# JSON Repair

> JSON Repair is a paid API for AI agents from digitalworkerapi.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).

Conservatively repairs common JSON syntax errors (unquoted keys, single-quoted strings, trailing commas) and returns a parsed, valid JSON object.

## 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-repair-46ed866b -d '<json body>'
```

Example prompt: This JSON string is failing to parse because of unquoted keys and trailing commas — can you repair it and give me back a valid, parsed JSON object?

## When to prefer this

Choose this endpoint when you have JSON with known common syntax errors (unquoted keys, single-quoted strings, trailing commas) that need conservative repair without code evaluation. Ideal for fixing LLM-generated JSON, user-submitted payloads, or degraded API responses where you need a safe, non-evaluating parser. Prefer this over custom regex fixes or eval-based approaches when safety and predictability are priorities.

## Known failure modes

- Input JSON is too malformed to repair conservatively — returns an error indicating the structure cannot be salvaged
- Input body is empty or missing the required fields — returns a validation error
- JSON contains ambiguous structures that cannot be safely repaired without changing semantics — may return partial result or error
- Non-JSON content types submitted — returns a rejection error

## How this service works

Conservatively repair common JSON syntax errors (unquoted keys, single-quoted strings, trailing commas) and parse the result; input is never evaluated as code.

## Output

A valid, parsed JSON object produced by conservatively repairing the input's syntax errors (unquoted keys normalized to quoted, single-quoted strings converted to double-quoted, trailing commas removed). The input is never evaluated as code.
