## 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-miner-net-position-change-30-day-73551eb9
```

Example prompt: Pull the 30-day miner net position change for Bitcoin from Glassnode, aggregated across all miners, in USD denomination — I want to see if miners are net accumulating or distributing.

## When to prefer this

Use this endpoint when you need on-chain miner behavior data specifically measuring 30-day net supply changes, segmented by named mining pools (e.g. F2Pool, AntPool, ViaBTC) or aggregated. Prefer this over exchange flow metrics when the focus is miner selling/accumulation pressure rather than exchange inflows.

## Known failure modes

- Missing required 'a' parameter (asset symbol) returns a 400 error
- Invalid miner enum value returns a 400 validation error
- Unsupported currency or interval combination returns a 400 error
- Insufficient x402 payment or payment verification failure returns a 402 error
- Data not available for the requested time range returns empty array or 404
