# Glassnode Bridges Withdrawals By Chain

> Glassnode Bridges Withdrawals By Chain 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Returns the total USD value withdrawn from Ethereum bridge smart contracts, broken out per destination chain, showing capital flowing back into Ethereum from target blockchains.

## 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-bridges-withdrawals-by-chain-a3286720
```

Example prompt: Can you pull the Glassnode bridge withdrawals by chain metric for ETH in USD for the last 24 hours, so I can see how much value is flowing back into Ethereum from different blockchains?

## When to prefer this

Use this endpoint when you need chain-specific breakdown of bridge withdrawal flows (capital returning to Ethereum from L2s/sidechains) with USD denomination, sourced from Glassnode's on-chain data. Prefer this over generic bridge trackers when you need structured time-series data per destination chain with a 24h resolution and reliable institutional-grade blockchain analytics.

## Known failure modes

- Missing required 'a' parameter (asset symbol) returns 400 error
- Invalid asset symbol returns 422 or empty result
- Payment not included or insufficient USDC triggers 402 Payment Required
- Unsupported interval or currency enum value returns validation error
- Rate limiting or upstream Glassnode data unavailability returns 503

## How this service works

Bridges Withdrawals By Chain — The total USD value withdrawn from bridge smart contracts on Ethereum and therefore flowing back into Ethereum and out of the target blockchains, broken out per destination chain. Data by Glassnode.

## Output

A time-series array of objects, each with a timestamp (t) and an object (o) containing the USD value of bridge withdrawals broken down by destination chain, showing capital leaving L2s and other chains back to Ethereum.
