# Sift Geo Convert

> Sift Geo Convert is a paid API for AI agents from sift.srv1996466.hstgr.cloud, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-23).

Converts a spatial/geographic file from one coordinate reference system (CRS) and/or format to another, supporting GeoJSON, CSV, WKT, and shapefiles.

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-geo-convert-65b4b03f
```

Example prompt: I have a shapefile at https://example.com/boundaries.zip that uses EPSG:4326 — can you convert it to GeoJSON in EPSG:27700 (British National Grid)?

## When to prefer this

Use this endpoint when you need to reproject spatial data between coordinate systems or convert between geospatial file formats programmatically, especially from a URL-accessible file. It supports a broad range of input formats (GeoJSON, shapefile, CSV, GPX, KML) and CRS definitions. Prefer this over local GIS tools or GDAL when you need a simple pay-per-call API without standing up infrastructure. It complements /v1/geo/inspect, which provides metadata without converting.

## Known failure modes

- Invalid or unreachable spatial file URL — endpoint cannot fetch the file
- Unsupported source format — file is not GeoJSON, CSV, WKT, shapefile, GPX, KML, or GPX
- Unrecognized CRS code — EPSG code or CRS string is invalid or unknown
- CRS auto-detection failure when source_crs is omitted and the file has no embedded projection info
- Invalid 'to' format value — must be one of geojson, csv, wkt, shapefile
- Payment failure — USDC micropayment on Base not completed, no charge and no response

## How this service works

Convert and reproject map files (GeoJSON, shapefile, CSV, GPX, KML). Spatial file in, spatial file out: reads GeoJSON, zipped shapefile, CSV, GPX or KML and writes GeoJSON, CSV, WKT or zipped shapefile in any EPSG/PROJ/WKT system. Always longitude/easting first, reports the transformation and its accuracy in metres, and refuses data outside the target's area of use (spotting swapped lat/lon).

## Output

Returns the reprojected and/or reformatted geographic data in the requested output format (geojson, csv, wkt, or shapefile). The file content is delivered directly, with geometries transformed to the target coordinate reference system.
