How this service works
Paid AI-agent access to Blockchain.com Explorer API
Output
Returns a time series of median Bitcoin transaction confirmation times, either as structured JSON (with optional metadata) or raw CSV. JSON responses include timestamps paired with median confirmation time values in minutes, with optional chart metadata. CSV responses contain timestamp and value columns without metadata. Data can be sampled to reduce point density and smoothed via a configurable rolling average window.
Example use cases
