How this service works
Tree canopy observations — Category frequencies + Two-measure correlation: Category frequencies + Two-measure correlation 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 sharing the same input rows: (1) a frequency table showing how many records fall into each station_group category, and (2) a two-measure correlation result quantifying the statistical relationship between canopy_m2 and plot_m2 values across the supplied rows.
Example use cases
Urban forest canopy coverage audit
“I've got 150 tree survey rows from three monitoring stations, each with canopy_m2 and plot_m2 measurements — can you tell me how many observations come from each station group and whether canopy size correlates with plot size?”
Seasonal tree canopy pattern analysis
“Here are 80 tree canopy observation records across two station groups from October 2026 — run frequency counts on the station groups and give me the correlation between canopy_m2 and plot_m2 so I can see if larger plots tend to have more canopy cover.”
Ecology research dataset QA check
“Before we publish our tree plot dataset, can you check the distribution of station_group categories and compute the canopy_m2 vs plot_m2 correlation across all 200 rows so we can report those stats in our methods section?”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-ib26-weather-17-108?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have up to 200 pre-collected tree canopy observation records and need both a categorical breakdown of station groups and a correlation between two numeric measures (canopy_m2 and plot_m2) in a single low-cost call. Prefer it over general statistics APIs when your data specifically involves canopy and plot area measurements and you want two bundled analytical outputs for $0.01 USDC. Not suitable for live sensor data lookup, predictions, or datasets exceeding 200 rows.
Side effects
- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum limit
- Missing required fields (row_id, station_group, date, canopy_m2, plot_m2) — validation error
- Dates not matching YYYY-MM-DD pattern — schema validation failure
- All canopy_m2 or plot_m2 values null — correlation cannot be computed
- Payment not provided or incorrect amount — x402 payment required error
