# Garden Calculators – Drip Irrigation Calculator

> Garden Calculators – Drip Irrigation Calculator is a paid API for AI agents from garden-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).

Calculates weekly water volume, system flow rate, and run time per watering session for a drip irrigation system given area, target inches per week, emitter count, and emitter flow rate.

## 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 garden-calculators-drip-irrigation-calculator-1c5dedba
```

Example prompt: I have a 400 square foot vegetable garden with 20 drip emitters rated at 1 GPH each. I want to apply 1 inch of water per week in 3 waterings. My faucet puts out 2 GPM. How long should each watering run and is my supply sufficient?

## When to prefer this

Use this endpoint when you need precise drip irrigation math — specifically gallons needed per week, system flow rate, and per-session run times — for a defined garden area with known emitter specs. It is ideal over generic irrigation guides when you have concrete parameters (square footage, emitter count, GPH rating) and want a computed answer rather than a rule-of-thumb. Prefer it when you also want to validate whether a measured water supply (in GPM) can meet the system's demand.

## Known failure modes

- Missing required parameters (areaSqFt, inchesPerWeek, emitterCount, emitterGph) returns a 400 error
- areaSqFt outside range 1–1,000,000 causes validation failure
- emitterGph outside range 0.1–60 causes validation failure
- emitterCount outside range 1–5000 causes validation failure
- inchesPerWeek outside range 0.1–6 causes validation failure
- efficiencyPercent outside range 50–100 causes validation failure
- wateringsPerWeek outside range 1–14 causes validation failure
- Payment not included or insufficient USDC results in 402 response

## How this service works

Drip irrigation math: gallons for inches of water over an area, emitter flow, supply limit and run time per watering.

## Output

Returns computed values including total weekly gallons and litres, system flow in GPH and GPM, total hours of irrigation per week, hours per individual watering session, number of waterings per week, and optionally a supply limit check comparing system demand against the user's measured faucet or zone flow rate. May also include a summary, verdict, and disclaimer fields.
