How this service works
Paid AI-agent access to Blockchain.com Explorer API
Output
Returns a time-series dataset of unique Bitcoin address counts, with timestamps and values, optionally smoothed by a rolling average window. In JSON mode includes structured metadata; in CSV mode returns raw two-column data (timestamp, value). Data may be sampled to reduce volume.
Example use cases
Bitcoin adoption trend research
“Show me the historical trend in unique Bitcoin addresses over the past year using a 24-hour rolling average — I want to see how network adoption has changed.”
Crypto market analysis dashboard
“Get me the unique Bitcoin address chart data for the last 7 days in JSON format from Blockchain.com so I can compare it against price movements.”
On-chain network activity monitoring
“Fetch the number of unique Bitcoin addresses used over the past 3 years with metadata included, so I can track long-term network growth.”

Endpoint
POSThttps://api.blockchain.info/explorer-gateway-kt/x402/charts/n-unique-addresses?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official Blockchain.com data on unique Bitcoin address activity over time, especially for adoption trend analysis, network growth charting, or on-chain analytics dashboards. Prefer it over generic crypto data APIs when you specifically want Blockchain.com's explorer-grade, paid-grade reliable data with flexible timespan and rolling average options.
Side effects
- Invalid timespan format returns an error or empty dataset
- Unsupported format value (not 'json' or 'csv') causes a 400 error
- Payment failure via x402 protocol results in 402 Payment Required
- Network timeout for very large timespans with sampling disabled
- Empty result if the rolling average window exceeds the requested timespan
