Frequently asked questions
Can I capture only a specific part of a webpage?
Yes! Use the render_selector tool. Provide the URL and the CSS selector (e.g., #my-chart) to capture only that specific element instead of the whole page.
How do I see how many credits I have left?
Run the get_credit_usage query. Your agent will retrieve your current credit balance and monthly rendering metrics directly from Urlbox.
Can this tool convert a URL directly to PDF?
Absolutely. Use the capture_pdf tool by providing the URL. You can also specify an optional page size like 'A4' or 'Letter'.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
