## 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 lilambd-rising-history-8fff05c8
```

Example prompt: Pull the rising history from lilambd since January 1 2024, filtering by the 'language' theme and the 'events' table.

## When to prefer this

Choose this endpoint when you need to retrieve historical records from the lilambd 'rising' dataset, especially when you need to filter by time range, table name, or theme, and when attribution/licensing metadata matters for downstream use.

## Known failure modes

- Missing required 'since' parameter returns a validation error
- Invalid or unrecognized 'table' or 'theme' values may return empty data arrays
- Payment not included or insufficient triggers a 402 payment required response
- Malformed date string in 'since' may cause a parse error or empty result
- Server unavailability returns a 5xx error

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

Returns a JSON object containing an array of historical data records ('data'), a count of matching records ('count'), and an attribution string indicating the source licence for the data.
