# Token Supply Snapshots — Daily Sum Series & Keyed Dataset Comparison

> Token Supply Snapshots — Daily Sum Series & Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-26).

Computes a daily sum time series and a keyed dataset comparison for up to 200 token supply snapshot records (circulating_units, total_units) using local analytical engines.

## 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-daily-sum-series-keyed-dataset-comparison-d6fb4bcd -d '<json body>'
```

Example prompt: I have two sets of token supply snapshots for groups 'btc' and 'eth' from 2024-01-01 to 2024-03-31 — can you compute the daily sum series for circulating_units and also compare the two datasets by key to spot differences?

## When to prefer this

Choose this endpoint when you have up to 200 pre-collected token supply snapshot records and need both a daily time series aggregation and a side-by-side dataset comparison in a single call. It is ideal for offline or batch analytical workflows where no live market data lookup is needed. Prefer it over live data APIs when you already have the raw snapshot data and simply need structured analytical outputs (sum series + diff report) at low cost ($0.01 per call for both reports).

## Known failure modes

- Input array exceeds 200 rows — request will be rejected or truncated
- Missing required row fields (row_id, date, circulating_units, total_units) causes validation failure
- Date strings not matching YYYY-MM-DD pattern will fail schema validation
- Numeric values outside ±1,000,000,000,000 range will be rejected
- Empty rows array (minItems:1 not met) will cause an error
- Mismatched row_ids between primary and 'other' datasets may produce incomplete comparison results

## How this service works

Token supply snapshots — Daily sum series + Keyed dataset comparison: Daily sum series + Keyed dataset comparison 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 analytical reports: (1) a daily sum time series aggregating the selected field (circulating_units or total_units) across all rows per date, and (2) a keyed dataset comparison report matching rows between the primary dataset and the 'other' dataset by row_id, highlighting differences in the selected field. Both reports are computed locally with no external data lookups.
