Grouped under jsonaut by shoggi211: near-identical description.

Repair malformed JSON from LLM tool calls and agent-to-agent handoffs — fixes trailing commas, single quotes, truncation, markdown code fences, comments, and python literals, and can validate/coerce the result against a JSON Schema. Free deterministic tier; pay-per-call LLM fallback via x402 (USDC on Base). Tools: repair_json, validate_json.
