## 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 coinopselect-treasury-yield-policy-api-d4a6d049
```

Example prompt: What is the current yield policy for the CoinOpSelect treasury? I need the full policy configuration details from their on-chain data API.

## When to prefer this

Choose this endpoint when you specifically need treasury yield policy configuration data from the CoinOpSelect on-chain data platform on Base, and you are set up to pay $0.01 USDC per call via the x402 payment protocol. Prefer this over generic DeFi data aggregators when you need CoinOpSelect's specific policy structure.
