## 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 token-annualised-simple-issuance-rate-rolling-mean-report-aa417d42 -d '<json body>'
```

Example prompt: Calculate the rolling mean of the annualised simple token issuance rate for these 4 observation periods — period 1: 1,000 tokens issued from 1,000,000 starting over 30 days; period 2: 1,100 tokens issued from 1,100,000 starting over 33 days; period 3: same as period 1; period 4: same as period 2 — using a rolling window of 2.

## When to prefer this

Choose this endpoint when you need a deterministic, smoothed rolling mean of token annualised simple issuance rates across a series of historical or projected emission periods. It is ideal for tokenomics analysis, governance reporting, or protocol auditing where you have multiple discrete observation windows (issued tokens, starting supply, period length) and want to reduce noise via rolling averaging. Prefer this over raw per-period calculators when trend smoothing is the goal, and over live market data endpoints when the calculation is purely supply-based and offline.

## Known failure modes

- Fewer than 2 rows provided — minimum array length not met
- Window size exceeds number of rows — rolling mean cannot be computed
- issued_tokens or starting_tokens set to 0 or negative — exclusiveMinimum violated
- period_days set to 0 — exclusiveMinimum constraint violated
- More than 200 rows submitted — maxItems exceeded
- Non-numeric values passed for numeric fields — schema validation error
- Payment of 0.01 USDC not attached — x402 payment required error

## How this service works

Token annualised simple issuance rate — Rolling mean report: Rolling mean report for Token annualised simple issuance rate. Supplied token observations only. Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded rolling mean report report.

## Output

Returns a rolling mean report containing the annualised simple issuance rate for each observation row, along with rolling mean values computed over the specified window — deterministic output, no live price data or trade signals included.
