# Token Supply Snapshots — Record Quality Audit, String Normalisation & Exact Row Deduplication

> Token Supply Snapshots — Record Quality Audit, String Normalisation & Exact Row Deduplication 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).

Audits, normalises, and deduplicates up to 200 rows of token supply snapshot data (circulating_units, total_units), producing 3 independent analytical reports locally without any external lookups.

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-record-quality-audit-string-normalisation-57e5db03 -d '<json body>'
```

Example prompt: Can you run a quality audit, string normalisation, and exact deduplication check on my token supply snapshot records — I have about 50 rows with fields like row_id, instrument_group, date, circulating_units, and total_units, and I need all three reports back?

## When to prefer this

Choose this endpoint when you need three combined data-quality operations — record auditing, string normalisation, and exact deduplication — applied to token supply snapshot data (circulating_units and total_units) in a single $0.01 call covering up to 200 rows. It is ideal when you want offline, local analytical processing with no external data enrichment or predictions, and when cost efficiency for batch data cleaning is a priority.

## Known failure modes

- Rows array exceeds 200 items — request rejected
- Missing required fields (row_id, instrument_group, date, circulating_units, total_units) on any row — validation error
- Date field does not match YYYY-MM-DD pattern — schema validation failure
- Numeric values outside ±1,000,000,000,000 range — schema rejection
- Payment of 0.01 USDC not completed — 402 Payment Required response
- Empty rows array (minItems: 1 not met) — request rejected

## How this service works

Token supply snapshots — Record quality audit + String normalisation + Exact row deduplication: Record quality audit + String normalisation + Exact row deduplication for supplied token supply snapshots records (circulating_units, total_units). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Three independent analytical reports for the submitted token supply snapshot rows: (1) a record quality audit flagging missing, malformed, or out-of-range values in circulating_units and total_units; (2) a string normalisation report standardising instrument_group and other text fields; and (3) an exact row deduplication report identifying and removing identical rows. All analysis is performed locally with no external data lookups.
