Sync-Convert

Request a demo key

We don't hand out self-serve free keys. Every demo request is reviewed, which means the ones we approve get real rate data rather than a crippled sandbox.

  1. 1

    You describe the use case

    Company, expected volume, and what you're converting. Two minutes.

  2. 2

    We review it by hand

    A real person reads it, usually within one business day. This is how we keep the demo tier free of abuse.

  3. 3

    You get credentials by email

    A live API key with 1,000 credits, hard-capped, valid for 30 days. No card, no sales call.

What the demo key includes

  • 1,000 call credits, hard-capped — never any overage charge
  • 60-second rate freshness on fiat and base crypto
  • 7 days of historical data
  • Expires 30 days after issue

One request per email domain every 30 days. We use your details only to review this request and issue credentials.
