## 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 json-fixer-repair-ab547bd5 -d '<json body>'
```

Example prompt: Can you fix this JSON for me — it has trailing commas and single quotes and won't parse: {'name': 'Alice', 'age': 30,}

## When to prefer this

Choose this endpoint when you have JSON that is syntactically invalid due to common human or LLM-introduced errors like trailing commas, single-quoted strings, or unquoted keys, and you need a fast, cheap ($0.005/call) programmatic fix without writing custom parsing logic. Avoid if the JSON is structurally corrupted beyond simple syntax issues.

## Known failure modes

- JSON is too structurally broken to repair (e.g. mismatched brackets) — may return an error or best-effort partial fix
- Input is not JSON at all — endpoint may fail or return unexpected output
- Ambiguous syntax may be repaired incorrectly, changing intended semantics
- Service unavailable if Cloudflare Tunnel goes offline (ephemeral URL)

## How this service works

Fix broken JSON (trailing commas, single quotes, unquoted keys). Returns only valid JSON.

## Output

Returns a valid, fully-parsed JSON object with all syntax errors corrected — trailing commas removed, single quotes replaced with double quotes, and unquoted keys properly quoted — ready to parse without further modification.
