# Token Annualised Simple Issuance Rate — Base-100 Rebase Report

> Token Annualised Simple Issuance Rate — Base-100 Rebase Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Calculates a base-100 rebased index of a token's annualised simple issuance rate across multiple supplied observation periods.

## 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-base-100-rebase-report-3d0b1ccc -d '<json body>'
```

Example prompt: Calculate the annualised simple issuance rate for my token across 4 observation periods — [30 days with 1000 tokens issued from 1,000,000 starting, 33 days with 1100 issued from 1,100,000 starting, 30 days with 1000 issued from 1,000,000, 33 days with 1100 from 1,100,000] — and give me a base-100 rebase report using period 0 as the base index.

## When to prefer this

Use this endpoint when you have explicit historical token issuance observations (issued tokens, starting supply, period length) and need a deterministic, normalised base-100 index of annualised simple issuance rates for comparison or trend reporting. Prefer this over raw rate calculators when you need a rebased index anchored to a specific reference period rather than raw percentages. Not suitable for live on-chain scanning, safety analysis, or trade recommendations.

## Known failure modes

- Fewer than 2 rows supplied — minimum 2 observations required
- base_index out of range — must be within 0 to (number of rows - 1)
- issued_tokens or starting_tokens exceed maximum (1e16) or are non-positive where exclusiveMinimum applies
- period_days is zero or negative — exclusiveMinimum of 0 applies
- More than 200 rows supplied — maxItems limit exceeded
- Malformed numeric inputs cause validation failure

## How this service works

Token annualised simple issuance rate — Base-100 rebase report: Base-100 rebase 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 base-100 rebase report report.

## Output

A base-100 rebased index report showing the annualised simple issuance rate for each supplied observation period, normalised relative to the chosen base period. Each row receives an indexed value derived from deterministic calculation of (issued_tokens / starting_tokens) scaled to an annual rate and then rebased to 100 at the reference index.
