Is there an official regex to prevalidate OpenAI API Keys and Organization IDs?

Below is a summary of what’s currently known regarding this topic:

1. No Official Regular Expressions:
   The OpenAI API documentation does not provide or endorse any official regular expressions for validating the formats of API keys or organization IDs. Any patterns you might infer (such as checking for expected prefixes) are based on general observations and not on officially documented formats.

2. Common Observations:

   • API Keys: Many API keys (particularly secret keys) start with a prefix (like "sk-"), but the exact string length and allowed characters are not formally specified.
   • Organization IDs: Similarly, organization IDs often start with a prefix (such as "org-"), but again, there’s no officially provided regex pattern to validate their complete format.

3. Best Practices:
   Instead of relying on pre-validation with regex patterns—which may not fully capture valid values and could produce false negatives—it's generally recommended to make a backend API call for authentication. This not only confirms that the credentials are correct but also maintains best practices for security by managing secret keys properly.

Here’s an example of what a simple client-side check might look like; however, please note these are only informal checks and not officially guided:

JAVASCRIPTCopied
// Example pre-validation (informal, not official)
function isLikelyValidApiKey(apiKey) {
  // API keys often start with "sk-" and have a length check, but this is not official.
  return typeof apiKey === 'string' && apiKey.startsWith('sk-') && apiKey.length > 20;
}

function isLikelyValidOrgId(orgId) {
  // Organization IDs often start with "org-" and have a length check, but this is not official.
  return typeof orgId === 'string' && orgId.startsWith('org-') && orgId.length > 10;
}

// Usage:
const apiKey = 'sk-exampleapikey...';
const orgId = 'org-exampleid...';

if (isLikelyValidApiKey(apiKey) && isLikelyValidOrgId(orgId)) {
  // Proceed with the API call
} else {
  // Handle pre-validation failure
}

Remember, these checks are just heuristics. The definitive validation should always be performed by the API through an authentication attempt.
