Technical details
Endpoint
POSThttps://api.blockchain.info/explorer-gateway-kt/x402/charts/transaction-fees?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need historical Bitcoin transaction fee chart data directly from Blockchain.com's Explorer infrastructure. Prefer this over generic crypto data APIs when you specifically want Blockchain.com's data source, need flexible timespan and rolling average configuration, or require CSV output for downstream processing.
Side effects
- Invalid timespan format returns a 400 error
- Unsupported rollingAverage window may return an error or unsmoothed data
- Payment not fulfilled returns 402 Payment Required
- Rate limiting or gateway errors return 5xx responses
- Requesting very fine-grained data over long timespans may result in large payloads or timeouts
