StatusUnknown

Output

Returns a clean, valid JSON payload extracted or repaired from the input text, ready for downstream parsing and use without any surrounding prose, markdown, or syntax errors.

Example use cases

Example prompt

“The model returned something like 'Sure! Here is the JSON you asked for: ```json {"name": "Alice", "age": 30,} ``` Hope that helps!' — can you extract just the clean, valid JSON object from that string?”

When to prefer

Choose this endpoint when an LLM or agent pipeline produces output that wraps JSON in markdown, prose, or contains minor syntax errors like trailing commas or missing brackets, and you need a reliable, paid-per-call extraction step before passing data downstream. Particularly useful in agentic chains where structured data integrity is critical.

Side effects

No JSON-like structure found in input — returns error indicating nothing extractable
Input is so malformed that repair is ambiguous — may return partial result or error
Rate limit or payment failure via x402 — returns 402 or 429 status
Service cold-start latency on Render free tier — first request may time out

Input

{
  "text": "The user asked me to extract data. Here's the response: ```json\n{\"name\": \"Test User\", \"email\": \"test@example.com\", \"status\": \"active\"}\n``` Please parse this carefully."
}

Output

{
  "data": {
    "name": "Test User",
    "email": "test@example.com",
    "status": "active"
  }
}
