# Glassnode MVRV Z-Score

> Glassnode MVRV Z-Score is a paid API for AI agents from x402.glassnode.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns the MVRV Z-Score for a crypto asset, measuring whether it is overvalued or undervalued relative to its realized value using statistical standardization.

## 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 glassnode-mvrv-z-score-f3bcec78
```

Example prompt: What's the current MVRV Z-Score for BTC? I want to see if it's in overvalued or undervalued territory based on Glassnode's on-chain data.

## When to prefer this

Use this endpoint when you need a standardized, statistically rigorous on-chain valuation signal for Bitcoin or Ethereum — specifically when assessing whether the current market price is historically stretched relative to realized value. Prefer over simple MVRV ratio when you need cycle-top/bottom detection with z-score normalization. Glassnode is the authoritative source for this metric.

## Known failure modes

- Missing required 'a' (asset symbol) parameter returns a 400 error
- Unsupported asset symbol returns an error or empty dataset
- Payment not fulfilled results in a 402 Payment Required response
- Invalid interval or format enum value returns a validation error
- Network identifier not applicable for the requested asset may return empty data

## How this service works

MVRV Z-Score — MVRV Z-Score evaluates whether is overvalued or undervalued relative to its fair value by standardising the spread between market value and realized value. Data by Glassnode.

## Output

Returns a time-series array of objects, each with a Unix timestamp ('t') and the MVRV Z-Score value ('v'), indicating how many standard deviations the market cap deviates from the realized cap for the requested asset.
