# Groq via Locus x402 — LLM Inference & Audio

> Groq via Locus x402 — LLM Inference & Audio is a paid API for AI agents from groq.x402.paywithlocus.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Proxies requests to Groq's ultra-fast inference API (Llama 3.3, DeepSeek R1, Gemma 2, Qwen, Whisper, PlayAI TTS) with per-call USDC micropayment via x402 protocol

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability groq-via-locus-x402-llm-inference-audio-1e52a424 -d '<json body>'
```

Example prompt: Using Groq's ultra-fast inference, send a chat completion request to Llama 3.3 asking it to summarize the following paragraph in three bullet points: 'Artificial intelligence is transforming industries by automating complex tasks, enabling faster decision-making, and unlocking new capabilities in fields ranging from healthcare to finance.'

## When to prefer this

Choose this endpoint when you need ultra-low-latency LLM inference (Groq is industry-leading for speed), want to pay per-call in USDC via x402 without a subscription, need an OpenAI-compatible API surface, or require access to open-weight models like Llama 3.3, DeepSeek R1, Gemma 2, or Qwen alongside audio capabilities (Whisper STT, PlayAI TTS) in a single gateway. Prefer over standard Groq API when operating in a crypto-native or agent-payment context.

## Known failure modes

- Insufficient USDC balance or payment failure — 402 Payment Required with payment details
- Invalid or unsupported model name — 400 Bad Request or Groq API error forwarded
- Malformed request body or missing required fields — 422 Unprocessable Entity
- Groq upstream rate limit or outage — 502/503 from the proxy
- Audio file format not supported by Whisper — error from underlying Groq endpoint
- Request timeout for very long inference tasks

## How this service works

Locus public pay-per-use API

## Output

Returns a JSON response containing the Groq API output (e.g. chat completion text, token counts, transcription text, or audio data), a payment object confirming the settled USDC amount and authorized max, a request ID with a status URL for async tracking, and a success flag.
