## 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-entities-with-balance-1k-count-f6a00592
```

Example prompt: Can you pull the Glassnode on-chain data showing how many unique Bitcoin entities currently hold at least 1,000 BTC coins — I want the daily JSON time series for BTC.

## When to prefer this

Use this endpoint when you need authoritative on-chain data specifically about the count of entities holding ≥1,000 BTC, sourced from Glassnode's proprietary entity clustering methodology. Prefer this over address-based metrics when entity-level (cluster-adjusted) holder analysis is required, and over generic market data APIs when you need granular historical daily time-series of large-holder counts.

## Known failure modes

- Missing required 'a' (asset) query parameter returns 400 or validation error
- Unsupported asset symbol (non-BTC) rejected due to enum constraint
- Payment not provided or insufficient USDC triggers 402 Payment Required
- Invalid format ('f') or interval ('i') parameter returns error
- Service unavailability returns 5xx error
- Rate limiting or quota exhaustion returns 429

## How this service works

Number of Entities With Balance ≥ 1k — The number of unique entities holding at least 1,000 coins. Data by Glassnode.

## Output

A JSON array of timestamped data points, each with a Unix timestamp ('t') and the count of unique on-chain entities holding at least 1,000 BTC ('v'), representing a daily time series of large-holder entity counts.
