How this service works
Exit capacity for USDC lending on Base: per-protocol utilization and withdrawable liquidity read from the protocol's own books (Aave, Compound), plus whether your size (?amountUsd=) can be withdrawn right now and what share of the market it would be. Protocols that do not expose borrowed-vs-supplied are marked unmeasured, never assumed liquid. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
Output
A per-protocol breakdown of USDC lending exit capacity on Base, including current utilization rates and withdrawable liquidity for Aave and Compound. If ?amountUsd= is provided, includes a boolean verdict on whether that size can be withdrawn immediately and what share of the total market it would represent. Protocols that don't expose borrowed-vs-supplied data are flagged as unmeasured rather than assumed liquid.
Example use cases
Pre-exit liquidity check for large position
“I'm about to pull out my $1.2 million USDC from Base lending — before I do anything, can you check whether there's actually enough exit liquidity across Aave and Compound to absorb that withdrawal right now?”
Portfolio risk monitoring for DeFi fund
“Check the current USDC exit capacity on Base for me — I want to see utilization rates on Aave and Compound and know what share of the market a $500,000 withdrawal would represent.”
Liquidity scouting before rebalancing
“I'm rebalancing my DeFi portfolio and considering moving USDC off Base. Can you pull the withdrawable liquidity figures from Aave and Compound on Base without any specific amount, just so I can see where the market stands?”
Technical details
Endpoint
GEThttps://yieldsignal.vercel.app/capacity/usdc-base-yield?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify actual withdrawable liquidity for USDC on Base before executing or planning a large exit from lending protocols. It is specifically suited for agents managing DeFi lending positions who need on-chain verified exit capacity rather than estimated or assumed liquidity. Prefer it over general APY or rate endpoints when the question is 'can I get out?' rather than 'what am I earning?'
Side effects
- Protocol data unavailable on-chain — endpoint may mark protocol as unmeasured rather than error
- Invalid or negative amountUsd parameter — likely returns 400 or validation error
- RPC/node failures reading Base chain data — may return stale or partial data
- Payment not processed (x402) — returns 402 with payment instructions before data is served
- Very large amountUsd values that exceed all available liquidity — verdict returns false with liquidity figures
