How it works

Pick your door. Every path leads to same data layer.
STEP 1

Embed

Drop in the Connect widget. Your users connect their exchanges and wallets via OAuth. You own the UX. We handle the auth and connections.
STEP 2

Sync

Connect pulls data from 200+ sources and returns it in one clean, consistent schema. Real-time via webhook, or on-demand.
STEP 3

Build

Query holdings, transactions, DeFi positions, accounting records — choose exactly the data scopes your product needs. Nothing more.

Docs that don't suck. SDKs that actually work. A sandbox with no time limit.

Think of what Plaid does for bank accounts. We do that for crypto. Every exchange, every wallet, every DeFi protocol one integration, one schema, always up to date.

Your first call is free.

No credit card. No sales call. Full sandbox from the moment you sign up. Most developers have their first working API call in under 10 minutes.

Frequently asked questions

link arrow
Q: How is this different from building my own integrations?

You'd need to write and maintain 200+ separate integrations — each with its own auth, rate limits, and schema drift. Connect is one integration that covers all of them, and we handle every breaking change.

link arrow
Q: What does the data schema look like?

Everything is normalised into a single consistent schema across all sources. Holdings, transactions, DeFi positions — same structure whether you're pulling from Binance or a raw wallet address. Full schema is in the docs.

link arrow
Q: How does user consent work?

Users authenticate via OAuth and choose exactly which accounts they connect. You request only the data scopes your product needs. Users can revoke access at any time from the widget UI.

link arrow
Q: Can I initiate transactions, not just read data?

Read-write ships August 2026 — cross-chain swaps, DeFi deposits, and payments through Li.Fi. Sign up now and we'll notify you the day it goes live.

link arrow
Q: Is there really a free tier?

Yes — full sandbox access, forever. Every endpoint, mock data, no time limit. You only need to talk to us about billing when you're ready to go live with real user data.
