The delta and sparkline are computed for you. 3 ### Get a card image back The response is a finished KPI card with a permanent URL, ready to drop into a Slack message, an email, or a status page. ## What people render ### Slack & email KPI digests A daily or weekly card of your north-star metrics, posted automatically to a channel or newsletter. ### Report & investor-update cards Turn the top-line numbers of a report into a clean, on-brand image people actually read. ### Status & health pages Render uptime, latency, or usage tiles as images that embed anywhere. No dashboard iframe required. ### Metrics in email Email strips scripts and canvas, so live dashboards break. A KPI image renders for every recipient. ### Embedded customer metrics Show each user their own numbers in-product or in lifecycle emails, generated per account. ### Automated reporting Wire it to your warehouse or analytics and generate a fresh KPI card on every run. ## Why an image, not a dashboard embed? ### Dashboard iframes / embeds Need a live browser, break in email, and leak access to your whole dashboard. A single static image URL, safe to send anywhere, renders instantly. ### Screenshotting a dashboard Run and scale headless Chromium, fight layout drift and cold starts for one tile. Send the numbers, get the exact card back. Nothing to host. ### Hand-built image templates Recompute deltas and draw sparklines yourself in code, per metric. The metric component does deltas and sparklines from raw values. ## Keep exploring [Chart Image API (all chart types)](/chart-image-api)[The metric component](/components/metric)[All 24 chart & data components](/components)[Free chart maker tools](/tools) ## KPI Card Image API FAQs ### What is a KPI card image API? It renders a KPI or metric card, a value with a delta and often a sparkline, as a static image (PNG or SVG) from numbers you send over HTTP. You use it when the metric has to appear somewhere a live dashboard can't: an email, a Slack message, a PDF, or a status page. ### Can it show a delta and a sparkline? Yes. The metric component renders the value, a change/delta versus a previous value, and a sparkline from a series you pass in, so you only send raw numbers, not pre-drawn graphics. ### Can I build a full dashboard card? Yes. Combine multiple metric tiles with tables, charts, progress bars, and radar components on one template to render a complete dashboard-style card as a single image. ### Does it work in email and Slack? Yes, that's the point. Email and chat apps strip scripts and canvas, so a live dashboard won't render. A KPI card image works everywhere an or an image URL does. ### Is there a free tier? Yes. 100 renders per month, permanently, with no watermark. Paid plans start at $14.99/mo for 1,000 renders and scale to a $0.70 effective cost per 1,000 on the Unlimited plan. ## Render your first KPI card in minutes Start on the free tier. 100 renders a month, no watermark, no card.
