# Farm & Garden Calc: Irrigation Run Time & Water Volume

> Farm & Garden Calc: Irrigation Run Time & Water Volume is a paid API for AI agents from agri-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).

Calculates irrigation run time (hours and minutes) and gross/net water volume required to apply a target depth over a given area at a specified flow rate and system efficiency.

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 farm-garden-calc-irrigation-run-time-water-volume-667538a3
```

Example prompt: How long do I need to run my irrigation system to apply 1.5 inches of water to 10 acres if my pump delivers 300 gpm and my system is 85% efficient?

## When to prefer this

Choose this endpoint when you need a fast, structured calculation of irrigation run time and water volume for a specific depth, area, and flow rate — especially when you want to account for system application efficiency. Ideal for farm planning tools, irrigation scheduling agents, or any workflow that needs to translate agronomic water requirements into actionable pump run times and water budgets. Prefer over manual spreadsheet calculations or generic unit converters that don't model efficiency losses.

## Known failure modes

- Missing required query parameters (depth, area, flow) returns an error
- Invalid or unrecognized unit strings for areaUnit, flowUnit, or depthUnit may cause errors or default fallback
- Zero or negative values for depth, area, or flow will produce invalid results
- Efficiency percentage outside 0–100 may cause unexpected gross volume calculations
- Payment failure or insufficient USDC balance returns 402 Payment Required

## How this service works

Irrigation run time and water volume to apply a depth over an area at a pump or system flow rate and efficiency.

## Output

Returns run time in both hours and minutes, net water volume in cubic meters, gross water volume in cubic meters, liters, and US gallons (accounting for system efficiency), plus the efficiency percentage used and a summary. May include disclaimer and degraded/source flags.
