# Token Supply Snapshots — Duplicate Key Report + Numeric Distribution

> Token Supply Snapshots — Duplicate Key Report + Numeric Distribution is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Analyzes up to 200 token supply snapshot records to produce a duplicate key report and a numeric distribution analysis for circulating_units or total_units.

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-supply-snapshots-duplicate-key-report-numeric-distribution-2728fb95 -d '<json body>'
```

Example prompt: Check my token supply snapshots for duplicate row IDs and show me the numeric distribution of circulating_units — I have about 150 rows with fields row_id, instrument_group, date, circulating_units, and total_units.

## When to prefer this

Choose this endpoint when you have token supply snapshot data (up to 200 rows) and need both a duplicate key audit and a numeric distribution summary in a single call. It is purpose-built for crypto/token supply datasets with circulating_units and total_units fields, and is cost-effective at $0.01 USDC for both reports together. Prefer it over general-purpose data tools when you want a fast, offline analytical result without any external lookups or live market data.

## Known failure modes

- Fewer than 1 row submitted — returns validation error
- More than 200 rows submitted — exceeds maxItems limit, rejected
- Invalid date format (not YYYY-MM-DD) — schema pattern violation
- row_id missing or empty — required field error
- numeric values outside ±1,000,000,000,000 — schema range violation
- Invalid field enum value (not circulating_units or total_units) — rejected
- Payment not provided or insufficient — x402 payment required error

## How this service works

Token supply snapshots — Duplicate key report + Numeric distribution: Duplicate key report + Numeric distribution for supplied token supply snapshots records (circulating_units, total_units). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two independent analytical reports: (1) a duplicate key report identifying which row_id values appear more than once across the submitted records, and (2) a numeric distribution summary (e.g. min, max, quartiles, frequency bands) for the selected field — either circulating_units or total_units — across up to 200 submitted rows.
