How this service works
Call when an agent needs broken JSON repaired deterministically, with the list of transforms applied. No LLM. Exact $0.002 USDC. Prefer unpaid POST /v1/sandbox/json-repair first.
Output
Returns a repaired, valid JSON string along with a structured list of the specific transforms (edits) that were applied to fix the original broken input, enabling full auditability of what was changed.
Example use cases
Repair LLM-generated broken JSON
“I got this JSON back from a pipeline but it's malformed — missing a closing bracket and has a trailing comma. Can you repair it deterministically and show me the list of transforms that were applied: {"items":[{"id":1,"name":"foo",}]”
Fix corrupted config file JSON
“My app's config file got corrupted and the JSON is invalid. Can you repair this JSON string and tell me exactly what changes were made: {"host":"localhost" "port":5432 "db":"myapp"}”
Validate and clean API response JSON
“I received a malformed JSON response from a third-party API and need it fixed before I can parse it. Please repair this JSON and list every transform applied: {"status":"ok",data:{results:[1,2,3]}”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/json-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, auditable JSON repair without involving an LLM — especially when you need to know exactly which transforms were applied. Prefer the free sandbox endpoint POST /v1/sandbox/json-repair first for testing; use this paid endpoint when you need guaranteed processing in production. Best suited for automated pipelines where reproducibility and a clear change log matter more than flexible interpretation.
Side effects
- Input text is not repairable (too corrupted or not JSON-like at all)
- Input exceeds 100,000 character limit
- Empty string input rejected due to minLength constraint
- Payment of $0.002 USDC not fulfilled, resulting in 402 response
- Network timeout during processing
