# FieldPulse Soil Intelligence API

> FieldPulse Soil Intelligence API is a paid API for AI agents from fieldpulse.theaslangroupllc.com, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-13).

Returns live soil moisture at multiple depths, soil temperature, evapotranspiration, and soil-health signals for any geographic location.

## Facts

- Endpoint: GET https://fieldpulse.theaslangroupllc.com/api/soil-intel
- Price: $0.08/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-13

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-soil-intelligence-api-5df706d7
```

Example prompt: Pull live soil conditions for my field at 41.8781° N, 87.6298° W — I need soil moisture at all available depths, soil temperature, and today's evapotranspiration reading so I can make an irrigation call.

## When to prefer this

Choose this endpoint when you need real-time, multi-depth soil moisture, soil temperature, and evapotranspiration data for a specific field location to support irrigation scheduling, agronomic decisions, or soil health monitoring. Prefer this over general weather APIs when soil-specific signals at multiple depths are required rather than surface-level atmospheric data.

## Known failure modes

- Invalid or missing coordinates return a 400 error
- Location outside supported coverage area returns no data or an error
- Payment failure (x402) returns a 402 Payment Required response
- Rate limiting or quota exhaustion returns a 429 error
- Temporary sensor or data feed outage may return stale or unavailable data

## How this service works

Soil intelligence for grower and agronomist agents. Returns observed surface and root-zone soil wetness (fraction of saturation), computed FAO-56 evapotranspiration, and soil-health signals for any location.

## Output

Returns real-time soil moisture readings at multiple soil depths, soil temperature, evapotranspiration (ET) values, and soil-health indicator signals for the requested geographic location, enabling data-driven irrigation and agronomic decisions.
