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 zeroreader-mistral-7b-chat-completion-9fa38de8 -d '<json body>'
```

Example prompt: Send this to Mistral 7B via ZeroReader: system prompt 'You are a helpful assistant that outputs only valid JSON', user message 'Extract the name, date, and amount from this invoice text: Invoice #1042, John Smith, 2024-06-01, $450.00', max 512 tokens, temperature 0.2.

## When to prefer this

Choose this endpoint when you need a fast, cost-effective, European open-source LLM with strong structured output capabilities (JSON, markdown, etc.), especially when compliance with EU AI regulations matters or when GPT-class quality is not required. Prefer over larger models when latency and cost are priorities, and over proprietary APIs when open-source provenance is important.

## Known failure modes

- Payment failure or insufficient USDC balance returns 402
- Prompt exceeds max_tokens limit causing truncation or error
- Temperature or max_tokens out of allowed range returns 400 validation error
- Model unavailable or overloaded returns 503
- Malformed messages array (missing role or content) returns 400
- Streaming not supported in certain client configurations

## How this service works

Mistral 7B — European open-source model. Good at structured output.

## Output

Returns an OpenAI-compatible chat completion object with an id, object type 'chat.completion', a choices array containing the assistant's generated message, and a finish_reason (e.g. 'stop'). The assistant content field holds the model's text response.
