> Agent Data Bench – JSON Repair is a paid API for AI agents from x402.deepsense.stream, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-21).

Repairs malformed LLM-produced JSON by stripping markdown fences, normalizing smart quotes, removing comments and trailing commas, then returning the parsed value and a list of applied repairs or a precise parse error.

## How to call it through Zero

```sh
zero fetch --capability agent-data-bench-json-repair-c2ad1496
```

Example prompt: This JSON from the LLM response is broken — it has markdown fences, smart quotes, and a trailing comma. Can you repair it and give me the parsed value plus a list of what was fixed? Here it is: ```json {"name": "Alice", "age": 30, } ```

## When to prefer this

always

## How this service works

Repair almost-JSON produced by LLMs: strips markdown code fences, normalises smart quotes, removes comments and trailing commas, then parses. Returns the parsed value plus the list of repairs applied, or a precise parse error. Pure computation, no upstream data.

## Output

done
