# FieldPulse Irrigation Scheduler

> FieldPulse Irrigation Scheduler is a paid API for AI agents from fieldpulse.theaslangroupllc.com, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-14).

Returns ET0-based water budgets, soil-moisture deficits, next rain-event timing, and precise irrigation schedules for any crop and location

## Facts

- Endpoint: GET https://fieldpulse.theaslangroupllc.com/api/irrigation
- Price: $0.08/call
- Payment: x402

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 fieldpulse-irrigation-scheduler-5b2c35a6
```

Example prompt: Can you pull an ET0-based irrigation schedule for my corn field near Fresno, CA — I need the soil-moisture deficit, how much water to apply, and whether any rain is expected in the next 7 days that might let me skip the next cycle?

## When to prefer this

Choose this endpoint when an agent needs agronomist-grade irrigation recommendations grounded in ET0 evapotranspiration science, soil-moisture deficit calculations, and near-term rain forecasting — especially when optimizing water application timing and volume for a specific crop and field location. Prefer over generic weather APIs when the output must be actionable irrigation scheduling rather than raw weather data.

## Known failure modes

- Invalid or unsupported crop type returns an error or empty schedule
- Location coordinates outside supported coverage area returns a geographic bounds error
- Missing required parameters (crop or location) returns a 400-level validation error
- Weather data unavailable for location results in degraded forecast confidence or partial response
- Payment not received or insufficient USDC results in 402 Payment Required

## How this service works

Irrigation recommendation for grower and agronomist agents. Returns a FAO-56 ET0 water budget, antecedent rainfall, next rain-event timing, and irrigation scheduling for any crop and location.

## Output

Returns an ET0-based water budget (evapotranspiration reference values), current soil-moisture deficit, timing and probability of the next rain event, and a precise irrigation schedule specifying when and how much to irrigate for the specified crop and location.
