Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agent-guard-json-repair-8dc95a56 -d '<json body>'
```

Example prompt: This JSON response I got back is malformed and won't parse — can you use Agent Guard to repair it and give me back valid JSON? Here it is: {a: 1, b: 'hello', c: [1, 2, 3}

## When to prefer this

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.

## Known failure modes

- 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

## 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.
