regularly. An AI model does not create a special security boundary. The bot can do whatever the exchange allows that key to do, whether its decisions are sensible, its software is compromised, or its configuration is wrong.
What an exchange API key actually controls
An API key is a credential that lets software call an exchange on your behalf. The exchange authenticates the key, checks its scopes and restrictions, and then accepts or rejects each endpoint request. The bot does not receive an independent “AI” permission set; it inherits the key’s capabilities.

A stolen or misconfigured key is therefore a form of delegated account access. A read-only key may expose balances, order history and other account data. A trading key may place or cancel orders. A key with transfer or withdrawal authority can move value, while an account-management key may alter settings. The exact names and boundaries differ by exchange, product, account type and region.

Kraken’s support guidance states, “API keys are equivalent to your Kraken username and password.” That description is specific to Kraken’s warning about the sensitivity of keys, not a claim that every exchange implements authentication identically. Treat the key, secret and passphrase as credentials with the same care as your sign-in password.

Before creating anything, write down the bot’s required actions. Separate actions that only read data from actions that submit or cancel orders, and separate both from actions that move funds or change account settings. If you cannot explain why a permission is needed, leave it off.
Permission types: start with the smallest useful scope
| Capability | What it normally permits | Safe default for a trading bot | Important qualification |
|---|---|---|---|
| View, read or account data | Balances, orders, fills, positions, market or account information | Enable first for connection, configuration and dry-run testing | The data exposed varies by exchange and endpoint. |
| Trade or order | Submitting, amending or cancelling orders | Enable only when the bot must trade | On Binance, TRADE is an endpoint security type for trading actions; trading is disabled for a new key until enabled in API Management. |
| Transfer or withdrawal | Deposits, withdrawals or other value transfers | Keep disabled for an ordinary trading bot | Coinbase Exchange says its Transfer permission includes value transfers and bypasses 2FA. |
| Manage or account settings | User-setting or credential-management actions | Keep disabled | Only a specifically documented administrative workflow should require it. |
| Margin, futures or derivatives | Product-specific trading and account actions | Keep disabled unless that product is the bot’s stated purpose | These scopes can be exposed separately from spot trading. |
Binance documents endpoint security types and gives TRADE and USER_DATA as examples. A key can be limited to selected secure endpoint types; it cannot trade by default until trading is enabled. Read the current Binance Spot REST API security documentation before selecting scopes, because endpoint requirements are not interchangeable with another exchange’s labels.

Define the bot’s required operations
List each API call or feature the bot vendor documents: reading balances, reading market data, placing spot orders, cancelling orders, reading positions, or anything else. Mark every item as read, trade, transfer or account management. If the vendor asks for a broad permission without explaining the operation, ask for a narrower configuration or do not connect the account.
-
Create a dedicated key
Do not reuse a personal integration key. Create one key for this bot, give it a clear label such as “paper-test” or “spot-bot-production,” and keep production and test environments separate where the exchange permits. A separate key makes usage easier to attribute and lets you revoke the bot without breaking unrelated software.
-
Begin read-only
Enable View, Read or the equivalent account-data scope first. Connect the bot, confirm that authentication works, and check that the data it receives is limited to what you expect. If the bot cannot operate without trading rights during setup, use a sandbox or the smallest practical account exposure rather than granting transfer rights.
-
Add only the order-trading scope
When the bot must submit or cancel orders, enable Trade or the exchange’s equivalent. Do not enable Transfer, Withdrawal, Manage, margin or futures simply because they appear beside Trade in the creation screen. On Binance, trading is a distinct permission from user-data access; on Coinbase Exchange, Trade is distinct from Transfer and Manage.

