Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 json-to-toml-converter-0561021d -d '<json body>'
```

Example prompt: Take this JSON object — {"name": "my-app", "version": "1.0.0", "debug": true, "port": 8080} — and convert it to a TOML document for me.

## When to prefer this

Use this endpoint when you need a strict, error-safe JSON-to-TOML conversion that explicitly rejects null values and non-object roots rather than silently producing a broken TOML file. Prefer it for configuration file workflows (Cargo, Hugo, pyproject.toml) where correctness is critical and you want deterministic conversion without hidden surprises.

## Known failure modes

- Input JSON root is not an object (e.g. an array or primitive) — returns an error
- Any value in the JSON is null — TOML has no null type, returns an error
- Malformed or invalid JSON — returns a parse error
- Input exceeds 256 KB size limit — rejected
- Missing or incorrect Content-Type or body format

## How this service works

JSON to TOML. POST a JSON object; the response is a TOML document. The root must be an object, because TOML's root is a table, and a null anywhere in the document is refused — TOML has no spelling for one. Both are errors rather than a file that quietly parses to something you did not write.

## Output

A plain-text TOML document (application/toml) representing the input JSON object, with all keys and nested structures serialized as TOML tables and values. Null values anywhere in the input cause an error rather than being silently omitted, and non-object roots are rejected.
