# Sift Web Tools – Geo File Inspector

> Sift Web Tools – Geo File Inspector is a paid API for AI agents from sift.srv1996466.hstgr.cloud, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-23).

Inspects a remote geospatial file URL and returns metadata including format, CRS, geometry types, and feature count

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 sift-web-tools-geo-file-inspector-352ac812
```

Example prompt: Inspect this GeoJSON file for me — https://example.com/data/regions.geojson — and tell me its coordinate reference system, geometry types, and how many features it has.

## When to prefer this

Use this endpoint when you need quick metadata about a remote geospatial file — its format, CRS, geometry types, and feature count — without fully downloading or converting it. Prefer it over conversion endpoints when you only need to understand what a spatial file contains. It supports the widest range of geospatial formats (GeoJSON, shapefile, CSV, GPX, KML, any CRS) via a simple pay-per-call GET request billed in USDC on Base.

## Known failure modes

- URL is not a valid or accessible geospatial file — returns error
- Unsupported file format not recognized by the inspector
- File requires authentication and cannot be fetched remotely
- Network timeout fetching a very large spatial file
- Malformed or corrupt spatial file that cannot be parsed

## How this service works

Inspect a map file: format, feature count, geometry types, extent, CRS. Reads a spatial file URL and returns its format, feature count, geometry types, extent, declared coordinate system and fields.

## Output

A JSON object containing the detected input format (e.g. geojson, shapefile, CSV, GPX, KML), the source CRS (e.g. EPSG:4326), a list of geometry types present (e.g. Point, Polygon), and the total feature count.
