convert_file
Convert a file from one format to another. Anonymous callers get 25 free conversions per month per network; after that a free verified ChangeThisFile API key is required (25/month shared across REST + MCP; send it as Authorization: Bearer ctf_sk_…). Pass EITHER a publicly accessible URL (source_url) OR base64-encoded file contents (base64_content + source_format) — exactly one is required. Returns a temporary download URL (valid 1 hour; file deleted within 24 hours).
list_conversions
List all supported conversion routes. Optionally filter by source format to see what you can convert FROM a specific format.
translate_file
Translate a document into another language with the original layout and formatting preserved (DOCX, PPTX, XLSX, PDF, TXT, MD, SRT, VTT). The job runs immediately and returns a FREE preview of the first pages plus a secure Stripe checkout link — the full translated file unlocks after payment ($4.99, one-time, no account needed). Provide EITHER source_url OR base64_content, plus a filename with extension.
