## 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 cve-intel-agentdiet-dev-deterministic-a2a-broken-json-repair-schema-dfc150d7
```

Example prompt: This JSON from my LLM is broken — it has trailing commas, single quotes, and a markdown code fence wrapper. Can you repair it into valid JSON so my pipeline doesn't crash? Here it is: ```json {'name': 'test', 'value': 42,}```

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives malformed, truncated, or markdown-wrapped JSON from an LLM and needs deterministic (not AI-based) repair before passing data to a downstream tool. Ideal for production agent orchestration where reliability matters and you cannot afford nondeterministic re-prompting. Prefer over regex-based manual fixes when the malformations are compound (e.g. both trailing commas AND markdown fences AND single quotes at once).

## Known failure modes

- JSON is too severely corrupted to deterministically repair — returns error indicating repair was not possible
- Input string is not JSON at all (e.g. plain prose) — may return parse failure
- Ambiguous truncation that could resolve to multiple valid structures — may return best-guess or error
- Very large malformed JSON strings may exceed query parameter length limits
- Missing required raw_json parameter returns 400 error

## 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://cve-intel.agentdiet.dev/v1/structured-output)

## Output

A repaired, valid JSON object that has been cleaned of common LLM output artifacts including trailing commas, markdown code fences (backticks), single quotes, and truncation issues — returned as a parseable JSON object ready for downstream agent consumption
