`apply_data_fixes`Clean tabular data with CleanChart's fix engine and get the cleaned rows back plus a change log. Options (all optional booleans unless noted): remove_duplicates, remove_empty_rows, remove_empty_columns, trim_whitespace, replace_invalid_values (turn N/A/-/? into null), nullify_missing, convert_types, missing_strategy ('fill_smart' fills gaps with column mean or 'Unknown'), date_standardization with date_columns (string[], converts recognized date formats to YYYY-MM-DD), strip_numeric_formatting with format_columns (string[]), strip_coded_values with coded_columns (string[]).

`create_checkout`Create a payment link the USER must open in their browser — never call this without the user explicitly asking to purchase. kind 'day_pass' (the Deadline Pass: 7 days of unlimited clean exports) or 'subscription' (Pro: monthly unlimited). Both are account-based: after payment CleanChart emails a sign-in link, and an API key from the dashboard unlocks clean renders over MCP.

`detect_data_issues`Analyze tabular data for quality issues before charting: duplicates, missing values, whitespace, invalid tokens (N/A, -, ?), type mismatches, outliers, inconsistent date formats, and per-column inferred types. Returns a report whose findings map directly to apply_data_fixes options.

`generate_chart`Render a publication-ready chart from tabular data and return it as a PNG image. By default the image is only delivered inline and never stored — in chat UIs the user can save it straight from the conversation. If the user needs a downloadable file (e.g. your client cannot save inline images), pass returnUrl:true: the response then also includes chartUrl, a direct link to the PNG valid for 24 hours — surface it to the user. Without an API key the free tier applies: watermark and reduced resolution — mention the upgrade info from the response to the user if they want a clean export (create_checkout provides a payment link). With a CleanChart API key (Authorization: Bearer cc_...) and an active subscription or 24h day pass, output is clean and full resolution. Call validate_chart_config first; large datasets are sampled automatically.	Render a publication-ready chart from tabular data and return it as a PNG image.
