# Geometry Destination Point Calculator

> Geometry Destination Point Calculator is a paid API for AI agents from x402-agent.kariguetoazul.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Computes the destination latitude/longitude after traveling a given distance along a bearing from a starting coordinate on a sphere

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 geometry-destination-point-calculator-9eff42a5 -d '<json body>'
```

Example prompt: Starting at latitude 40.7128 and longitude -74.0060, calculate the destination point if I travel 5000 meters at a bearing of 90 degrees clockwise from north.

## When to prefer this

Use this endpoint when you need a fast, pay-per-call spherical geometry calculation to find a destination coordinate from an origin, bearing, and distance — especially in agentic or automated workflows where integrating a full geospatial library is impractical. Ideal for navigation, geofencing, logistics, and robotics use cases where precision spherical Earth modeling is required.

## Known failure modes

- Out-of-range latitude (outside -90 to 90) returns a validation error
- Out-of-range longitude (outside -180 to 180) returns a validation error
- Distance exceeding Earth's circumference (40075000 m) is rejected
- Bearing outside 0–360 degrees is rejected
- Missing required fields may return 400 or null results
- Payment failure (x402 protocol) blocks request execution

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing the destination 'lat' (decimal degrees latitude, -90 to 90) and 'lon' (decimal degrees longitude, -180 to 180) representing the point on the Earth's surface reached after traveling the specified distance along the given bearing from the origin coordinates.
