## 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 workflows-agentdiet-dev-deterministic-a2a-broken-json-repair-schema-c8d29f96
```

Example prompt: This LLM response came back with broken JSON — it has trailing commas, single quotes, and markdown code fences — can you repair it so my pipeline can parse it: ```{name: 'Alice', age: 30,}```?

## When to prefer this

Choose this endpoint when your multi-agent pipeline or LLM workflow is receiving broken, truncated, or syntactically invalid JSON that needs to be deterministically repaired rather than re-generated — especially when you need reliability and repeatability over probabilistic LLM-based repair. Ideal for production pipelines where you cannot retry the upstream LLM call.

## Known failure modes

- Input JSON is so severely malformed that deterministic repair is not possible
- Empty or non-JSON input string
- JSON truncation too deep to reconstruct structure
- Rate limiting or payment failure via x402 protocol

## 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://workflows.agentdiet.dev/v1/malformed-json-healer)

## Output

Returns a repaired, well-formed JSON object that has been cleaned of common LLM output artifacts such as trailing commas, markdown fences, single-quoted keys/values, and truncation issues — ready for downstream parsing in multi-agent pipelines.
