# UOS Genesis compact_json

> UOS Genesis compact_json is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Compacts (minifies) a JSON payload by removing unnecessary whitespace and formatting

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 uos-genesis-compact-json-5efc7607 -d '<json body>'
```

Example prompt: Can you compact this JSON for me — strip all the whitespace and indentation so it's a single dense line: { "name": "Alice", "age": 30, "city": "New York" }?

## When to prefer this

Use this endpoint when you need a simple, reliable JSON minification utility with a predictable per-call cost and no setup. Prefer it over client-side minification when operating in agent pipelines where local code execution is unavailable, or when you need a consistent, auditable transformation step.

## Known failure modes

- Invalid or malformed JSON input returns an error response
- Empty input may return an error or empty result
- Very large JSON payloads may hit size limits
- Non-JSON content type or encoding issues may cause parsing failures

## How this service works

UOS Genesis machine utility: compact_json

## Output

Returns the input JSON as a compacted single-line string with all unnecessary whitespace, newlines, and indentation removed, preserving the original data structure and values exactly.
