## 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-b1e03cc5 -d '<json body>'
```

Example prompt: Can you calculate my expected staking rewards for a pool using live on-chain data — I want to know how much I'd earn based on current consensus state?

## When to prefer this

Choose this endpoint when you need deterministic, live on-chain staking reward calculations backed by real blockchain consensus state rather than static or estimated data. It is ideal for agents requiring pay-per-call access without API keys or account registration, settling in USDC on Base via x402.

## Known failure modes

- Invalid or missing serviceId returns an error
- Malformed request JSON body causes a 400-level response
- Insufficient USDC payment via x402 results in payment failure and no computation
- Live chain data temporarily unavailable may cause timeout or error
- Unsupported pool or staking parameters return empty or error results

## How this service works

Staking Rewards Calculator: node-operated on-chain service Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-staking-rewards","request":"<input>"}. No account, no API key.

## Output

Returns computed staking reward projections based on live on-chain consensus data, including expected yield, APY, and reward amounts for the specified staking parameters.
