How this service works
Repairs truncated or malformed LLM JSON outputs (trailing commas, markdown fences, single quotes) so multi-agent pipelines never crash. (Live x402 v2, IETF MPP & MCP endpoint at https://domain-osint.agentdiet.dev/v1/structured-output)
Output
A repaired, valid JSON object parsed from the malformed input string. The endpoint deterministically corrects issues like trailing commas, markdown code fences, single quotes, and truncation, returning a clean structured object ready for downstream agent or pipeline consumption.
Example use cases
Fix crashed agent pipeline JSON
“My downstream agent just crashed because the LLM returned JSON with a trailing comma and unclosed bracket — can you repair this raw string so I can continue the pipeline: '{"status": "ok", "items": [1, 2, 3,}'?”
Strip markdown fences from structured output
“The model wrapped its JSON response in triple-backtick markdown fences and now my parser is failing — please clean and repair this string: '```json
{"result": "success", "score": 0.95}
```'”
Recover single-quoted JSON from LLM
“I got back a response using single quotes instead of double quotes and it's not valid JSON — can you fix this malformed string so it becomes parseable: "{'user': 'bob', 'active': true}"?”

Endpoint
GEThttps://domain-osint.agentdiet.dev/v1/structured-output?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent or LLM pipeline frequently receives malformed, truncated, or markdown-wrapped JSON that breaks downstream parsers. It is especially valuable when you need deterministic (not probabilistic) repair, want to avoid writing custom JSON-cleaning logic, or are operating in a pay-per-call x402 micropayment context. Prefer this over manual regex cleaning or LLM re-prompting when reliability and consistency are critical.
Side effects
- Input is so severely malformed that repair is impossible — returns error indicating unparseable input
- Non-JSON content passed as raw_json (e.g. plain text, binary) — may return parsing error or empty object
- Extremely long truncated JSON where context is insufficient to infer missing structure — partial repair or failure
- Missing required raw_json parameter — returns 400 or validation error
- Payment not fulfilled (x402) — returns 402 Payment Required before processing
