# Tree Canopy Observations — Row Ordering & Daily Sum Series

> Tree Canopy Observations — Row Ordering & Daily Sum 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).

Computes numeric row ordering and a daily sum series for up to 200 tree canopy observation records (canopy_m2 or plot_m2), returning two local analytical reports per call.

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 tree-canopy-observations-row-ordering-daily-sum-series-1a5f3a39 -d '<json body>'
```

Example prompt: I have 50 tree canopy observation records with dates, canopy_m2 values, and plot_m2 values grouped by station — can you run row ordering and a daily sum series on the canopy_m2 field for me?

## When to prefer this

Choose this endpoint when you have up to 200 tree canopy or plot area observation records and need both a ranked row ordering and a date-based daily sum series from your own supplied data, without any need for external data lookup or live satellite imagery. Ideal for offline analytical pipelines, ecological reporting, and urban forestry audits where the data is already collected and needs summarization.

## Known failure modes

- More than 200 rows submitted — exceeds the maximum row limit
- Missing required fields (row_id, date, canopy_m2, plot_m2, station_group) cause validation errors
- Invalid date format (must be YYYY-MM-DD) causes schema rejection
- Null values in the selected field may affect sum series completeness
- Payment of 0.01 USDC not provided or declined — endpoint inaccessible

## How this service works

Tree canopy observations — Numeric row ordering + Daily sum series: Numeric row ordering + Daily sum series for supplied tree canopy observations records (canopy_m2, plot_m2). 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: (1) numeric row ordering of the submitted observation records, and (2) a daily sum series for the selected field (canopy_m2 or plot_m2), computed entirely from the supplied data using local analytical engines — no external lookups or live data involved.
