# Geospatial Tile Processing — Equal-Width Histogram + Secondary-Measure Weighted Mean

> Geospatial Tile Processing — Equal-Width Histogram + Secondary-Measure Weighted Mean 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 an equal-width histogram and a secondary-measure weighted mean for geospatial tile processing records (tile_count, processing_seconds) over up to 200 supplied 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 geospatial-tile-processing-equal-width-histogram-secondary-measure-695ab55a -d '<json body>'
```

Example prompt: Analyze my geospatial tile processing records — I have 50 rows with tile_count and processing_seconds — and compute an equal-width histogram with 10 bins on tile_count, plus the processing_seconds weighted mean.

## When to prefer this

Choose this endpoint when you have up to 200 geospatial tile processing records and need both a histogram distribution view and a weighted mean in a single low-cost call ($0.01 USDC). Ideal for offline or batch analytical summaries of tile processing pipelines where no live lookup or prediction is needed.

## Known failure modes

- More than 200 rows submitted — API rejects with validation error
- Invalid date format in row (must be YYYY-MM-DD)
- Missing required fields (row_id, tile_count, processing_seconds) in a row
- bins value outside 1–30 range causes validation failure
- Null values in measure fields may affect statistical output quality
- Payment failure or insufficient USDC balance prevents call

## How this service works

Geospatial tile processing — Equal-width histogram + Secondary-measure weighted mean: Equal-width histogram + Secondary-measure weighted mean for supplied geospatial tile processing records (tile_count, processing_seconds). 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) an equal-width histogram of the selected field (tile_count or processing_seconds) broken into the specified number of bins, with counts per bin; and (2) a weighted mean of the secondary measure. Both are computed locally from the supplied rows without any external lookups.
