Example prompt: Can you pull the Glassnode ETH burned supply data for me at a weekly interval in native ETH units, in JSON format?

## When to prefer this

Use this endpoint when you need on-chain Ethereum supply reduction data specifically tied to the EIP-1559 fee burn mechanism, sourced from Glassnode's institutional-grade blockchain analytics. Prefer this over general crypto price APIs when the user needs cumulative burned supply figures rather than price or market cap data.

## Known failure modes

- Missing required asset parameter 'a=ETH' returns a 400 or validation error
- Invalid interval value returns an error (only 24h, 1w, 1month supported)
- Payment not sent or insufficient USDC triggers a 402 Payment Required response
- Invalid currency or format enum value causes a query rejection
- Service unavailable or Glassnode data outage returns 5xx error

## How this service works

Burned Supply — Burned Supply is the cumulative sum of ETH destroyed by the EIP-1559 base-fee mechanism since the London Hard Fork activated it. Data by Glassnode.

## Output

An array of timestamped data points, each containing a Unix timestamp (t) and a numeric value (v) representing the cumulative ETH burned by the EIP-1559 base-fee mechanism at that point in time, returned in JSON or CSV format.
