## 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 amanchain-staking-rewards-calculator-ca832c1e -d '<json body>'
```

Example prompt: What staking rewards would I earn if I stake 500 AMAN tokens in the main pool on AmanChain — can you calculate the expected yield and APY based on the current live chain state?

## When to prefer this

Use this endpoint when you need real-time, deterministically computed staking rewards data pulled directly from live AmanChain consensus state, especially when on-chain accuracy matters more than estimated approximations. Prefer this over generic DeFi yield estimators when working specifically with AmanChain/AMAN token staking pools.

## Known failure modes

- Invalid or missing serviceId returns an error response
- Malformed request JSON body causes a 400-level error
- Payment not settled or insufficient USDC balance results in x402 payment required error
- Node unavailable or consensus state unreachable returns a service error
- Unsupported pool or staking configuration returns no data

## How this service works

Staking rewards calculator — APR by lock tier (flex, 90-day, 365-day) with daily and yearly yield projection for any AMAN amount. Deterministic on-chain execution by the AmanChain node — live consensus state, real blocks, pools and balances. Pay per call via x402 (USDC on Base), no account, no API key. POST JSON {"serviceId":"aman-staking-rewards","request":"<input>"}.

## Output

Returns computed staking reward figures including estimated yield, APY, and projected earnings based on live on-chain pool data and current consensus state for the specified input parameters.
