## 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-data-tools-json-repair-2c2be246
```

Example prompt: Can you repair this broken JSON for me? The text is: {"name":"Ada","tags":["x" — it's missing the closing brackets and I need it fixed.

## When to prefer this

Use this endpoint when you have a JSON string that fails to parse due to syntax errors, truncation, missing brackets, unquoted keys, or other common formatting issues and you need a fast, cheap ($0.001 USDC), no-account-required fix. Prefer this over manual regex fixes or LLM prompting for JSON repair when cost and reliability matter.

## Known failure modes

- JSON is too severely corrupted to be automatically repaired
- Input is not JSON at all (plain text, XML, YAML) and cannot be meaningfully repaired
- Very large JSON payloads may exceed query parameter length limits
- Missing required 'text' query parameter returns an error

## How this service works

566 pay-per-call tools for AI agents over HTTP or MCP, from $0.002 a call, most at $0.01. Every caller gets 25 free calls; then pay per call in USDC via x402 (Base, Polygon, Arbitrum, Solana) or by card with prepaid credits from /credits. No account needed; failed calls are never charged; per-tool reliability is public at /status. Crypto: token prices and wallet portfolios from Uniswap v3, chain reads on Base, Ethereum, Arbitrum, Optimism and Polygon, OFAC sanctions screening. Web: Read public static documentation, pages, PDFs and RSS feeds as clean text, plus link previews and sitemaps. Business: company profiles, domain and email checks. Also Bitcoin, FX, weather, holidays, geocoding, AI text, and JSON, date and validation utilities.

## Output

Returns a JSON object with a boolean 'valid' field indicating whether the input was valid or needed repair, and a 'repaired' field containing the corrected JSON string.
