## 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 yog-x402-json-repair-extraction-09dc2f62 -d '<json body>'
```

Example prompt: Can you repair this broken JSON for me? It's missing some quotes and brackets: {name: Sutt, hp:12, inventory: [sword, shield}

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.02 USDC) automated repair of broken or malformed JSON, field extraction from messy text, or lightweight text classification — especially in agentic pipelines where LLM outputs frequently produce syntactically invalid JSON that needs fixing before downstream processing.

## Known failure modes

- Unparseable input — text is too ambiguous or completely unstructured to infer JSON schema
- Input text is empty or missing — returns error response
- Payment failure — x402 micropayment of $0.02 USDC not completed, request rejected
- Malformed input schema — raw_text field absent from request body
- Classification ambiguity — text could belong to multiple categories with no clear winner

## How this service works

Yog x402 is a paid LLM-as-a-service API with three text capabilities plus a free-tier liveness ping, all paid via x402 USDC on Base. classify_text ($0.01) classifies text into one of your supplied labels — sentiment tagging, routing support tickets, labeling data for ML pipelines. json_repair ($0.02) fixes malformed/messy text into valid JSON — cleaning up LLM output or scraped JSON that's slightly malformed before further processing. extract_fields ($0.03) pulls named fields from source text and will not fabricate values — structured extraction from unstructured text (name/date/amount from invoices or emails).

## Output

Returns a JSON object with an 'ok' boolean indicating success and a 'result' object containing the repaired or extracted JSON data, e.g. {"ok":true,"result":{"hp":12,"name":"Sutt"}}.

## Request schema (JSON Schema)
