## 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-absolute-via-x402-00e36197
```

Example prompt: Pull me Glassnode's daily data on total Ethereum gas consumed by NFT transactions — including OpenSea and Blur — in JSON format for ETH using native currency units.

## When to prefer this

Use this endpoint when you need authoritative on-chain Ethereum gas consumption data specifically attributed to NFT activity, sourced from Glassnode's institutional-grade blockchain analytics. Prefer this over generic blockchain explorers when you need clean time-series data covering both NFT token standards (ERC721/ERC1155) and major NFT marketplaces in a single unified metric.

## Known failure modes

- Missing required query param 'a=ETH' returns 400 or empty response
- Unsupported interval or format enum value causes validation error
- Payment not processed (402) if USDC payment header is missing or insufficient
- Rate limiting if too many calls within a short window
- Data unavailable for very recent timestamps if indexing is delayed

## How this service works

Gas Usage by NFTs (Absolute) — The total amount of Ethereum network gas consumed by transactions interacting with non-fungible tokens. This category includes both NFT token contract standards (ERC721, ERC1155) and NFT marketplaces (OpenSea, Blur, LooksRare, Rarible, SuperRare) used to trade them. Data by Glassnode.

## Output

Returns a time-series array of objects, each with a Unix timestamp (t) and a nested object (o) containing the total gas consumed by NFT-related transactions on Ethereum for that time period, denominated in native gas units.
