## 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 uos-genesis-repair-json-f4bf148a -d '<json body>'
```

Example prompt: This API response I got back has broken JSON — missing a closing bracket and some unquoted keys — can you send it to the JSON repair service and give me back something I can actually parse?

## When to prefer this

Choose this endpoint when you have a JSON string that fails to parse due to syntax errors, missing brackets, unquoted keys, trailing commas, or similar structural issues, and you need a quick programmatic repair without writing custom parsing logic. It is part of a suite of utility functions available on the same host, making it convenient when you are already using other UOS Genesis utilities.

## Known failure modes

- Input is so corrupted that no valid JSON can be inferred — may return an error or best-effort partial result
- Ambiguous repair cases where multiple valid corrections exist may produce unexpected output
- Non-JSON input (e.g. plain text or binary) may fail or return an empty result
- Payment failure (402) if the x402 payment header is missing or insufficient

## How this service works

Repair malformed, invalid, or broken JSON-like text and return valid parseable JSON when recoverable. Useful for fixing machine-generated JSON, API responses, missing quotes, formatting errors, trailing commas, and structured-data ingestion pipelines. Price: $0.003 USDC via x402 on Base.

## Output

A repaired, syntactically valid JSON string recovered from the malformed input, ready to be parsed by standard JSON parsers.
