Example prompt: What's the total amount of Bitcoin transaction fees collected in the latest reporting interval according to Blockchain.info?

## When to prefer this

Use this endpoint when you need a quick, low-cost lookup of the current total Bitcoin transaction fees as reported by Blockchain.info stats. Prefer it over building a direct Blockchain.info integration when you want a pay-per-call model via x402 without managing API keys. Best suited for dashboards, monitoring pipelines, or agents that need a single on-chain fee metric rather than full blockchain analytics.

## Known failure modes

- Blockchain.info upstream API unavailable — proxy returns an error or empty response
- Stale data if Blockchain.info has not updated its stats for the current interval
- No query parameters supported, so no ability to filter by time range or denomination
- Raw value returned without units or timestamp context, requiring caller interpretation

## How this service works

## Output

A raw numeric value representing the total Bitcoin transaction fees (in satoshis or BTC, as returned by Blockchain.info) collected over the most recent reporting interval, passed through directly from the upstream stats API.
