How this service works

USDC yield on Arc: every Morpho lending vault with rate, size and how much you can withdraw right now, read on chain every 15 minutes. Yield on Arc before you deposit: every lending vault Circle Earn Kit lists on Arc (Morpho Vault V2: Galaxy, Keyrock, Steakhouse, Gauntlet, Bitwise and more) with its rate (Circle's figure), its size, and how much a depositor can actually withdraw at this block (idle USDC plus the free supply of the market its withdraw path draws from, read on chain), where each…

Output

A JSON object with a timestamp, chain ID, list of all Morpho USDC lending vaults on Arc (each with name, address, APY, vault size, and withdrawable USDC at current block), aggregate totals (number of vaults, total USDC deposited, total withdrawable USDC), and a highlighted best-rate vault you can actually exit from right now. Data is read on-chain and cached for up to 15 minutes.

Example use cases

Finding best liquid USDC yield on Arc

“Which Morpho vault on Arc is paying the highest USDC APY that I can actually withdraw from right now? Show me the top options with their rates and how much is withdrawable today.”

Pre-deposit yield research for DeFi investor

“Before I deposit USDC into a Circle Earn Kit vault on Arc, can you pull all the current lending vault rates — things like Galaxy, Keyrock, Steakhouse, Gauntlet and Bitwise — along with how much is already locked up in each?”

Monitoring Arc vault liquidity for rebalancing

“I need to check how much USDC is withdrawable across all the Morpho lending vaults on Arc right now — I'm trying to figure out if I can move a large position out without getting stuck.”

Endpoint

GEThttps://apexfaucet.xyz/api/x402/arc-yield?utm_source=zero.xyz

When to prefer

Use this endpoint when you need real-time USDC yield intelligence specifically on Arc's Morpho Vault V2 ecosystem (Circle Earn Kit vaults), especially when liquidity and actual withdrawability matter — not just headline APY. Prefer this over generic DeFi aggregators when you need Arc-native, on-chain-verified data including idle USDC and free market supply calculations.

Side effects

On-chain RPC unavailability may cause stale or missing data beyond the 15-minute cache window
A vault's withdrawableNow may be 0 if all underlying market supply is fully utilized
Response may return ok:false if the upstream Arc node is unreachable
Individual vault entries may be missing or incomplete if a specific Morpho vault is unresponsive
