ParseTx: Transaction Enrichment API for Fintech Developers

ParseTx is a batch-first transaction enrichment API that transforms messy bank statement descriptors — like AMZN Mktp US*1A2B3C4D5 Amzn.com/bill WA — into clean, structured JSON with canonical merchant names, domains, categories, MCC codes, and subscription flags. Sign up, link a credit card, and make your first enrichment call in under 60 seconds.

What ParseTx Returns

Send a raw transaction string and receive a fully enriched merchant object:

{
  "results": [
    {
      "input": "AMZN Mktp US*1A2B3C4D5 Amzn.com/bill WA",
      "status": "complete",
      "source": "cache",
      "merchant": "Amazon",
      "domain": "amazon.com",
      "category": "Shopping",

      "is_subscription": false,

    }
  ],
