herramientas
check_job
Check Job Status

compress_file
Compress File to Exact Size (free)
Compress a file (PDF, JPG, PNG, WebP, MP4, MOV, WebM) down to an exact target size — e.g. "under 5MB for an upload form". FREE (daily limit applies). Returns a download URL on success; if the target is physically unreachable it fails honestly and reports the smallest achievable size. Provide EITHER source_url OR base64_content, plus a filename with extension.

Min 50KB.'}}}
convert_file
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).

Required.'}, 'base64_content': {'type': 'string', 'description': 'Base64-encoded file content (for small files; max ~5MB)'}}}
do_file_job
Do Something to a File (natural language)
Describe what you want done to a file in plain language — e.g. "translate this contract to German", "pull every table out of this PDF into Excel", "shrink this video to under 25MB", "convert this to PDF". The instruction is routed to the right job automatically; if the request is not supported yet you get an honest explanation of what is. Provide EITHER source_url OR base64_content, plus a filename with extension.

extract_tables
Extract Tables to Excel (paid, free preview)
Extract every table from a PDF or image (PNG, JPG, WebP) into a clean multi-sheet Excel file. The job runs immediately and returns a FREE preview of the first table plus a secure Stripe checkout link — the full .xlsx unlocks after payment ($3.99, one-time, no account needed). Provide EITHER source_url OR base64_content, plus a filename with extension.

List all supported conversion routes. Optionally filter by source format to see what you can convert FROM a specific format.

translate_file
Translate Document (paid, free preview)
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.
