API Key
An access credential for AI services based on an HTTP request header authentication mechanism. It is attached to the Authorization field to verify request legitimacy and associated account quotas.
Core Facts
DeepSeek API Key创建后只显示一次，之后无法再查看
Storing API keys as environment variables rather than hardcoding them in the source code is a security best practice.
Once an API Key is leaked, an attacker can make unlimited API calls from anywhere in the world as the key holder, and the server cannot distinguish legitimate calls from unauthorized ones.
Timeline (last 90 days)
If an API Key is written directly into front-end code, any visitor can see it through the browser developer tools, creating a risk of it being stolen and abused, so it should be moved to the server side before official launch.
An API Key has account operation permissions, should not be committed to a code repository, and is recommended to be managed uniformly through an environment variable file.
In traditional architectures the Agent holds an API Key and can spend as much as it wants, in stark contrast to the budget envelope mechanism.
If all requests share a single API key with no unified call gateway or tagging mechanism, the bill cannot be attributed to specific business units.
An API Key is usually displayed in full only once upon creation, so it must be saved promptly.
Common technical implementation paths for such gray-market products include sharing enterprise accounts or team seats, reselling API Keys in violation of terms, or building relay layers before official bans take effect.
An API Key is a stateless access token; the server only verifies whether the Key is valid and does not associate it with geographic location, device fingerprints, or other behavioral data, so it less frequently triggers risk controls such as logins from unusual locations.
Major platforms all provide usage caps and anomaly alerting features, and it is recommended that developers configure these as soon as an API Key is created.
An API key is a simpler static credential solution suited for service-to-service calls, but lacks fine-grained permission control and automatic expiration mechanisms.
Neither OAuth tokens nor API keys are suitable for long-term storage by being written directly into configuration files, because if leaked, attackers can immediately impersonate the identity to access resources.

70%VerifiedThe API services of companies such as OpenAI and Anthropic use an API Key-based authentication mechanism, where each key is bound to a specific account and subject to rate limit constraints.
70%VerifiedAPI keys should not be hard-coded in source code and pushed to public code repositories such as GitHub.
70%VerifiedWorkBuddy has a built-in connector mechanism that interfaces with the data layer of target software via API authorization (OAuth protocol)—for example, reading messages and sending replies through the WeCom open platform API—rather than simulating screen clicks.
65%VerifiedDeepSeek API keys are hidden after creation and must be copied and saved immediately upon generation.
65%VerifiedIn BYOK mode, API keys are stored in plaintext in local configuration files, posing a security risk of key leakage
65%VerifiedOnce an API Key is leaked, others can charge expenses to your account; never hard-code it and commit it to a public code repository.

85%UnverifiedAPI Keys are designed with no concept of expiration and remain valid long-term once generated; whereas tokens have an expiration time and require re-login to obtain after expiry.
60%UnverifiedAn API Key is a string credential used for identity verification when calling AI services; it is attached to the request header with each request, allowing the server to identify the caller's identity and calculate usage and fees accordingly.
