API examples completeness

Ensure all API code examples include all required parameters with correct placeholder values. Incomplete examples lead to user confusion and implementation errors when developers copy-paste documentation snippets.

When documenting API usage, always include:

• All required parameters, not just the most obvious ones
• Correct placeholder formats (e.g., use <<REPLACE WITH YOUR API KEY>> for keys, not URLs)
• Clear distinction between different parameter types (URLs vs keys vs other values)

Example of complete API documentation:

elements = partition_via_api(
    filename=filename,
    api_key="<<REPLACE WITH YOUR API KEY>>",
    api_url="https://<<REPLACE WITH YOUR API URL>>/general/v0/general"
)

Rather than incomplete examples missing the api_key parameter or using incorrect placeholder values. Consider providing separate examples for different usage scenarios (SaaS vs self-hosted) when the parameter requirements differ significantly.
