How this service works

Ultra-fast LLM inference — Llama 3.3, DeepSeek R1, Gemma 2, GPT-OSS, Qwen, Whisper, and PlayAI TTS. OpenAI-compatible API with industry-leading speed.

Output

Returns a JSON object with a 'data' field containing the OpenAI-compatible chat completion (including the assistant message, finish reason, and usage stats), a 'payment' object showing settled and authorized USDC amounts, a 'request' object with a UUID and status URL, and a 'success' boolean.

Example use cases

Real-time agent reasoning loop

“I need you to run this multi-turn conversation through Llama 3.3 on Groq — it's time-sensitive, so I need the fastest inference possible. Here are the messages: [{"role":"system","content":"You are a helpful assistant."},{"role":"user","content":"What are three key risks in launching a SaaS product?"}]. Use temperature 0.5 and cap the output at 300 tokens.”

Structured JSON extraction from text

“Send this prompt to GPT-OSS 20B on Groq and tell it to return a JSON object with fields 'name', 'date', and 'amount' extracted from the text: 'Invoice from Acme Corp dated March 14 2025 for $4,200.' Set response_format to json_object and max tokens to 200.”

DeepSeek R1 multi-step reasoning with trace

“I want to use DeepSeek R1 on Groq to solve this logic puzzle step by step: 'If all Bloops are Razzies and all Razzies are Lazzies, are all Bloops definitely Lazzies?' Return the full reasoning trace in raw format with max 1024 completion tokens.”

Endpoint

When to prefer

Choose this endpoint when you need the lowest-latency LLM inference available (Groq is industry-leading for tokens/sec), want OpenAI-compatible chat completions without a monthly subscription, need to pay per-call in USDC via x402 micropayments, or want access to open-source frontier models like Llama 3.3, GPT-OSS 120B, Qwen, or DeepSeek R1 without managing API keys. Prefer over standard OpenAI when speed is critical or when your agent runtime uses x402 payment rails.

Side effects

Insufficient USDC authorization — x402 payment header missing or amount below required $0.005
max_completion_tokens not specified — required by x402 to set a hard ceiling on the signed authorization
Invalid model ID — model not available on this public metered endpoint
Messages array empty or malformed — API returns 400 bad request
Token limit exceeded — response truncated or error if max_completion_tokens too low for the task
Rate limiting — Groq upstream throttle returns 429
Network timeout — real-time inference request exceeds gateway timeout
