# Introduction

> What is ParseTx?

ParseTx is a batch-first transaction enrichment API for fintech developers.

You send us a messy bank transaction string like `AMZN Mktp US*1A2B3C4D5 Amzn.com/bill WA`. We send you back clean, structured JSON:

```json theme={null}
{
  "merchant": "Amazon",
  "domain": "amazon.com",
  "category": "Shopping",
  "mcc_code": "5411",
  "is_subscription": false,
  "confidence": 0.99
}
```

## Why ParseTx?

1. **Deterministic Cache:** The same string always returns the same entity.
2. **Batch Native:** Submit up to 500 transactions at a time.
3. **Sandbox Key:** 5,000 free transactions/month — no credit card. **Production Key:** Pay-as-you-go at \$0.001/tx from the first request.
