How this service works
BitBooth JSON Repair: take any almost-JSON string (LLM tool output, broken API response, etc.), fix the common errors (trailing commas, single quotes, unquoted keys, missing brackets), and optionally validate against a JSON Schema. Built for AI agents that wrap every tool call in defensive parsing. Pay 0.001 USDC per call, no API key, no subscription.
Output
Returns the repaired, valid JSON string along with a flag indicating whether the input required changes, details of what was fixed, and optionally a JSON Schema validation result including any schema errors found.
Example use cases
Fixing LLM tool call output
“My AI pipeline's tool-call response came back with trailing commas and single-quoted strings and it's crashing my parser. Can you fix this JSON for me: {name: 'Alice', age: 30,}”
Schema validation after repair
“I have this broken JSON from a third-party API — it has missing brackets and unquoted keys. Fix it and then validate it against my JSON Schema to make sure it has the required fields: {"type":"object","required":["id","email"]}.”
Defensive parsing in agentic workflow
“Before I pass this tool output downstream, I want you to repair any JSON errors in it and confirm it's valid — here's the raw string: {"results": [1, 2, 3,], "status": 'ok'}”
Technical details
Endpoint
POSThttps://app.heinrichstech.com/v1/cdp/json-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent receives JSON output from LLMs or third-party APIs that frequently contains common syntax errors like trailing commas, single quotes, or unquoted keys. It is ideal for defensive parsing pipelines where structured output cannot be trusted to be valid, especially when you also need JSON Schema validation in the same call. At $0.001 per call with no API key, it is suitable for high-frequency agentic workflows. Prefer it over rolling your own regex-based fixer when you need reliable, schema-aware repair.
Side effects
- Input is so malformed it cannot be parsed even heuristically — returns error with description of unparseable content
- Provided JSON Schema is itself invalid — returns schema parse error
- Input is not JSON-like at all (e.g. plain text or binary) — returns cannot-repair error
- Payment of 0.001 USDC fails or is insufficient — returns payment error
- Rate limiting or server error — returns 5xx with error message
