🌿 Fern Regeneration -- April 8, 2026

[fern-api]

This PR regenerates code to match the latest API Definition.

---

Note

Medium Risk
Introduces potentially breaking SDK surface changes by making api_key required (and raising ApiError when missing) and by changing knowledge_base.documents.get_content to return text instead of None. Remaining changes are largely auto-generated doc/example churn and version bumps.

Overview
Regenerates the Fern-produced Python SDK and bumps the package version to 2.42.1 (Fern CLI metadata updated, including originGitCommit).

Behavioral/API changes: ElevenLabs/AsyncElevenLabs now require api_key at construction time and raise ApiError if it’s missing, and conversational_ai.knowledge_base.documents.get_content (sync/async + raw clients) now returns the document content as str (using _response.text) instead of returning None.

Large amounts of auto-generated documentation/examples were updated (notably many snippets now show a duplicated api_key argument, and the studio.create_podcast example drops safety_identifier).

Duplicate keyword argument in all code examples

High Severity

Every code example in the SDK now contains a duplicate api_key="YOUR_API_KEY" keyword argument. In Python, duplicate keyword arguments are a SyntaxError. Users copying any example from reference.md or the docstrings will get an immediate syntax error. This affects hundreds of examples across the entire codebase.

Error message references wrong environment variable name

Medium Severity

The error message tells users to set ELEVEN_API_KEY, but client.py actually reads from ELEVENLABS_API_KEY via os.getenv("ELEVENLABS_API_KEY"). Users following the error guidance would set the wrong environment variable and still fail to initialize the client.
