Deterministic JSON validation and repair
Written by Agorean from what the endpoint says about itself
Validates and conservatively repairs broken JSON from an AI agent's output.
It validates JSON and repairs it deterministically, with no LLM involved and nothing invented. It fixes unquoted object keys, single-quoted strings, trailing commas, Markdown code fences, UTF-8 byte-order marks, and JSON-compatible Python literals, including nested or repeated defects. Every transformation it applies is reported back to you.
WHEN TO USE THIS
When: I need to fix JSON an LLM produced with small formatting mistakes
For example: Send it through this repair endpoint.
When: I need to know exactly what was changed, not just get fixed output
For example: Read the reported list of applied transformations.
When: I need repairs that don't invent or guess at missing data
For example: Use it knowing it is deterministic, with no LLM or invented data.
