# Token Supply Snapshots — String Normalisation + Base-100 Series

> Token Supply Snapshots — String Normalisation + Base-100 Series 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).

Applies string normalisation and base-100 index series transformations to user-supplied token supply snapshot records (circulating_units, total_units), returning two analytical reports for up to 200 rows.

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-string-normalisation-base-100-series-dc4714c5 -d '<json body>'
```

Example prompt: Take these token supply snapshots for BTC and ETH across October 2026 — up to 80 rows with circulating_units and total_units — and run string normalisation plus a base-100 index series starting from row 0 on the circulating_units field, giving me both analytical reports.

## When to prefer this

Choose this endpoint when you have already gathered token supply snapshot data locally and need fast, cheap ($0.01 USDC) string normalisation and base-100 series indexing applied to circulating_units or total_units, without requiring live market lookups or external data enrichment. It is well-suited for batch pre-processing of up to 200 rows before downstream charting or reporting.

## Known failure modes

- More than 200 rows submitted — request rejected, maxItems limit exceeded
- Invalid date format (not YYYY-MM-DD) — schema validation error
- base_index out of range (≥ number of rows submitted) — index error
- Numeric values outside ±1,000,000,000,000 — validation failure
- Missing required fields (row_id, date, circulating_units, total_units) — schema error
- Empty rows array — minItems:1 violation

## How this service works

Token supply snapshots — String normalisation + Base-100 series: String normalisation + Base-100 series 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 analytical reports: (1) string-normalised version of the supplied token supply rows, and (2) a base-100 index series computed over the selected field (circulating_units or total_units), anchored at the specified base_index row. Covers up to 200 input rows across any instrument groups.
