Deterministic A2A Broken-JSON Repair & Schema Validator
Deterministic A2A Broken-JSON Repair & Schema Validator is a paid API for AI agents from alpha-stream.agentdiet.dev, paid per call via MPP, $0.002/call, status unknown (last checked 2026-10-21).
Repairs truncated, malformed, or markdown-wrapped JSON strings from LLM outputs so multi-agent pipelines can continue processing without crashes.

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://alpha-stream.agentdiet.dev/v1/repair)
Output
A repaired, standards-compliant JSON object reconstructed from the malformed input, with issues like trailing commas, markdown fences, single quotes, and truncation corrected so it can be parsed without errors.
Example use cases
Fixing LLM output in agent pipeline
“The model returned this JSON with a trailing comma and it's breaking my parser — please fix it so I can pass it downstream: {"status": "ok", "items": ["a", "b",]}”
Stripping markdown fences from JSON response
“I got a JSON response back from my AI wrapped in triple backtick markdown fences and my pipeline can't parse it — can you strip those out and return valid JSON?”
Repairing single-quoted JSON from model
“My agent output this JSON using single quotes instead of double quotes and it fails JSON.parse — please convert it to valid JSON: {'user': 'bob', 'score': 42}”
Technical details
Endpoint
GEThttps://alpha-stream.agentdiet.dev/v1/repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your multi-agent or LLM pipeline frequently receives malformed JSON — especially outputs with trailing commas, markdown code fences, single quotes, or truncation — and you need a deterministic, reliable fix rather than a probabilistic re-prompt. Ideal for production pipelines where crashes are costly and re-calling the LLM is slow or expensive.
Side effects
- Input JSON is too severely truncated or corrupted to deterministically repair — returns error indicating unrecoverable structure
- Input string is empty or missing — returns 400-style validation error
- JSON is structurally ambiguous after repair — may return best-effort result that differs from original intent
- Rate limiting or payment failure via x402 micropayment protocol
