How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a 'data' field containing the repaired JSON, a 'status' field ('ok' on success), and an 'roi_proof' object showing the compression_ratio_pct achieved during repair.
Example use cases
Fixing LLM-generated malformed JSON
“The AI returned some JSON but it's broken — there are missing commas and unclosed brackets. Can you repair it and give me valid JSON I can actually parse?”
Recovering corrupted API response
“I got a truncated JSON response from an external API and my parser is failing. Can you take this raw string and fix it so it's valid JSON again?”
Cleaning scraped JSON data
“I scraped some JSON data from a webpage but it has formatting issues and invalid characters. Can you repair and normalize it into a clean JSON object?”

Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/json-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a paid, deterministic JSON repair service accessible via x402/USDC micropayment on Base, especially in agent pipelines where LLM outputs or API responses frequently produce malformed JSON that needs automated fixing without manual intervention.
Side effects
- Input JSON too malformed to repair — returns error status
- Missing required 'input' or 'method' fields in request body — returns schema validation error
- Empty or null raw_json query parameter — may return empty data object
- Network timeout if input is extremely large
- Payment failure via x402 — returns 402 if USDC payment on Base is not settled
