# OpenAI API key (`openai_api_key`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Secret key of the OpenAI API. Keys start with sk-; project, service account and admin keys start with sk-proj-, sk-svcacct- or sk-admin-. Secret scanners recognise them by the fixed marker T3BlbkFJ in the middle of the key. Examples are left out because GitHub push protection rejects token-shaped values, even constructed ones.

- Parent datatype: `api_key`
- Personal data (PII): no
- Categories: Secrets and credentials (passwords, keys, tokens) (secrets)
- Countries: global

## Detection

Regular expression (Python `re`):

```
^(?:sk-(?:proj|svcacct|admin)-(?:[A-Za-z0-9_-]{74}|[A-Za-z0-9_-]{58})T3BlbkFJ(?:[A-Za-z0-9_-]{74}|[A-Za-z0-9_-]{58})|sk-[A-Za-z0-9]{20}T3BlbkFJ[A-Za-z0-9]{20})$
```

## Examples
