How this service works
Retrieves vault APY breakdown.
Output
Returns a structured breakdown of the vault's APY, including total APY and its individual components such as base yield, protocol incentives, and token rewards. Each component typically includes its contribution rate and source, allowing users to assess the sustainability and composition of the vault's yield.
Example use cases
DeFi yield source analysis
“Break down the APY for the USDC vault on Arbitrum — I need to know how much of the yield is base rate versus token incentives so I can assess sustainability.”
Vault comparison for portfolio decision
“Show me the APY breakdown for vault 0x4d73adb72bc3dd368966edd0f0b2148401a178e2 on Ethereum mainnet — I'm deciding whether the rewards-based yield is worth the risk versus a lower but stable base APY.”
Monitor vault yield composition changes
“Fetch the current APY breakdown for the wETH vault on Optimism so I can compare it to last week and see if the incentive rewards portion has dropped.”
Technical details
Endpoint
HEADhttps://api.vaults.fyi/v2/detailed-vaults/:network/:vaultId/apy?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need granular APY composition data for a specific vault — not just the headline APY number. It is ideal for yield sustainability analysis, comparing base vs incentive yields, and making informed DeFi investment decisions. Prefer this over the general vault listing endpoint when you already know the network and vault ID and need deep yield detail rather than a summary view.
Side effects
- Invalid or unsupported network identifier returns a 404 or error response
- Unknown vault ID for the specified network returns not found
- Network or vault ID mismatch causes empty or error result
- Vault may be deprecated or paused, returning zero APY or error
- Rate limiting may occur for high-frequency polling
