About

What is DeBank?

DeBank is a portfolio tracker for Ethereum and EVM chains that shows token balances and DeFi positions per protocol. DeBank Cloud sells its data as an OpenAPI paid in units, with up to 100 requests per second on the Pro plan.

How DeBank works

DeBank Cloud's OpenAPI exposes the same wallet data the app shows.

User endpoints return an address's balance per chain, token list, and positions per protocol, either simple balances or complex portfolio items, on one chain or across all supported chains. Wallet endpoints return gas prices at slow, normal and fast levels and a transaction pre-execution call that simulates one or more transactions, for example an approval followed by a swap, on chains such as Ethereum, BNB Chain, Polygon, Avalanche and Optimism.

The Official Account service lets verified Web3 projects broadcast messages to 0x addresses through DeBank Hi, run a follower page and chat with users while seeing their on-chain holdings. DeBank Connect lets apps request a user's base, chain and social data with authorization. Only organizations with a live project, app or protocol can get a verified official account.

How to start with DeBank

For the API, register at cloud.debank.com with an email verification code to receive an access key, then buy units in the dashboard.
Every request sends the key in an AccessKey header to pro-openapi.debank.com, and the /v1/account/units endpoint returns your remaining balance plus 30 days of daily usage.
The Pro plan allows up to 100 requests per second.
Projects applying for an Official Account should register with a group email on their own domain, which DeBank says helps verification.

DeBank fees and limits

The API is prepaid in units bought in the DeBank Cloud dashboard; the docs do not publish a unit price or per-endpoint cost, so check the dashboard before you commit. DeBank states it will announce pricing and terms changes at least 3 months in advance and posts breaking API changes on its Twitter account.

Risks to know before using DeBank

DeBank Cloud's terms of service, last updated October 25, 2022, say fees are based on the services purchased rather than actual usage, cannot be cancelled and are not refundable.
DeBank Cloud can end the agreement for convenience, or take some or all services offline, with two weeks' email notice and no liability.
Free trials run up to 14 days and can be suspended or ended at any time, for any reason or none.
The terms disclaim any warranty on the accuracy of the information provided and forbid reselling or sharing your account and data.
For Official Account broadcasts, the attention fee paid to non-followers, usually $1, is refunded only if the message goes unread for 7 days.
