How this service works
Daily APY and TVL history for one yield pool, up to ten years, with a summary of latest, minimum, maximum and mean APY and the TVL change over the window. Use it when an agent is judging whether a pool's current yield is typical or an outlier before allocating to it.
Output
Returns a JSON object containing the pool UUID, a count of data points, an array of daily records (each with date, APY, APY base, APY reward, and TVL in USD), summary statistics for APY and TVL (min, max, mean, first, latest, changePct), the data source ('defillama-yields'), a fetchedAt timestamp, and the total number of historical points available.
Example use cases
Yield trend analysis for DeFi position
“Show me the daily APY and TVL history for DefiLlama pool 54e9b138-3146-4c1f-8dce-1cb948f5ef96 over the past 90 days — I want to see the min, max, and average yield.”
Long-term pool performance review
“Get me 365 days of APY history for pool a1b2c3d4-0000-1111-2222-333344445555 on DefiLlama so I can evaluate how stable the yield has been over the past year.”
Monitoring recent APY drop

Technical details
Endpoint
POSThttps://agent402.tools/api/defi-yield-historyWhen to prefer
Choose this endpoint when you need structured daily time-series data for APY and TVL for a specific DeFi liquidity pool identified by its DefiLlama pool UUID. It is ideal for trend analysis, volatility assessment, and performance benchmarking over custom time windows up to 10 years. Prefer it over generic DeFi APIs when you already have the pool UUID (e.g., from the defi-yields endpoint on the same platform) and need rich summary statistics alongside raw data points.
Side effects
- Invalid or unknown pool UUID returns an error or empty result
- Limit exceeds 3650 days and may be capped or rejected
- Pool has insufficient history for the requested window, returning fewer points than expected
- DefiLlama upstream unavailability causes stale or missing data
- Malformed UUID format causes a 400-level error
