list_chart_types | List all chart types CleanChart can render, each with its default config object. Use a default config as the starting point, override what you need (title, xColumn, yColumn, colors, ...), then call validate_chart_config before generate_chart. |
validate_chart_config | Dry-run validation of a chart config for a given chart type. Returns valid:true or a list of human-readable problems to fix. Always call this before generate_chart — it is free and instant, while a failed render costs a rate-limited attempt. |
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. |
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, |

create_checkout | Create a payment link the USER must open in their browser — never call this without the user explicitly asking to purchase. kind 'single_chart' (pass the exact data, chartType, and config to be rendered; after payment call claim_chart to receive the clean chart), 'day_pass' (24h unlimited clean expo |
claim_chart | Redeem a paid single-chart purchase (from create_checkout with kind 'single_chart') and receive the clean, full-resolution PNG. Call this after the user confirms payment. Returns payment_pending while the checkout is unpaid — wait for the user, do not poll in a loop. By default the image is only del |
