## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability santyvv-data-historical-apy-and-tvl-for-yield-pool-f8ca6746
```

Example prompt: Show me the historical APY and TVL trends for the USDC-ETH pool — I want to see how the yield and locked value have changed over time.

## When to prefer this

Choose this endpoint when you need historical time-series data specifically for APY and TVL of a single yield pool, especially for DeFi research, yield strategy evaluation, or portfolio performance review. Prefer this over general market data endpoints when the focus is on pool-level yield and liquidity history rather than token prices or broader chain TVL rankings.

## Known failure modes

- Unknown or unsupported pool identifier returns empty or error response
- Pool with no historical data returns minimal or null dataset
- Invalid query parameters result in 400 error
- Rate limiting or payment failure returns 402 or 429 status
- Pool address on unsupported chain returns no data

## How this service works

Historical APY and TVL for one yield pool

## Output

Returns a time series dataset containing historical APY (annual percentage yield) values and TVL (total value locked) figures for the requested yield pool, allowing analysis of how pool yields and liquidity have changed over time.
