- ✓Plain JSON, no SDK
- ✓Omit doc → sample render
- 3
POST and get a PNG
One request with your key. Phone screens render at a fixed frame; posts and AI conversations come back auto-cropped tight to the content — identical to the browser download.
- ✓image/png response
- ✓2× pixel density by default
- ✓Headless — no browser needed
Built for agents, automation & scale
The browser version is for one screenshot by hand. The API is for a thousand, or for an agent that makes its own.
AI agents & chatbots
Expose POST /api/screenshot as a tool with your key in the Authorization header and let an assistant render a fake chat inline — one HTTP call, JSON in, PNG out.
See the request →Automation & no-code
Call it from n8n, Make, Zapier or a cron job to turn rows of text into a batch of social mockups. Fully headless, no browser to babysit.
See the request →Content at scale
Generate hundreds of variations for ads, memes, demos or QA fixtures from a script — every one pixel-identical to the in-app export. Go unlimited on Pro.

Frequently asked questions
Is there a free tier?+
Yes. Every account gets 30 API requests per month for free, plus unlimited manual image generation on the website. Need more? Pro gives unlimited API requests and video generation ($6.90/month or $50/year), and Creator is a $100 lifetime plan. See the pricing page for details.
Do I need an API key?+
Yes, and a free one takes seconds: sign in with your email, open your account, create a key (it's shown once), and send it as an Authorization: Bearer header. The same key works from your code, automation tools and AI agents.
What can I generate?+
26 generators across chats (WhatsApp, iMessage, Telegram, Instagram DM, Discord, Tinder), social posts (X/Twitter, Facebook, Instagram, LinkedIn, TikTok, Threads, Bluesky, Pinterest) and AI conversations (ChatGPT, Claude, Gemini, Grok, Perplexity). GET /api/screenshot returns every supported slug.
How do I use it with ChatGPT, Claude or another agent?+
Any agent or tool framework that can make an HTTP request can call it. Register POST /api/screenshot as a tool, put your key in the Authorization header — JSON in, PNG out — and the agent can produce screenshots mid-conversation. There's also an MCP server that wraps the same endpoint.
What shape is the doc field?+
doc is exactly the content the in-app editor produces — messages, contact, post, model, and so on, depending on the generator. Send a request with no doc and the API renders that generator's sample so you can mirror the structure.
Do you store the content I send?+
No. The chat content in your request is rendered and discarded — we don't keep it. We record only anonymous usage counters (which generator, when, render time) to run the service and meter quota; the messages, names and images you send are never stored.
What format and size is the output?+
A PNG at 2× pixel density by default (set scale 1–3). Phone generators render at a fixed 375×812 frame (750×1624 at 2×); posts and AI conversations are auto-cropped tight to their content, exactly like the browser download.
