# TBS Weather & Climate API – Soil & Agriculture Intelligence

> TBS Weather & Climate API – Soil & Agriculture Intelligence is a paid API for AI agents from x402.tbs-digital.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10).

Returns live soil moisture at four depths, soil temperature at multiple depths, reference evapotranspiration (ET0), vapour pressure deficit, and frost risk for any lat/lon or city.

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 tbs-weather-climate-api-soil-agriculture-intelligence-fd09ecc9
```

Example prompt: Pull the current soil moisture at all depths, soil temperature, ET0, vapour pressure deficit, and frost risk for my field at latitude 38.5 and longitude -122.8 — I need to decide whether to irrigate today.

## When to prefer this

Choose this endpoint when you need granular soil-layer data (moisture and temperature at multiple depths), ET0, vapour pressure deficit, and frost risk specifically for agricultural or irrigation decision-making. Prefer it over general weather endpoints when the use case is grower-facing, agronomist tooling, or crop management rather than atmospheric conditions alone. Ideal for precision agriculture agents that need soil-health intelligence at a specific GPS coordinate or named location.

## Known failure modes

- Missing both lat/lon and city — returns error requiring at least one location parameter
- Invalid latitude (outside -90..90) or longitude (outside -180..180) — returns validation error
- City name not recognized or ambiguous — may return no-match or wrong-location result
- No soil data available for remote ocean or polar coordinates — may return null agriculture fields
- Rate limiting or payment failure via x402 protocol — returns 402 Payment Required

## How this service works

Soil and agriculture intelligence for grower, agronomist and farming agents at any lat/lon. Returns live soil moisture at four depths, soil temperature at 0/6/18/54 cm, reference evapotranspiration (ET0), vapour pressure deficit and frost risk. For irrigation scheduling, soil-health monitoring and crop management.

## Output

A JSON object containing the queried location details, timestamp, and an agriculture block with: soil moisture readings at four depths, soil temperature at 0/6/18/54 cm, reference evapotranspiration (ET0), vapour pressure deficit, and frost risk indicator. Also includes payer address/network and a unique request ID.
