How this service works
Paid AI-agent access to Blockchain.com Explorer API
Output
Returns structured JSON (or CSV) containing historical Bitcoin market price data points with timestamps and price values. JSON mode includes optional metadata about the chart. Rolling average smoothing and sampling are applied based on parameters. Covers the requested timespan (e.g. 24h, 7d, 1y, 3y) at the configured granularity.
Example use cases
Long-term BTC price trend analysis
“Can you get me Bitcoin's market price history from Blockchain.com for the past 3 years with a 24-hour rolling average so I can spot long-term trends?”
Recent Bitcoin price snapshot
“Fetch the last 7 days of Bitcoin market price data from Blockchain.com's explorer in JSON format with sampling enabled so I can see recent price movement.”
CSV export for spreadsheet modeling
“I need Bitcoin's market price data for the past year from Blockchain.com exported as CSV with a 24h rolling average — I'm going to load it into a spreadsheet.”

Endpoint

Use this endpoint when you need historical Bitcoin market price data specifically from Blockchain.com's Explorer, with built-in rolling average smoothing and flexible timespan selection. Prefer this over generic crypto APIs when you want Blockchain.com's proprietary market price series with sampling and averaging built in, and when you need both JSON and CSV output options in a single endpoint.
