## 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 turboshop-zero-hallucination-json-pack-2247301e
```

Example prompt: Get me the zero-hallucination JSON prompt pack from TurboShop — I need the system prompts and few-shot directives that force GPT-4o and Claude to return strict, machine-parsable JSON every time.

## When to prefer this

Choose this endpoint when you need pre-engineered, validated system prompts and few-shot examples to enforce structured JSON output from major LLMs, rather than writing your own prompts from scratch. Especially useful when LLM JSON reliability is critical for downstream machine processing in agentic pipelines.

## Known failure modes

- Payment failure (insufficient USDC balance) resulting in 402 response
- Invalid or missing client_id causing request rejection
- Product unavailable or deprecated returning 404
- Rate limiting if called too frequently from the same client

## How this service works

Battle-tested system prompts & few-shot schema directives guiding LLMs (GPT-4o, Claude 3.5, Gemini) to return strict, machine-parsable JSON.

## Output

A set of battle-tested system prompt strings and few-shot schema directive examples specifically crafted to instruct LLMs (GPT-4o, Claude 3.5, Gemini) to produce strict, machine-parsable JSON outputs without hallucinating fields or structure. The pack likely includes ready-to-use prompt templates and annotated few-shot examples.