-
Allowlist the bot server’s outbound IP
Find the fixed public IPv4 or IPv6 address used for outbound API traffic and enter only that address or the smallest necessary set. Confirm the address is stable before saving the key. A changing cloud, home or mobile address can lock the bot out; a broad network range weakens the restriction. If the exchange does not offer IP restrictions for the key type, compensate with narrower scopes, secret storage and monitoring rather than assuming an IP control exists.
-
Save the secret and passphrase securely
Put the API key, secret and passphrase in a reputable password manager or an encrypted secrets store. Inject them into the bot through its supported secret configuration; do not paste them into chat prompts, source control, tickets, screenshots, shell history or ordinary logs. Coinbase Exchange says the secret key and passphrase are shown only once, so copy them into protected storage during creation and verify that you can retrieve them before closing the page.
-
Test the least dangerous operation
First test authentication and read requests. If order access is required, verify that the bot can submit and cancel only the intended product and account type, using the smallest practical exposure. The exchange documentation establishes the distinction between read and trade scopes, but it does not guarantee that any particular test amount makes a bot safe.
-
Record and review the configuration
Keep a private record of the key label, owner, permitted product, allowed IP addresses, creation date and intended bot. After connection, inspect the exchange’s permission summary and activity history. Set a calendar review, and delete keys that no longer have a clear owner or purpose.

Keep value-moving permissions off
A trading strategy normally needs to create and cancel orders, not to move assets between wallets or withdraw them. Transfer and withdrawal permissions turn a trading credential into a potential funds-extraction credential. Coinbase Exchange defines Transfer as value transfer, including deposits and withdrawals, and states that this permission bypasses 2FA. That makes it inappropriate for a normal order-only bot.
Binance exposes separate flags for withdrawals, internal transfer, spot and margin trading, margin and futures in its account-permission response. Seeing a flag in an API response does not mean every account, region or API product exposes the same control, so verify the controls shown in your own API Management screen. If a workflow truly requires a transfer, use a separate, purpose-built key with the shortest possible lifetime and a tightly restricted process; do not add transfer rights to the key used for routine trading.
IP restrictions, 2FA and secret storage
IP allowlisting
An IP allowlist limits where a key can be used, which helps when a secret leaks but the attacker cannot originate requests from the approved server. It does not protect a compromised bot host, and it does not replace least privilege. Check the bot host’s actual egress address, not its private network address, and test after saving the restriction.

Coinbase Exchange requires an IP address whitelist field when creating a key. Binance’s help documentation says IPv4 IP access restrictions are mandatory to enable withdrawal permission and describes additional rules that depend on key type. Those rules can change: Binance records a policy effective date of , under which a system-generated key could be set only to reading if its IP was unrestricted. Check the current account screen and regional documentation rather than relying on that historical rule.
Two-factor authentication
Use account 2FA and API-key 2FA when the exchange offers them. A hardware FIDO2 security key can be an optional sign-in factor if your exchange and bot service support it, but it does not narrow API permissions and cannot make a withdrawal-enabled key read-only. Coinbase Exchange requires 2-step verification during its key-creation flow; Kraken recommends API-key 2FA where available and 2FA on the third-party service itself.
Credential handling
Restrict access to the secret store to the bot process and the few operators who need to rotate it. Mask secrets in logs, disable debug output that prints request headers, and check that crash reports do not include environment variables. Never send a secret to support in plain text. If a vendor asks for the secret through an informal channel, stop and use its documented credential-entry method instead.
Exchange-specific controls
Binance
Binance’s Spot REST documentation assigns a security type to each endpoint. USER_DATA covers account or user data, while TRADE covers actions such as placing and cancelling orders. New API keys cannot trade until trading is enabled in API Management. Select only the endpoint types the bot needs, and verify the resulting summary after creation.
The account-permission endpoint reports fields for IP restriction, reading, withdrawals, internal transfer, margin, futures and spot/margin trading. These are response fields, not a promise that every account or product presents identical switches. Use the current account interface and the current API documentation when checking a key.
For the endpoint model and current security-type requirements, see Binance’s General REST API Information. For the permission response, see Binance’s Account–Wallet REST API documentation. Binance’s key-creation guidance, including IP-restriction rules, is at How to Create API Keys on Binance?.
Coinbase Exchange
Coinbase Exchange limits a key to one portfolio and requires an IP address whitelist field and 2-step verification during creation. Its permission table distinguishes:

