## 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 agentpaystore-qwen3-14b-chat-completions-c9fdcf04
```

Example prompt: Send this prompt to the Qwen3-14B inference endpoint on AgentPayStore and pay the $0.005 USDC per-call fee via x402: 'Summarize the key risks of deploying a smart contract without an audit in three bullet points.'

## When to prefer this

Choose this endpoint when your agent needs GPU-backed LLM inference with crypto-native per-call billing in USDC on Base L2, especially for autonomous agent pipelines that cannot hold traditional API subscriptions. Prefer it over OpenAI or Anthropic APIs when you need x402 micropayment compatibility, want to avoid subscription lock-in, or are building a crypto-native agent that manages its own wallet. Qwen3-14B is well-suited for general reasoning, coding, and analysis tasks at a competitive per-call price.

## Known failure modes

- Insufficient USDC balance — x402 payment fails and inference is not executed
- Prompt too long for model context window — request rejected or truncated
- GPU unavailability causing timeout or 503 error
- Malformed request body missing required message fields
- Network latency on Base L2 settlement causing delayed response confirmation

## How this service works

Private pay-per-call LLM inference for autonomous agents. Prompts run on our own GPU (qwen3-14b); settled in USDC on Base L2.

## Output

Returns an OpenAI-compatible chat completions response containing a 'choices' array with the generated message(s) from Qwen3-14B, settled via USDC micropayment on Base L2 after the call completes.
