How this service works
OpenAI-compatible chat completions on OpenAI gpt-oss-20b open-weight reasoning model with tool calling. Set your OpenAI SDK base URL to https://agents.torbrooknews.com/v1/gpt-oss-20b and pay $0.003 per request with x402 instead of an API key. Same request/response shape as OpenAI (tool calling, reasoning, streaming supported), up to 4096 output tokens. Also callable as GET with the same fields as query parameters.
Output
Returns an OpenAI-compatible chat completion object containing the assistant's message, optional tool call specifications, reasoning traces, and token usage counts — identical in shape to the OpenAI API response, up to 4096 output tokens.
Example use cases
Keyless LLM for agentic pipeline
“I need to call a reasoning-capable LLM in my agent without setting up an OpenAI API key — send the prompt 'Summarize the pros and cons of microservices architecture' to gpt-oss-20b with a system message saying 'You are a senior software architect' and max 512 tokens.”
Tool-calling step in automation
“Use the gpt-oss-20b model to decide which tool to call next given this context: 'The user wants to check the weather in Paris tomorrow' — enable tool calling and keep temperature at 0.”
Quick reasoning answer on demand
“Ask the open-weight reasoning model: 'A train leaves at 9am going 80mph and another at 10am going 100mph from the same station — when does the second train catch up?' and give me the step-by-step answer, up to 256 tokens.”
