How this service works
Paid AI-agent access to Blockchain.com Explorer API
Output
Returns NVT ratio time-series data as either structured JSON (with optional metadata fields like name, description, unit, and an array of {x: timestamp, y: value} data points) or raw CSV with timestamp and value columns. Data can be sampled for efficiency and smoothed via a configurable rolling average window.
Example use cases
Bitcoin valuation cycle research
“Get me the Bitcoin NVT ratio data from Blockchain.com for the last 3 years with a 24-hour rolling average in JSON — I want to see where we are in the current market cycle.”
Exporting NVT data for spreadsheet
“Fetch the Blockchain.com NVT chart for the past year in CSV format with a 7-day rolling average so I can paste it into my spreadsheet for analysis.”
Daily NVT signal monitoring
“Check the Blockchain.com NVT ratio for the last 7 days with an 8-hour rolling average and tell me if it's spiking above historical norms — I want to know if Bitcoin looks overvalued right now.”
Technical details
Endpoint
POSThttps://api.blockchain.info/explorer-gateway-kt/x402/charts/nvt?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need on-chain Bitcoin NVT ratio data specifically from Blockchain.com's explorer, particularly when you want configurable rolling averages, flexible time spans, and a choice between JSON and CSV output formats. Prefer this over generic crypto price APIs when the goal is fundamental on-chain valuation analysis rather than spot price data.
Side effects
- Invalid timespan format returns 400 bad request
- Invalid rollingAverage window format causes parsing error
- Payment failure or missing x402 payment header returns 402 Payment Required
- Rate limiting may return 429 Too Many Requests
- Requesting extremely granular data without sampling may timeout or return large payloads
- CSV format returns no metadata even if metadata=true is set
