APIs

Morpho REST API (Vault and Market Data)

Reward APRs come from Merkl, not the Morpho API.

Documentation: Morpho API

Use Cases:

Fetch vault APY excluding rewards
Get market supply and borrow APYs excluding rewards
Read supported historical data using fixed lookback windows

Merkl API (Primary for User Rewards)

Merkl's REST API for current reward programs and user claimable amounts.

Base URL: https://api.merkl.xyz/
Documentation: api.merkl.xyz/docs
Key Endpoint:
- User Rewards (includes the cumulative amount, claimed, and merkle proofs needed to claim): GET /v4/users/{address}/rewards?chainId={chainId}

Use Cases:

Fetch user claimable rewards (current programs)
Get Merkle proofs for claiming
Real-time reward accrual (updates every 8 hours)

The rewards.morpho.org API has been deprecated. If you or your users have unclaimed rewards from historical Morpho programs (pre-Merkl migration), they can be claimed directly through the legacy rewards lookup app:

👉 rewards-legacy.morpho.org

All new reward programs are distributed exclusively via Merkl. See the Merkl documentation for integration details.

Smart Contracts

Merkl Distributor Contracts

All Merkl smart contract addresses, categorized by chain are listed here.

Key Functions:

claim(address[] users, address[] tokens, uint256[] amounts, bytes32[][] proofs) - Claim cumulative Merkl reward amounts

SDKs & Tools

Morpho SDKs

While there's no dedicated rewards SDK, you can use Morpho's core SDKs for related functionality:

@morpho-org/morpho-sdk: The default SDK for vaults and markets - entity classes (/entities) and Viem-based fetchers (/fetch) via subpath exports
@morpho-org/simulation-sdk: Simulate transactions
