API Key
A unique identifier string used for authentication and access control. Clients must include the correct key in requests to access protected API interfaces.
Core Facts
Timeline (last 90 days)
API keys and personal access tokens are often hardcoded in scripts or configuration.
Unlike user passwords, API keys and service tokens usually have no bound natural-person identity and lack expiration mechanisms, so once left behind they can remain valid for a long time.
API keys and service tokens are often overlooked when employees change positions, because their ownership is recorded in application configurations or key management systems rather than in HR or directory services.
The scope of permission removal should cover application-layer permissions, system accounts, shared resource access, and any API keys or service tokens that may exist.
The attack occurred at night, and intruders used API keys stored in Console to call the APIs of major AI providers, incurring unauthorized charges, with some developers' bills ranging from hundreds to thousands of dollars.
Revoking an API key does not mean that a third-party model or platform vendor has deleted the related data.
Only the provider can fully revoke (disable) an API key.
Key deletion and revocation have different semantics: deletion usually only removes the stored record or reference on the platform side, while the key remains active at the provider; revocation marks the key as invalid in the provider's control plane.
A provider API key is a bearer credential, and anyone holding a copy can run billable requests on the owner's account until the provider revokes the key.
A stored API key is equivalent to cash: once leaked it causes losses, and the speed of loss depends on call frequency.

Modern AI programming tools generally use API keys or OAuth tokens as access credentials, which are attached to the Authorization field of HTTP request headers.

50%UnverifiedOn Synmerco, agents obtain identity by registering a DID (wallet address) and an API key, and interact via HTTP with a Bearer token.
50%UnverifiedXisu AI allows creating multiple API keys and assigning an independent budget cap to each key; one key reaching its limit does not affect other keys, and keys can be revoked at any time with changes taking effect immediately.
50%UnverifiedAny API key appearing in a public repository or frontend bundle should be rotated and constrained using the provider's referrer or IP restrictions.
50%UnverifiedIt is recommended to allocate a separate API key for each Agent, so that billing is separated, limits are separated, and shutting one down does not affect the others.
50%UnverifiedAgent projects usually involve external dependencies such as API keys, model access permissions, vector databases, and tool interfaces, and missing any one of them may cause the code to fail to run.
50%UnverifiedAPI keys must stay on the server side, not be exposed in front-end JavaScript, and not be committed to public repositories.
50%UnverifiedAPI keys and tokens carry almost no information about what the Agent was asked to do, who assigned it, or how the task reached the Agent, resulting in permissions that are static and pre-configured while tasks are dynamic and contextual.
50%UnverifiedSince the tool transmits over plaintext HTTP, the API key can be sniffed on the same subnet, so it is more suitable for preventing misuse than for preventing attacks.
50%UnverifiedEach time the tool starts, it automatically generates a 35-digit API key, and other devices must enter the correct key to call it.
