# Token Annualised Simple Issuance Rate — Single Calculation

> Token Annualised Simple Issuance Rate — Single Calculation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Calculates the annualised simple issuance rate for a token given the number of issued tokens, starting supply, and observation period in days.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-single-calculation-50dd8c07 -d '<json body>'
```

Example prompt: Calculate the annualised simple issuance rate for a token that started with 1,000,000 tokens, issued 5,000 new tokens over a 30-day period.

## When to prefer this

Use this endpoint when you need a fast, deterministic, single-point calculation of a token's annualised simple issuance rate from known supply observations. It is ideal for one-off computations where you have discrete values for starting supply, newly issued tokens, and the observation period. Prefer this over batch or distribution-style endpoints when you only need a single result rather than histograms, comparisons, or multi-scenario reports.

## Known failure modes

- Missing required fields (issued_tokens, starting_tokens, or period_days) returns a validation error
- period_days must be greater than 0 (exclusiveMinimum); a zero value will be rejected
- starting_tokens must be greater than 0 (exclusiveMinimum); zero starting supply will be rejected
- Values exceeding the maximum bound (1e16) will be rejected
- Payment failure or insufficient USDC balance may result in a 402 response

## How this service works

Token annualised simple issuance rate — Single calculation: Single calculation 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 single calculation report.

## Output

A single calculation report containing the annualised simple issuance rate derived deterministically from the supplied token observations (issued_tokens, starting_tokens, period_days). The result reflects a bounded, deterministic computation — not a live market scan or trade recommendation.
