# Agent Quickstart
> One prompt for your agent to set up and integrate Context.dev into your application
export const PromptBanner = ({prompt, message = "Use this pre-built prompt to get started faster."}) => {
const [copied, setCopied] = useState(false);
const timeoutRef = useRef(null);
useEffect(() => {
return () => {
if (timeoutRef.current) {
clearTimeout(timeoutRef.current);
}
};
}, []);
const handleCopy = useCallback(async () => {
try {
await navigator.clipboard.writeText(prompt);
setCopied(true);
if (timeoutRef.current) {
clearTimeout(timeoutRef.current);
}
timeoutRef.current = setTimeout(() => {
setCopied(false);
timeoutRef.current = null;
}, 2000);
} catch (err) {
console.error("Failed to copy:", err);
}
}, [prompt]);
const handleOpenInCursor = useCallback(() => {
const url = new URL('cursor://anysphere.cursor-deeplink/prompt');
url.searchParams.set('text', prompt);
window.location.href = url.toString();
}, [prompt]);
return
{message}
;
};
Get an API key, then paste the prompt below into your coding agent. It briefs the agent on every Context.dev endpoint, installs the MCP server and the skill, scans your repo for places Context.dev would help, and proposes project ideas tailored to you.
## Get your API key
Create an account at [context.dev/signup](https://context.dev/signup). The free tier gives you 500 one-time credits. No credit card required.
Open the [dashboard](https://context.dev/dashboard) and copy the key from the "API Keys" section. It starts with `ctxt_secret_`.
The SDKs, MCP server, and `curl` examples read `CONTEXT_DEV_API_KEY` from the environment:
```bash terminal theme={null}
export CONTEXT_DEV_API_KEY="ctxt_secret_..."
```
The official SDKs read `CONTEXT_DEV_API_KEY` first and fall back to `CONTEXT_API_KEY` if it isn't set, so exporting `CONTEXT_DEV_API_KEY` alone is enough. It's also the doc standard and what the MCP server and `curl` examples use.
Never call the Context.dev API directly from a browser. The key would be visible to anyone with devtools. Always proxy through your backend.
## Copy the prompt
Run your agent in the directory where your application code is located and paste this prompt:
