Pinned tool definitions (27)
| Tool | Description |
|---|---|
| signup | Creates a workspace and returns its API key (shown ONCE — keep it). Works on a keyless connection; every other tool needs the key. Then put the key where your client keeps it (plugin api_key setting, the Authorization header, or... |
| whoami | Returns key name + workspace. Call this first — non-destructive auth check. Everything you write is stamped createdBy/updatedBy = key name. |
| list_asset_types | Chart/table types you can create, with links to per-type schemas. |
| get_spec_schema | Returns the JSON Schema for the type's config, the data schema, two worked examples (minimal + rich), and `defaults` — the complete config in force when nothing is set (every font, padding, color), which a brand and then the chart's own... |
| list_assets | Filterable list; rows elide config/data. Use get_asset for full bodies. |
| get_asset | Full asset envelope. includePreview=true also returns an inline PNG of the current draft. |
| list_geographies | countries, us-states, us-states-pr (with Puerto Rico), us-counties, us-zip3, us-zips-<st> (one state's ZIP codes), and every country's states/provinces as <alpha-2>-regions (de-regions, ru-regions…). Pass id to get one geography's full... |
| list_templates | Templates are named by the NEED they answer (need, asks, tags), each with urls.png (show it to your human) and `columns`: the column ids your data must supply. Pass q with what the person asked for — "map of brazil's states", "ranked... |
| create_asset | Creates a draft. The response includes a low-res PNG preview INLINE — look at it, then iterate with update_asset. Nothing is public until publish_asset, or until you pass publish: true here (one call instead of two, once the chart is... |
| update_asset | configPatch is DEEP-MERGED: objects merge recursively, arrays replace wholesale, null clears a key — send only what changes. To REMOVE keys (drop document.aspect, delete one of texts[]) pass `config` instead: it REPLACES the whole... |
| replace_asset_data | THE core flow for refreshing numbers. publish defaults to auto: a published asset republishes immediately (every embed/PNG updates); a draft stays draft. Set publish=false to stage instead. LIMITS: an asset holds up to 2 MB of data, but... |
| set_data_source | The chart refetches this URL (CSV or JSON) hourly/daily/weekly, replaces its rows, and republishes itself if published — refreshes are free, updates are never metered. Columns stay as defined on the asset: CSV headers / JSON object keys... |
| clear_data_source | Stops scheduled fetches; the chart keeps its current data. |
| fetch_data_source | Runs one fetch on top of the schedule. Returns {ok, rows, published, error}. |
| publish_asset | Makes the draft live. Returns urls: paste urls.embedIframe on iframe platforms; on Substack insert urls.png as an image and link it to urls.page. Pinned history: urls.png + '?v=N'. |
| unpublish_asset | Embeds and PNGs return 410 until republished. |
| duplicate_asset | New id, new embed URLs. Useful for rebranding a chart for another audience. |
| delete_asset | Embeds go dark. Restorable via the REST API (POST /api/assets/{id}/restore). |
| list_brands | Style-only token sets applied under your config. Pass a slug as `brand` on create_asset. |
| create_brand | A brand styles every asset that references it — and the workspace default brand styles everything created without an explicit brand. Create one, then render any asset with brand: "<slug>" to see it applied. Style only: brands can never... |
| update_brand | Deep-merges tokens (objects merge, arrays replace, null clears). Drafts restyle immediately; published assets pick the change up on their next publish. Requires expectedVersion from list_brands. |
| get_billing | Hosting is free (unlimited badged charts, live updates included). One credit makes one chart premium forever: 2400px, SVG, your own branding, no badge. Updates are never metered. |
| create_checkout_link | Returns a URL that opens straight into Paddle checkout: no login, no account. It can only add credits to THIS workspace, so it is safe to share. Credits arrive seconds after payment (get_billing). |
| upgrade_to_premium | Same URLs, instantly rebranded: badge removed, 2400px PNG and SVG unlocked, custom branding applies. Idempotent for already-premium charts. |
| create_edit_link | Returns a URL opening the visual tweak panel for ONE chart (text, colors, spacing, label nudges) with no login. PUBLISH FIRST: the editor saves and republishes a published chart, it cannot publish a draft. Scope: view, tweak, and... |
| revoke_edit_link | The URL stops working immediately. List links (prefixes + tokenIds) via GET /assets/{id}/edit-links. |
| submit_feedback | If a capability is missing, a schema fights you, or docs are wrong: record it here so the owner can fix it. One report per distinct issue, with a real description — reports get fixed same-day when they say what you tried, what you... |
