  • repair_json

    Repairs malformed JSON text (trailing commas, single quotes, unquoted keys, missing braces, markdown-fenced LLM output, etc.) and optionally validates the result against a JSON Schema. This is a paid tool: requires a JSON_REPAIR_API_KEY environment variable obtained by visiting the /signup endpoint of the API once.
