# Glassnode NFT Gas Usage Share (Relative) — Ethereum

> Glassnode NFT Gas Usage Share (Relative) — Ethereum is a paid API for AI agents from x402.glassnode.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-16).

Returns the share of total Ethereum gas consumed by NFT-related transactions (ERC-721, ERC-1155 contracts and major NFT marketplaces like OpenSea, Blur, LooksRare, Rarible, SuperRare) as a relative percentage.

## 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-nft-gas-usage-share-relative-ethereum-b97c07e5
```

Example prompt: What share of Ethereum's total gas usage is currently being consumed by NFT transactions and marketplaces like OpenSea and Blur? Pull the latest 24h Glassnode data for ETH in JSON format.

## When to prefer this

Use this endpoint when you need on-chain, blockchain-native data specifically measuring NFT ecosystem gas demand relative to total Ethereum gas — especially when tracking NFT market activity cycles, comparing NFT vs DeFi network usage, or analyzing how NFT marketplace activity (OpenSea, Blur, LooksRare) impacts Ethereum block space utilization. Prefer this over general fee endpoints when the NFT-specific relative share (not absolute gas) is the key metric.

## Known failure modes

- Missing required 'a' query parameter (must be 'ETH') returns 400 Bad Request
- Unsupported interval or format enum value returns validation error
- Payment not provided or insufficient USDC results in 402 Payment Required
- Rate limiting or quota exceeded returns 429 Too Many Requests
- Glassnode data pipeline delay may cause stale or missing recent data points

## How this service works

Gas Usage by NFTs (Relative) — The share of Ethereum gas consumed by transactions interacting with non-fungible tokens. The category includes both NFT token-contract standards (ERC-721, ERC-1155) and the NFT marketplaces (OpenSea, Blur, LooksRare, Rarible, SuperRare) where those tokens trade. Data by Glassnode.

## Output

Returns a time-series array of objects, each containing a Unix timestamp (t) and an object (o) with the relative share of Ethereum gas consumed by NFT-related transactions (ERC-721, ERC-1155 token contracts and major NFT marketplaces) expressed as a fraction or percentage of total gas used, at 24h resolution.
