# Registry Snapshots — Numeric Interval Filter + Two-Measure Correlation

> Registry Snapshots — Numeric Interval Filter + 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 2026-10-23).

Filters registry snapshot rows by a numeric interval on a chosen field and computes a Pearson/rank correlation between registered_entities and changed_entities, returning two analytical reports for up to 200 supplied 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 registry-snapshots-numeric-interval-filter-two-measure-correlation-3b3f328c -d '<json body>'
```

Example prompt: I have registry snapshot data for two company groups across October 2026 — can you filter the rows where registered_entities is between 5 and 50, then run a two-measure correlation between registered_entities and changed_entities and give me two analytical reports?

## When to prefer this

Choose this endpoint when you have up to 200 registry snapshot rows with registered_entities and changed_entities fields and need both a numeric interval filter and a two-measure correlation in a single $0.01 call. Prefer it over general-purpose analytics tools when you want fast, local, no-external-lookup computation on structured registry data with a predictable schema. Use it instead of building custom SQL or Python scripts when the dataset fits within 200 rows and the two-report output format (interval filter + correlation) matches your analysis goals.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maxItems limit
- minimum greater than maximum — invalid interval produces empty filter result
- Non-numeric or null values in both measure fields — correlation cannot be computed
- Date strings not matching YYYY-MM-DD pattern — schema validation error
- Payment of 0.01 USDC not completed — 402 response, no reports returned

## How this service works

Registry snapshots — Numeric interval filter + Two-measure correlation: Numeric interval filter + 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 independent analytical reports: (1) the subset of input rows whose selected field value falls within the specified [minimum, maximum] numeric interval, and (2) a correlation analysis (e.g. Pearson or rank correlation) between registered_entities and changed_entities across those filtered rows. All computation is performed locally on the supplied data with no external lookups.
