# RSSI Triangulation MCP

> RSSI Triangulation MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.18/call, status unknown (last checked 2026-09-15).

Performs RSSI-based radio signal triangulation to estimate device or asset location from signal strength readings

## Facts

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 rssi-triangulation-mcp-c1328b66 -d '<json body>'
```

Example prompt: I have RSSI readings from three WiFi access points — AP1 at -55 dBm, AP2 at -70 dBm, and AP3 at -63 dBm — can you triangulate the device's position from those signal strengths?

## When to prefer this

Choose this endpoint when you need to estimate device or asset location from WiFi or radio signal strength readings (RSSI), particularly for indoor positioning where GPS is unavailable. It is best suited for IoT asset tracking, smart building applications, and any scenario involving signal-strength-based localization rather than GPS coordinates or map-based routing.

## Known failure modes

- Insufficient RSSI data points provided (fewer than 3 access points may prevent triangulation)
- Malformed or out-of-range RSSI values causing computation errors
- Missing required data field in the input payload
- Ambiguous signal readings leading to low-confidence or no position fix
- Service unavailable or timeout after payment deducted

## 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

Returns a computed location estimate derived from RSSI signal triangulation, likely including estimated coordinates or positional data indicating the probable location of the device based on the provided signal strength inputs.
