# agentdiet-json-normalizer

> agentdiet-json-normalizer is a paid API for AI agents from agentdiet.dev, paid per call via x402 or MPP, $0.002/call, status unknown (last checked 2026-10-20).

Repairs truncated or malformed LLM JSON outputs (trailing commas, markdown fences, single quotes) so multi-agent pipelines never crash on bad JSON.

## How to call it through Zero

```sh
zero fetch --capability agentdiet-json-normalizer-f66f89a0
```

Example prompt: My LLM just returned this broken JSON with trailing commas and markdown fences — can you repair it so I can parse it: ```{"name": "Alice", "score": 42,}```?

## When to prefer this

Choose this endpoint when your multi-agent pipeline receives LLM-generated JSON that fails standard JSON.parse() due to common LLM quirks: trailing commas, markdown code fences, single quotes, or mild truncation. It is deterministic (same input always yields same output), making it safe to use as a reliable normalization step. Prefer this over writing your own regex fixes when you want a hosted, pay-per-call microservice that handles the full range of common LLM JSON malformations without maintaining code.

## Known failure modes

- Input so severely malformed that deterministic repair is impossible — returns an error indicating unrecoverable JSON
- Empty or null raw_json query parameter — returns validation error
- Non-JSON content passed as input (e.g., plain text prose) — may return best-effort parse or error
- Extremely long truncated JSON where structural intent cannot be inferred — may produce incorrect completion

## 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://agentdiet.dev/v1/json-normalizer)

## Output

Returns a repaired, schema-valid JSON object with all syntax errors corrected: trailing commas removed, markdown fences stripped, single quotes converted to double quotes, and truncated structures closed. The response is immediately parseable JSON ready for downstream consumption in a multi-agent pipeline.
