How this service works
Read any ERC-4626 tokenized vault (Morpho, Yearn v3, Euler, Fluid, sDAI...) on-chain: underlying asset, total assets, shares outstanding, price per share and approximate TVL in USD.
Output
Returns a JSON object with the vault contract address, network, vault name, vault symbol, underlying asset (symbol, address, decimals), total assets (in asset units), shares outstanding (stakes), price per share (in asset units per share), approximate TVL in USD, and an optional explanatory note about the price per share.
Example use cases
Yield monitoring for DeFi portfolio
“Check the current price per share and TVL for the Morpho vault at 0xBBBBBbbBBb9cC5e90e3b3Af64bdAF62C37EEFFCb on Base — I want to know how much yield it has generated since launch.”
Comparing vault metrics across protocols
“Fetch the vault data for the Yearn v3 USDC vault at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — give me the underlying asset, total assets locked, and the current price per share.”
TVL snapshot for DeFi dashboard
“Get the approximate USD TVL and shares outstanding for the Fluid vault at 0x9Fb7b4477576Fe5B32be4C1843aFB1e55F251B33 on Ethereum so I can update my DeFi dashboard.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/erc4626-vault?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to read live on-chain ERC-4626 vault metrics — price per share, TVL, total assets, or share supply — for any major vault protocol (Morpho, Yearn v3, Euler, Fluid, sDAI) across Ethereum, Base, Arbitrum, Optimism, or Polygon. Prefer this over generic blockchain RPC calls when you want pre-decoded, human-readable vault data with USD approximations without writing contract ABI parsing logic.
Side effects
- Invalid or non-ERC-4626 vault contract address returns an error or null fields
- Unsupported network returns a validation error
- Contract address exists but vault is not deployed on the specified network
- TVL approximation may be stale if oracle price data is delayed
- Rate limiting or payment failure returns a 402 or 429 error
