## Tools (as reported by the server, not verified)

- `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,
- `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
- `get\_entitlements`: Show the caller's current CleanChart tier. Anonymous callers are free tier \(watermarked, reduced resolution\). With an API key \(Authorization: Bearer cc\_..., created in the CleanChart dashboard\) this reflects the account's subscription or 24h day pass.
- `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
