# Map Tile Quadkey Converter

> Map Tile Quadkey Converter is a paid API for AI agents from map-tiles.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Converts a slippy-map tile x/y/z to a Bing Maps quadkey, or a quadkey back to x/y/z, returning the parent quadkey and four child quadkeys.

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 map-tile-quadkey-converter-8097c602
```

Example prompt: Convert tile x=3, y=5, zoom=4 to a Bing Maps quadkey and also give me the parent quadkey and its four children.

## When to prefer this

Use this endpoint when you need to convert between slippy-map tile x/y/z coordinates and Bing Maps quadkey format, or when you need the quadkey hierarchy (parent and children) for tile-based caching, indexing, or Bing Maps API integration. Prefer this over manual computation when working in environments where you cannot implement the bit-interleaving math yourself.

## Known failure modes

- Missing required input: must provide either (x, y, zoom) or (quadkey), not neither
- Invalid quadkey characters: quadkey must contain only digits 0–3, length 1–24
- x/y out of range for given zoom level
- zoom level out of valid range 0–24
- Malformed query parameters return error response

## How this service works

Convert a tile x/y/z to a Bing Maps quadkey, or a quadkey back to x/y/z, with its parent and four children.

## Output

Returns the quadkey string (if x/y/z was supplied) or the tile x, y, zoom (if quadkey was supplied), along with the parent quadkey one zoom level up and four child quadkeys one zoom level down.
