Get started

Quickstart, authentication, and sandbox, everything you need to make your first authenticated call.

If this is your first BlendFi call, you're in the right place. Three pages get you from "received my key" to "made an authenticated request" in about five minutes.

Quickstart

Five-minute path: set your environment, authenticate, create your first user. Copy-paste curl.

Authentication

Bearer-token deep dive. Key formats, capabilities, environment matching. Read once; reference later.

Sandbox & keys

Sandbox vs production, how to request a key, what changes when you graduate to live.

Then what?

Once you've made your first call:

Build an onramp

PIX → USDT. The full integration.

Build an offramp

USDT → PIX. The other direction.

Concepts

KYC, idempotency, webhooks, fees, errors, audit, the primers.

Recipes

End-to-end (Build an X) tutorials with copy-paste code.
