Example prompt: What is Bitcoin's current adjusted circulating supply according to Glassnode — I want the native BTC amount with lost coins excluded, in JSON format for a 24-hour interval?

## When to prefer this

Use this endpoint when you need a more accurate measure of Bitcoin's effective supply by removing estimated lost coins from the raw circulating supply — particularly useful for valuation models, stock-to-flow calculations, or on-chain analysis that requires a realistic supply figure. Prefer this over raw circulating supply endpoints when building scarcity metrics or evaluating true liquid supply.

## Known failure modes

- Missing required 'a' query parameter (asset symbol) returns a 400 error
- Unsupported asset symbol (non-BTC) returns a validation error since only BTC is currently supported
- Payment not provided or insufficient USDC balance triggers a 402 Payment Required response
- Invalid interval or format enum values return a 400 bad request
- Rate limiting or quota exhaustion may return a 429 error
