FAQ
Are google_trend_percent and tweet_count always returned?
Not necessarily. These two are reserved fields that may not be returned; as of 2026-10-20, no data contains them. In your code, check whether the fields exist first, do not rely on them, and do not treat their absence as 0.
What format is date_string in?
YYYY-MM-DD, e.g., 2010-07-17. This endpoint has no millisecond timestamp field; Bitcoin AHR999 Indicator in the same section uses YYYY/MM/DD, so unify the formats before merging data.
Can the bubble index be negative?
Yes. Early data is negative (e.g., -29.6); a negative value does not mean the price is negative.
Can I query data for only a specific time period?
No. This endpoint has no parameters and always returns the full history (the response is about 940 KB); if you need a specific period, filter locally by date_string. We recommend caching the result and refreshing it as needed; there is no need to request it frequently.
Learn More: Bitcoin Bubble Index
What Is the Bitcoin Bubble Index?
The Bitcoin Bubble Index uses a single value to measure the degree of “bubble” in the Bitcoin price. Alongside the index, this endpoint also returns the price, mining difficulty, transaction count and sending address count for each day, making it easy to compare the index with the price and basic network data.
What Do Mining Difficulty, Transaction Count and Sending Address Count Represent?
Mining difficulty reflects how intense the competition for hash power is across the network: the higher the hash power, the higher the difficulty; transaction count is the number of on-chain transactions on that day; sending address count is the number of addresses that sent Bitcoin on that day. They are all basic data for measuring the scale and usage of the Bitcoin network.
Can the Bubble Index Alone Be Used to Identify a Top?
Not recommended. Any single indicator can fail; the bubble index is better used as one reference, together with other cycle indicators such as Bull Market Peak Indicators.
