# Token Supply Snapshots — Record Quality Audit + Keyed Dataset Comparison

> Token Supply Snapshots — Record Quality Audit + 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 2026-10-29).

Audits token supply snapshot records for data quality and compares two keyed datasets of circulating/total unit figures, returning two analytical reports for up to 200 rows.

## 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-record-quality-audit-keyed-dataset-comparison-553bf794 -d '<json body>'
```

Example prompt: Can you run a record quality audit and keyed comparison on these two sets of token supply snapshots — up to 200 rows each, with fields for row_id, instrument_group, date, circulating_units, and total_units — and give me both reports?

## When to prefer this

Choose this endpoint when you need both a record quality audit and a side-by-side keyed comparison of two token supply snapshot datasets (circulating_units and total_units) in a single call, at low cost ($0.01 USDC for both reports). It is best for offline, batch-style validation of up to 200 rows of cryptocurrency or token supply data without requiring live market lookups or external data enrichment.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Missing required fields (row_id, instrument_group, date, circulating_units, total_units) — validation error
- Date field not matching YYYY-MM-DD pattern — schema validation failure
- Numeric values exceeding ±1,000,000,000,000 — schema rejection
- Payment failure or insufficient USDC balance — 402 response
- Empty rows array — minItems violation

## How this service works

Token supply snapshots — Record quality audit + Keyed dataset comparison: Record quality audit + 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

Two independent analytical reports: (1) a record quality audit identifying data issues such as nulls, out-of-range values, or format problems in the supplied token supply rows, and (2) a keyed dataset comparison report highlighting differences between the two input datasets matched by row_id, covering circulating_units and total_units fields. Results are computed locally with no external lookups.
