## 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 vextorium-pool-yield-estimator-f09c250d -d '<json body>'
```

Example prompt: What's the estimated APR and 24h fees for the top liquidity pools for USDC on Ethereum — show me up to 5 pools with their liquidity, volume, and pool fee percentage?

## When to prefer this

Choose this endpoint when you need DeFi yield analytics for liquidity providers across any DEX Screener-supported chain, particularly when you want estimated APR, fees, and turnover data for a specific token or pool. Prefer this over generic DeFi aggregators when you need per-pool granularity including on-chain fee reads and daily rotation metrics. Use it for DeFi investment research, yield farming strategy, or liquidity provision due diligence.

## Known failure modes

- Token not found on the specified chain — returns empty pools array
- Pool address not valid or not recognized by DEX Screener — returns null or empty result
- Chain/network identifier not recognized — may return error or empty response
- No liquidity pool exists for the token — returns empty list
- On-chain fee read fails — pool fee may be null or estimated rather than exact
- Rate limit or payment failure — 402 or 429 response

## How this service works

Estimated yield of providing liquidity in a token's pools (or one pool) on any DEX Screener chain: liquidity, 24h volume, pool fee (read on-chain when possible), fees generated, estimated APR, turnover and age, sorted by APR.

## Output

Returns a list of liquidity pool objects for the queried token or specific pool, each containing: DEX name, token pair, pool address, link, pool age in days, tags/labels, liquidity in USD, 24h volume in USD, pool fee percentage, 24h fees generated in USD, estimated APR percentage, and daily turnover ratio. Also includes the network name, a source attribution, and an optional note.
