How this service works
Safety and trust layer for AI agents: PII redaction, scam/phishing text scan, EVM/Solana address validation, IBAN checks, JSON repair, deep on-chain wallet risk scoring, x402 counterparty endpoint reputation checks. Free discovery endpoints included. Pay with USDC via x402 — no API keys.
Output
Returns a JSON object with an 'ok' boolean indicating success and a 'json' field containing the repaired, fully valid parsed JSON object if repair was successful.
Example use cases
Fix broken LLM JSON output
“The language model returned this JSON but it has syntax errors and my code can't parse it — please repair it: {"name": "Alice", "age": 30, "tags": ["admin", "user"}}”
Recover truncated API response
“I got a truncated JSON response from an upstream API and it's missing the closing brackets. Can you repair this and give me back valid JSON? Here's what I have: {"order_id": 12345, "items": [{"sku": "ABC", "qty": 2}”
Clean up JSON with unquoted keys
“This JSON snippet has unquoted keys and trailing commas and won't parse — can you fix it for me? It looks like: {name: 'Bob', scores: [10, 20, 30,]}”
Technical details
Endpoint
POSThttps://agent-guard.annushka1190.workers.dev/v1/json/repairWhen to prefer
Choose this endpoint when you need lightweight, pay-per-use JSON repair without managing API keys, especially in agentic pipelines that occasionally receive malformed JSON from LLMs, third-party APIs, or user input. It is ideal when you want a compliance-focused toolset that also handles PII and blockchain address validation on the same platform.
Side effects
- Input is so severely malformed that repair is impossible — returns ok: false
- Non-JSON input (e.g. plain text or binary) cannot be repaired
- Network or payment failure if USDC payment via x402 is not processed correctly
- Empty or missing body field results in a validation error
