# Glassnode Sending Addresses Count

> Glassnode Sending Addresses Count is a paid API for AI agents from x402.glassnode.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns the number of unique on-chain addresses that were active as a sender of funds for a given asset and time interval.

## 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-sending-addresses-count-e386d96a
```

Example prompt: How many unique sending addresses were active on Bitcoin over the past 24 hours? Pull the daily Glassnode data for BTC in JSON format.

## When to prefer this

Use this endpoint when you need on-chain network activity data specifically about sender participation — how many unique wallets initiated transactions on a given blockchain. Prefer this over total transaction count endpoints when you want to measure the breadth of participation rather than volume. Ideal for trend analysis of network growth or decline in active senders.

## Known failure modes

- Missing required asset symbol 'a' parameter returns 400 error
- Invalid interval value not in enum returns 400 error
- Unsupported network identifier returns 400 error
- Payment not processed or insufficient USDC balance returns 402 error
- Rate limiting or quota exceeded returns 429 error
- Metric not available for the requested asset/network combination returns 404 or empty array

## How this service works

Number of Sending Addresses — The number of unique addresses that were active as a sender of funds. Data by Glassnode.

## Output

Returns a time-series array of objects, each containing a Unix timestamp ('t') and the count of unique sending addresses ('v') for the requested asset and interval. Covers major blockchains including BTC, ETH, SOL, and others.
