# Introduction

> Compress text and audio through a simple job-based API

Robin compresses content for LLM pipelines and storage. Send text or audio, pick a preset (or compose your own operation chain), get back a smaller output.

## What it does

* **Text**: whitespace/punctuation/unicode cleanup, and conversion of large JSON blocks to TOON tabular notation. Everything returns a job; small inline inputs come back already completed.
* **Audio**: silence trimming, loudness normalization, dynamic range compression, speedup, and re-encoding to Opus (default) or MP3. Always asynchronous.

## How it works

1. **Authenticate** every request with an API key: `Authorization: Bearer sk_live_...`
2. **Upload** files via a presigned URL (`POST /v1/upload`), or send text inline.
3. **Create a job** with `POST /v1/text` or `POST /v1/audio`, using a preset or custom operations.
4. **Get the result** from the response itself, via `GET /v1/jobs/:id?wait=25` (long-poll), or through a signed webhook.

All endpoints live under `/v1` and return a consistent envelope:

```json theme={null}
{ "success": true, "data": { ... } }
```

```json theme={null}
{ "success": false, "error": { "code": "JOB_NOT_FOUND", "message": "Job not found" } }
```
