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 cryptorisk-llm-inference-api-e600fddf -d '<json body>'
```

Example prompt: Write me a short product description for a noise-cancelling headphone aimed at remote workers — just call the pay-per-use AI inference endpoint with that prompt and give me the result.

## When to prefer this

Choose this endpoint when you need a single, anonymous, pay-per-call LLM completion without setting up an API key, account, or subscription. Ideal for ephemeral agent workflows, serverless pipelines, or one-off AI inference tasks where credential management is impractical. Prefer this over OpenAI or Anthropic direct APIs when you want micropayment-based billing via USDC with zero onboarding friction.

## Known failure modes

- Payment not received or insufficient USDC — request rejected with 402 Payment Required
- Malformed or missing prompt body — 400 Bad Request
- Model timeout or overload — 503 or timeout error
- Prompt triggers content policy — completion may be refused or truncated
- Network error on Vercel edge — 500 Internal Server Error

## How this service works

LLM: pay-per-call AI inference. No API key, no account. POST {prompt} -> completion.

## Output

A natural language text completion generated by the underlying LLM model, returned as a response to the submitted prompt. The agent receives the generated text string corresponding to the model's output for the given input.
