# Token Annualised Simple Issuance Rate — IQR Outlier Flags

> Token Annualised Simple Issuance Rate — IQR Outlier Flags is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Calculates annualised simple issuance rates from token supply observations and flags statistical outliers using interquartile range (IQR) analysis.

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-iqr-outlier-flags-90deeb18 -d '<json body>'
```

Example prompt: I have 4 token issuance observations — period 30 days with 1000 tokens issued from a starting supply of 1,000,000; period 33 days with 1100 tokens from 1,100,000; another 30-day period with 1000 from 1,000,000; and one suspicious 33-day period with 9,500,000 tokens from 1,100,000. Can you run the IQR outlier flags check on these annualised issuance rates and tell me which observations are flagged as outliers?

## When to prefer this

Choose this endpoint when you have a set of raw token issuance observations (issued tokens, starting supply, period length) and need a fast, deterministic IQR-based outlier verdict on their annualised rates — without building your own statistical pipeline. Prefer it over generic statistics APIs when you need a pre-packaged crypto-native issuance rate calculation paired with outlier detection in a single call. Best suited for pre-audit checks, anomaly triage, or data cleaning on token supply series of up to 200 observations.

## Known failure modes

- Fewer than 2 observations submitted (minItems:2 requirement violated)
- More than 200 observations submitted (maxItems:200 exceeded)
- starting_tokens or period_days set to zero (exclusiveMinimum:0 violated)
- Missing required fields (issued_tokens, starting_tokens, or period_days) on any row
- Payment of 0.01 USDC not provided or rejected by x402 protocol
- Extremely skewed datasets may yield trivial IQR (all values identical), producing no meaningful outlier flags

## How this service works

Token annualised simple issuance rate — IQR outlier flags: IQR outlier flags 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 iqr outlier flags report.

## Output

Returns a bounded IQR outlier flags report for each submitted token observation, indicating which annualised simple issuance rate values are statistical outliers relative to the full set, based on interquartile range thresholds. Each observation receives a deterministic verdict (flagged or not flagged) computed from the supplied data — not a live scan or trade signal.
