API

Earn has a public HTTP API, so AI agents and apps can do what the app does without a browser.

• Read vaults and strategies, create and close strategies, get ready-to-sign transactions.
• Non-custodial: the API returns unsigned transaction data for your wallet to sign.
• No API keys or logins. Actions are authorized by wallet signatures (SIWE).

What you can do

The API lets you:

• Read vaults, strategies, and positions
• Create a new strategy
• Close an existing strategy
• Get transaction data for approvals, deposits, and withdrawals

How authorization works

Earn stays non-custodial. The API only ever returns unsigned transaction data for your wallet to sign and broadcast; it never holds your keys or moves funds.

• Reads are open, no auth required
• Writes (create, close) require a Sign-In-with-Ethereum (SIWE) signature
• The wallet that signs becomes the strategy owner
• No API keys or logins needed
