GETTING STARTED
A live agent in five minutes
Five steps, start to finish. Everything is free during beta, no card required. By the end you will have a working assistant embedded in your product that can read your docs and call your tools.
Steps
1
Create a project
Sign in to the console at /admin and create a project. Each project has its own agent, its own key, and its own settings. Copy the project key, it looks like
era_... and goes in the widget snippet below.2
Add a model provider key
Open Settings and paste a key from Anthropic, OpenAI, or Google (Gemini). EERRAA never charges you for LLM tokens, you pay your provider directly. Keys are encrypted at rest, tried in priority order, and health-checked. Add more than one for automatic failover.
3
Paste the embed snippet
Drop this one script tag into your product's HTML, just before the closing
</body>. Swap in your real project key. The widget is vanilla JS with zero dependencies and renders in a Shadow DOM, so it will not collide with your styles.html
<script src="https://eerraa.online/static/widget.js" data-api-key="era_your_project_key" data-title="Assistant" data-primary-color="#19c37d" data-placeholder="Ask me anything…" data-position="bottom-right" ></script>
4
Set your allowed origins
Back in Settings, add the domains your product runs on to the allowed origins list. A request from a domain that is not listed is refused with
ORIGIN_NOT_ALLOWED. Add localhost while you develop, then your production domain when you ship.5
Say hi
Load the page. The launcher appears in the corner. Open it and ask a question. You will see the agent stream its answer, show live tool status as it works, and ask for approval before any write action. That is the whole loop.
A working model key is required. With no healthy key, chat is rejected with
PROJECT_NO_API_KEY. Add at least one provider key in step 2 before you test.Where to next
You have an agent that talks. Now make it act. Read the core concepts to see how identity, tools, and knowledge fit together, then follow the Connect tools guide to give it actions, or upload your docs so it answers from your own content.
