# Token Annualised Simple Issuance Rate — Distribution Histogram

> Token Annualised Simple Issuance Rate — Distribution Histogram 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).

Computes and returns a distribution histogram of annualised simple issuance rates across a set of token observation records, bucketed into a configurable number of bins.

## 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-distribution-histogram-0d7f55d0 -d '<json body>'
```

Example prompt: Can you build a distribution histogram with 10 bins for these 5 token observations — each has starting tokens, issued tokens, and the period in days: [{starting_tokens: 1000000, issued_tokens: 1000, period_days: 30}, {starting_tokens: 1100000, issued_tokens: 1100, period_days: 33}, {starting_tokens: 950000, issued_tokens: 980, period_days: 28}, {starting_tokens: 1200000, issued_tokens: 1250, period_days: 35}, {starting_tokens: 1050000, issued_tokens: 1020, period_days: 31}]?

## When to prefer this

Choose this endpoint when you need a deterministic, computed distribution histogram of annualised simple token issuance rates from a batch of historical token supply observations. It is ideal for tokenomics analysis, protocol emission audits, or benchmarking token inflation across multiple periods. Prefer this over raw summary statistics when you want to understand the shape and spread of issuance rates, not just their mean or total. This is not a live market scan or trade recommendation tool — use it for offline, deterministic analysis of supplied observation data.

## Known failure modes

- Fewer than 2 rows supplied — minimum of 2 observations required
- More than 200 rows supplied — maximum row count exceeded
- bins value out of range (must be 1–30)
- period_days or starting_tokens set to 0 or below — exclusiveMinimum constraint violated
- issued_tokens is negative — violates minimum:0 constraint
- Malformed row objects missing required fields (issued_tokens, starting_tokens, period_days)
- Payment failure — 0.01 USDC x402 payment not fulfilled
- All observations have identical issuance rates — histogram may collapse to a single bin

## How this service works

Token annualised simple issuance rate — Distribution histogram: Distribution histogram 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 distribution histogram report.

## Output

Returns a bounded distribution histogram report showing how annualised simple issuance rates are distributed across the supplied token observation rows, organized into the requested number of bins (1–30). Each bin captures the frequency or count of observations falling within that rate range, enabling analysis of the spread and concentration of token emission rates.