Kraken
Kraken warns that API access can expose sensitive account information and permit actions such as placing or cancelling orders, deposits and withdrawals. Its recommendations include minimal permissions, reputable password-manager or encrypted storage, API-key 2FA when available, 2FA on the third-party service, regular key creation with limited scopes and deletion of keys that are no longer relevant. The complete guidance, updated March 31, 2025, is in Kraken’s API Key Security article.
For an implementation-level check, Kraken’s Get API Key Info endpoint can return a key name, permissions, restrictions, allowed IP addresses or ranges and usage timestamps. Use that information to compare the live credential with your intended configuration, rather than trusting an old setup note.
Separate keys, accounts and environments
Use different keys for development, paper testing and production. If the exchange supports separate portfolios or subaccounts, map each key to one clearly defined environment. A read-only monitoring service should not share a key with an order-execution process, and a spot bot should not share a key with a derivatives service.
Labels should identify both purpose and owner. Keep a private inventory with the key’s creation date, scopes, IP allowlist, exchange product and rotation contact. When staff, vendors or infrastructure change, review the inventory rather than assuming old credentials are still needed.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Monitoring and rotation
Review permissions and recent use after the first connection, after every bot update and on a recurring schedule appropriate to the account. Look for unexpected order types, symbols, cancellations, login or API activity from an unfamiliar address, and requests outside the bot’s normal hours. Monitoring cannot undo a withdrawal, but it can shorten the time between abnormal activity and revocation.

What to do if a key may be exposed
- Stop the bot so it cannot continue sending requests while you investigate.
- Revoke the suspected key immediately in the exchange’s API-management page. If the exchange offers a “revoke all” emergency action, understand that it may disconnect unrelated integrations.
- Review account activity for orders, transfers, withdrawals, setting changes and unfamiliar IP addresses.
- Contact the exchange through its official support channel if there is unusual activity or a possible funds movement.
- Rotate related credentials, including the bot host’s secrets, account password and 2FA recovery material if those may also have been exposed.
- Rebuild with narrower permissions only after identifying how the credential leaked or why the bot behaved unexpectedly.
Binance advises revoking all keys and contacting support when unusual activity is noticed. The exact emergency controls and support process vary by exchange, so keep the official recovery links available before an incident.
Troubleshooting common setup failures
Authentication succeeds but account data is empty
Check that the key has the exchange’s View, Read or USER_DATA permission and that it is tied to the intended portfolio, account or product. Confirm the bot is calling the correct regional API endpoint and that its server clock meets the exchange’s request requirements. Do not solve a read problem by enabling withdrawals or account management.
Orders are rejected even though the key is valid
Verify that Trade is enabled, the symbol and product match the key’s account, and the bot’s IP address is on the allowlist. On Binance, trading must be explicitly enabled in API Management. A read-only key can authenticate successfully while every order request is rejected.

Re-check the server’s public outbound address, including changes caused by failover, a cloud NAT gateway or a new hosting region. Add only the confirmed addresses required by the deployment, then test a read request before restoring order execution.
The secret was not saved
Some exchanges show the secret and passphrase only once. If they cannot be retrieved, revoke that key and create a replacement rather than searching browser history, screenshots or logs for a copy. Store the replacement in the approved password manager or encrypted secret store before closing the creation flow.
The bot vendor demands every permission
Ask which endpoint requires each scope and whether the bot supports read-only setup, separate execution keys or IP restrictions. A vendor’s convenience is not a reason to grant transfer, withdrawal or Manage access. If the requirement cannot be narrowed and the workflow involves real funds, choose not to connect the account.
Decision checklist before you enable the bot
- Do I know every operation the bot will perform?
- Is the key dedicated to this bot and labeled with its purpose?
- Can I start with read-only access?
- Is Trade the only additional scope needed for order execution?
- Are Transfer, Withdrawal, Manage, margin and futures disabled unless explicitly required?
- Is the bot’s outbound IP stable and allowlisted?
- Are the key, secret and passphrase in encrypted or password-manager storage?
- Are account, API-key and bot-service 2FA protections enabled where available?
- Have I tested reads and the smallest practical order workflow?
- Do I know where to inspect, rotate and revoke this key?
No exchange source establishes a universal ranking of Binance, Coinbase Exchange and Kraken for API safety. Compare the controls that matter to your account: read versus trade scope, separate transfer permissions, IP allowlisting, 2FA, portfolio or product restrictions, and the ability to inspect, rotate and revoke keys. Then verify the exact settings in your own account, because labels and availability can change by region, key type and product.
