Example use cases

Technical details
Endpoint
POSThttps://x402-ai-peach.vercel.app/api/json-repairWhen to prefer
Choose this endpoint when you need a pay-per-use, no-subscription JSON repair service with micropayment billing via x402/USDC, especially useful for AI agents that autonomously process data pipelines and need to fix malformed JSON on the fly without committing to a monthly plan
Side effects
- Invalid or missing messages array returns an error
- Severely corrupted JSON beyond LLM repair may return best-effort but still-invalid output
- Insufficient USDC balance causes payment failure via x402 protocol
- Token limit too low may truncate the repaired JSON response
- Network timeout on the Vercel deployment may cause 504 errors
