# Registry Snapshots Base-100 Series and Two-Measure Correlation

> Registry Snapshots Base-100 Series and Two-Measure Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes a Base-100 index series and a two-measure correlation report for supplied registry snapshot data (registered_entities, changed_entities) across 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 registry-snapshots-base-100-series-and-two-measure-correlation-5688ef3f -d '<json body>'
```

Example prompt: Can you run a base-100 index series and a two-measure correlation on my registry snapshot data? I have 4 rows for group-a and group-b from October 2026, using registered_entities as the base field and starting the index at row 0.

## When to prefer this

Choose this endpoint when you have tabular registry snapshot data with registered_entities and changed_entities columns and need both a base-100 normalized trend series and a correlation report in a single API call. Ideal for analysts who want to compare relative growth across company groups and measure co-movement between registration counts and entity changes without any external data sources or live lookups.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds limit, request rejected
- Missing required fields (row_id, date, company_group, registered_entities, changed_entities) on any row — validation error
- Invalid date format (not YYYY-MM-DD) — pattern validation failure
- base_index out of range (>=number of rows) — index error
- Null values in both measures may degrade correlation computation
- Payment of 0.01 USDC not provided or rejected — 402 response

## How this service works

Registry snapshots — Base-100 series + Two-measure correlation: Base-100 series + Two-measure correlation for supplied registry snapshots records (registered_entities, changed_entities). 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 computed from the supplied rows: (1) a base-100 normalized index series for the selected field (registered_entities or changed_entities) anchored at the specified base_index row, and (2) a two-measure correlation report quantifying the relationship between registered_entities and changed_entities. Both reports are computed entirely from the supplied data with no external lookups.
