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

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)
When configuring a custom model provider in most AI coding assistants, only three core pieces of information are needed: the Base URL, the API Key (placed in the Authorization Bearer header), and the Model ID (the model field).
After an API key leaks, it must be manually revoked and recreated in the service provider's console; access tokens can be invalidated immediately via a revocation endpoint.
API keys are usually long-lived static strings used to identify the caller and for billing, and many service providers do not support fine-grained scopes, whereas access tokens often have expiration times, scopes, and revocability.
After an API key leaks, merely creating a new key does not invalidate the old one, which remains valid on the provider side until it is explicitly revoked.
In the sandbox execution flow, the model provider's API Key and the sandbox management key must remain in the backend and must never be passed into the sandbox.
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.

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.

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.
