## 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 coco-json-fix-json-validation-and-repair-tool-47a5132f
```

Example prompt: I have a broken JSON string that won't parse — can you run it through the json-fix tool on CoCo to repair it and give me back valid, corrected JSON?

## When to prefer this

Choose this endpoint when you have a JSON string that fails to parse due to syntax errors (missing quotes, trailing commas, unescaped characters, etc.) and need it automatically repaired. Useful when working with LLM-generated JSON, user-provided JSON, or third-party API responses that are nearly-valid but syntactically broken. Prefer this over manual parsing logic when you need a quick, cheap automated repair step in a pipeline.

## Known failure modes

- Input JSON is so severely malformed that repair is impossible
- Non-JSON input provided (e.g. plain text, XML) that cannot be interpreted as JSON
- Empty input returns ambiguous or error response
- Network timeout for large JSON payloads

## How this service works

Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.

## Output

Returns a JSON object containing three fields: 'repaired' (the corrected JSON as a parsed object), 'repaired_text' (the corrected JSON as a formatted string), and 'was_valid_json' (a boolean indicating whether the original input was already valid JSON).
