## 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-db39551f -d '<json body>'
```

Example prompt: Can you fix this broken JSON for me? It has trailing commas and single quotes instead of double quotes: {'name': 'Alice', 'age': 30,}

## When to prefer this

Choose this endpoint when you have a specific JSON syntax repair task — trailing commas, single quotes, or unquoted keys — and need a fast, cheap fix without spinning up a full JSON linting library. Ideal for lightweight agent pipelines that need to normalize JSON from external or user-generated sources before further processing.

## Known failure modes

- Input is so malformed it cannot be unambiguously repaired — returns an error or best-effort guess
- Input is not JSON at all (e.g. plain text, XML) — may return error
- Extremely large payloads may time out or be rejected
- Ambiguous structure (e.g. conflicting bracket types) may produce unexpected output

## How this service works

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

## Output

A valid, standards-compliant JSON string with all syntax errors corrected — trailing commas removed, single quotes converted to double quotes, and unquoted keys properly quoted. The response body contains only the repaired JSON.
