# Saylor Innovations Shipment ETA

> Saylor Innovations Shipment ETA is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Calculates estimated shipment arrival time from distance, average speed, and optional handling hours

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 saylor-innovations-shipment-eta-1cffcddf
```

Example prompt: How long will it take to ship a package that has to travel 750 km at an average speed of 85 km/h, with 4 hours of handling time at the warehouse?

## When to prefer this

Choose this endpoint when you need a fast, simple, deterministic ETA calculation based purely on physics (distance ÷ speed + handling time) without real-world traffic, weather, or carrier-specific data. It is ideal for logistics planning tools, supply chain dashboards, or agent workflows that need a quick baseline transit estimate using known route parameters.

## Known failure modes

- Missing required parameter distance_km or average_speed_kmh returns an error
- Zero or negative distance/speed values may cause calculation errors or invalid results
- Non-numeric string values for numeric parameters will likely return a validation error
- Very large distance values may produce unrealistic but technically valid results with no warning
- Payment failure via x402 protocol results in 402 response before calculation is attempted

## How this service works

Shipment ETA calculator from distance, average speed and handling hours

## Output

Returns a JSON object with the input parameters echoed back (distance_km, average_speed_kmh, handling_hours), plus computed transit_hours (distance/speed), total_hours (transit + handling), total_days, estimated_arrival_after_hours, the formula used, rounding rules applied, a scope note explaining what the calculation covers and excludes, and a service note.
