Stock Chart Image API

Stock & candlestick charts as images

Render candlestick (OHLC), line, and combo charts as PNG or SVG from a single endpoint. Drop live price charts into alerts, trading digests, and bots that can't run JavaScript.

Built for financial data

Candlestick is a first-class component. Pair it with metric tiles, tables, and line charts to render full market cards. These are live previews.

From data to image in one call

1

Design a chart template

Style a candlestick or line chart in the editor once: colors, axes, branding. Then mark the OHLC series dynamic.

2

Send your price data

POST your OHLC/series data as field overrides on each request. No config JSON to hand-write, no webhook to wait on.

3

Get a chart image back

The response is a finished image with a permanent URL, ready for an email, a Telegram/Discord bot, or a Slack alert.

What people render

Price & threshold alerts

Attach a candlestick snapshot to a price alert so the recipient sees the move, not just a number.

Crypto market recaps

Daily BTC/ETH or altcoin charts for a newsletter, Discord, or Telegram channel, as an image everyone can see.

Trading & signal bots

Bots live in chat apps that strip scripts and canvas. An image URL renders the chart everywhere.

Market digests

A morning email with the indices, top movers, and a chart per ticker, generated from your feed.

Portfolio & position cards

Combine a candlestick with metric tiles and a positions table into one shareable portfolio card.

Automated reporting

Wire it to your market data source and generate a chart image per symbol, per run. Hands-off.

Why not roll your own?

Headless-browser screenshots

Run Chromium + a charting lib, install fonts, fight cold starts just to screenshot a candlestick.

One sync endpoint. Send OHLC data, get an image. Nothing to host.

Config-driven chart APIs

Hand-write chart JSON and accept generic defaults that look like everyone else's.

A visual editor and on-brand templates, then the same chart on tap via API.

Client-side charting libraries

Great in a browser. Useless in an email, a bot message, or a PDF where JS never runs.

A static image URL works in every one of those places.

Stock Chart Image API FAQs

What is a stock chart image API?

It renders a stock or financial chart as a static image (PNG or SVG) from price data you send over HTTP, so the chart can live where JavaScript can't run: an email, a bot message, a PDF, or an OG tag.

Do you support candlestick and OHLC charts?

Yes. Candlestick (OHLC) is a first-class component, alongside line, area, and combo charts, so you can render price and market-recap graphics from a single API call.

Can I use it for crypto charts?

Yes. The data is just OHLC/series values, so it works for any market: equities, forex, or crypto. Send your data and get a branded chart image back.

Is the chart real-time?

The API renders fresh on every request from the data you send, so it's as current as your data feed. There's no caching you don't control and no polling.

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.
