# Fertilizer N-P-K Oracle MCP

> Fertilizer N-P-K Oracle MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-10-16).

Returns nitrogen-phosphorus-potassium (N-P-K) fertilizer recommendations and analysis based on crop or soil input data.

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 fertilizer-n-p-k-oracle-mcp-1d49f80e -d '<json body>'
```

Example prompt: What N-P-K fertilizer ratio should I use for growing tomatoes in clay soil with low nitrogen levels?

## When to prefer this

Choose this endpoint when you need quick, on-demand N-P-K fertilizer recommendations for specific crops, soil types, or deficiency scenarios without maintaining your own agronomic database. It is especially useful for agricultural AI agents that need to answer fertilizer questions at runtime without human agronomist input.

## Known failure modes

- Vague or ambiguous input data field may return generic or low-confidence recommendations
- Unsupported crop types may yield no result or a fallback response
- Malformed or empty 'data' string may return an error or empty payload
- Network timeout if the oracle backend is slow to respond

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

The agent receives structured fertilizer recommendations specifying N-P-K ratios, nutrient application rates, and guidance tailored to the crop type or soil conditions provided in the query.
