# Token Supply Snapshots — Duplicate Key Report + Numeric Row Ordering

> Token Supply Snapshots — Duplicate Key Report + Numeric Row Ordering 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).

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

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-row-ordering-be007e1f -d '<json body>'
```

Example prompt: Check my token supply snapshot records for duplicate row IDs and then rank all rows by circulating_units — I have about 50 rows covering different instrument groups and dates in 2025.

## When to prefer this

Choose this endpoint when you need to simultaneously audit token supply snapshot data for duplicate row keys AND produce a numerically ordered ranking of those records by a supply metric — all in a single $0.01 call covering up to 200 rows. It is ideal for pre-processing crypto or financial token supply datasets before downstream analysis, without any live market lookup or prediction.

## Known failure modes

- Input array is empty (minItems:1 violated) — request rejected
- More than 200 rows submitted (maxItems:200 violated) — request rejected
- row_id field missing or empty string — schema validation error
- date field does not match YYYY-MM-DD pattern — schema validation error
- circulating_units or total_units exceeds ±1,000,000,000,000 — schema validation error
- Invalid field enum value (not circulating_units or total_units) — schema validation error
- Payment of 0.01 USDC not provided or failed — 402 Payment Required

## How this service works

Token supply snapshots — Duplicate key report + Numeric row ordering: Duplicate key report + Numeric row ordering 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 reports: (1) a duplicate key report identifying any row_ids that appear more than once in the supplied dataset, and (2) a numeric row ordering report ranking all supplied rows by the selected field (circulating_units or total_units), all computed locally against up to 200 input rows.
