## 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 github-audit-agentdiet-dev-deterministic-a2a-broken-json-repair-a1b42e7b -d '<json body>'
```

Example prompt: The LLM just returned this broken JSON with trailing commas and markdown fences — can you repair it so my pipeline doesn't crash? Here it is: ```{"name": "Alice", "age": 30,}```

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives LLM-generated JSON that fails standard parsing due to common LLM quirks like trailing commas, markdown wrapping, or single quotes. Ideal for automated pipelines where you need deterministic, crash-free JSON repair without human intervention. Prefer this over custom regex heuristics when you want a managed, paid API with idempotency guarantees.

## Known failure modes

- Input JSON is so severely malformed it cannot be deterministically repaired — returns error with details
- Empty or null raw_json input returns validation error
- Input that is not JSON at all (e.g. plain prose) may return unparseable error
- Extremely long or deeply nested JSON may hit size limits

## How this service works

Repairs truncated or malformed LLM JSON outputs (trailing commas, markdown fences, single quotes) so multi-agent pipelines never crash. (Live x402 v2, IETF MPP & MCP endpoint at https://github-audit.agentdiet.dev/v1/repair)

## Output

A repaired, valid JSON object that has been cleaned of common malformations such as trailing commas, markdown code fences, single quotes, and truncation artifacts, ready for downstream parsing and processing in multi-agent pipelines.
