  • repair_json

    Repair malformed JSON produced by an LLM or agent (trailing commas, missing quotes, code fences, chatty text around the JSON, <think> blocks, double-encoded JSON) and check the result against a JSON Schema. Returns the repaired value, what was changed, what could not be fixed (unresolved_errors), and `truncated: true` when the input looks cut off (e.g. by a token limit) so you can retry instead of trusting it. It never invents missing data. Free trial, no signup: 20 calls per client per day, 20000 characters per call.
