## 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 x-data-gateway-json-repair-utility-110b3fe9 -d '<json body>'
```

Example prompt: Can you repair this broken JSON string for me? It's missing some closing brackets and has a trailing comma: '{"name": "Alice", "age": 30,'

## When to prefer this

Choose this endpoint when you have a malformed, truncated, or syntactically broken JSON string that needs to be recovered or normalized before downstream processing — especially useful for fixing LLM-generated JSON, webhook payloads with transmission errors, or user-submitted JSON with common syntax mistakes like trailing commas or unquoted keys. It is a lightweight, pay-per-call utility requiring no API key.

## Known failure modes

- Input string is so corrupted that intent cannot be inferred — returns empty or best-effort partial object
- Non-JSON input (e.g. plain text, XML) may produce unexpected or empty output
- Very large malformed payloads may time out or return partial repairs
- Missing required `body` field returns an error or empty data response

## How this service works

Live X/Twitter read API plus Base market intel for AI agents: profiles, search, timelines, replies, followers; Base gas, spot prices, token meta/pairs, Base token verdict cards, trending, DefiLlama TVL, wallet intel, x402 probe and text utilities. REST + MCP. Pay per call in USDC via x402 on Base and Solana — no API keys. Free upstream data + local scoring.

## Output

A JSON object with a `data` field containing the repaired, valid JSON structure parsed from the input malformed string. The response indicates the corrected version of the original broken JSON payload.
