# Relaystation Route Calculator

> Relaystation Route Calculator is a paid API for AI agents from api.relaystation.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Calculates a route between two geographic coordinates, returning distance, duration, and geometry as JSON

## Facts

- Endpoint: POST https://api.relaystation.ai/v1/location/route
- Price: $0.01/call
- Payment: x402
- Status: unknown

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 relaystation-route-calculator-db1f0d74 -d '<json body>'
```

Example prompt: Can you calculate a driving route from coordinates 37.7749, -122.4194 to 37.3382, -121.8863 and tell me the distance and estimated travel time?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01) route calculation between two coordinate pairs and want JSON back with distance, duration, and geometry. Ideal for agents handling logistics, delivery planning, map rendering, or travel time estimation where a lightweight routing call is sufficient and you want unified billing across Relaystation's tool suite.

## Known failure modes

- Invalid or out-of-range coordinates cause a 4xx error
- Unsupported travel mode enum value returns a validation error
- Origin and destination too close or identical may return degenerate route
- Network routing failure if coordinates are in an area with no road coverage
- Missing required fields (origin, destination) return a schema validation error
- Insufficient x402 balance results in payment failure before route calculation

## How this service works

$0.01/route. Calculate a route between two points — distance, duration, and geometry back as JSON. 155 tools, one balance — relaystation.ai

## Output

Returns a JSON object containing the calculated route between two coordinate pairs, including total distance, estimated travel duration, and route geometry (polyline or coordinates) suitable for map rendering or logistics planning.
