How this service works
Per-pool APY/TVL time series (default 30d, APY percent unit) for trend and volatility analysis of one pool_uid. Use for 'is this pool's APY stable', '这个池子收益稳不稳'.
Output
A time series array of daily records for the specified pool, each containing a date, APY value (in percent units), and TVL figure, covering the requested lookback window (7–180 days, default 30). Useful for computing rolling averages, standard deviation of yield, and spotting sudden APY spikes or TVL outflows.
Example use cases
Stability check before depositing
“Before I put stablecoins into the Curve 3pool on Ethereum, can you grab its APY and TVL history for the past 60 days from Barker and tell me if the yield has been steady or all over the place?”
Volatility comparison for portfolio selection
“I'm deciding between two DeFi pools — can you get me 30 days of APY history for pool 'compound-v3-usdc-eth' from Barker so I can see how volatile its returns have been compared to the one I'm already in?”
TVL trend monitoring for risk assessment
“Has the TVL in pool 'morpho-usdc-mainnet' been growing or declining over the last 90 days? Pull the Barker history so I can assess whether liquidity is leaving that pool.”
Technical details
Endpoint
GEThttps://mcp.barker.money/barker_pool_historyWhen to prefer
Use this endpoint when you need time-series APY/TVL data for a single specific pool identified by its pool_uid — ideal for stability analysis, volatility scoring, or trend visualization before a deposit decision. Prefer this over the pool dossier endpoint when you need historical trend data rather than a current snapshot, and over the stablecoin benchmark endpoint when you want pool-specific rather than asset-class-level history.
Side effects
- Missing pool_uid parameter returns a validation error
- Unknown or unindexed pool_uid returns empty or 404-style error
- days value outside 7–180 range is rejected with a schema validation error
- Pool with insufficient historical data may return fewer rows than requested
- Payment not included or insufficient USDC results in 402 Payment Required
