## How to call it through Zero

```

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call access to Glassnode's mean transaction fee metric for major blockchains. Prefer this over median fees when you want the arithmetic average (sensitive to fee spikes), and over total fees when you want a per-transaction normalized view. Ideal for on-chain analytics, fee monitoring dashboards, or agent workflows that need fresh blockchain fee data without a monthly Glassnode subscription.

## Known failure modes

- Missing required 'a' (asset) query parameter returns validation error
- Invalid asset symbol not in enum (BNB, BTC, DOGE, ETH, SOL, TON, TRX, XRP) returns error
- Invalid interval or currency enum value returns error
- Payment of $0.05 USDC not received results in 402 Payment Required
- Network parameter not applicable to all assets may return empty or error
- Rate limiting or upstream Glassnode data unavailability may cause 5xx errors
