}About the farside.co.uk API
The Farside ETF Flows API exposes 6 endpoints covering daily inflow and outflow data for all US spot Bitcoin, Ethereum, and Solana ETFs, denominated in US$m. The get_bitcoin_etf_flows_all endpoint returns a complete record from January 2024 onward, with per-ticker columns for IBIT, FBTC, BITB, ARKB, and others alongside running totals. Summary statistics — fees, averages, maximums, and minimums — are included across every flow endpoint.
Bitcoin ETF Flow Data
Two endpoints cover US spot Bitcoin ETFs: get_bitcoin_etf_flows_recent for the latest trading days and get_bitcoin_etf_flows_all for the full history from January 2024 to present. Both return a data array of daily records keyed by Date, with individual columns for each ticker (IBIT, FBTC, BITB, ARKB, BTCO, EZBC, BRRR, HODL, BTCW) and a Total field per row. A summary object accompanies each response with Fee, Total, Average, Maximum, and Minimum breakdowns per ticker, making it straightforward to compare fund-level accumulation or draw down across the cohort.
Ethereum and Solana ETF Flow Data
get_ethereum_etf_flows_recent and get_ethereum_etf_flows_all mirror the Bitcoin structure for US spot Ethereum ETFs (ETHA, ETHB, FETH, ETHW, TETH, ETHV, QETH, EZET, ETHE), with history starting from July 2024. The summary objects for Ethereum endpoints add Staking and Seed fields per ticker — relevant distinctions given product-level differences among issuers. get_solana_etf_flows covers the Solana cohort (BSOL, VSOL, FSOL, TSOL, SOEZ, GSOL) with the same Fee, Staking, Seed, and Total summary structure. All flow values are denominated in US$m.
Farside Equity Fund Info
get_fund_info returns static and periodically updated metadata for the Farside Equity Fund itself: current NAV (with date embedded in the key name), launch date and price, FCA host firm, fund auditor, fund registration authority, fund administrator, and investment advisor details including the director's name and regulator. This endpoint is useful for anyone building dashboards that reference fund-of-record information alongside the ETF flow data.
- Chart daily net flows per Bitcoin ETF ticker to visualize institutional allocation shifts over time
- Compare total cumulative inflows across Ethereum ETF issuers using the
Totalsummary field - Screen for outlier trading days using
MaximumandMinimumvalues from the Bitcoin ETF summary object - Track Solana ETF adoption by monitoring the
Totalcolumn across daily records since launch - Display Farside Equity Fund NAV and service-provider details on a crypto fund information dashboard
- Correlate ETF flow data with price movements by joining dated flow records with external price feeds
- Monitor staking and seed capital exposure across Ethereum ETF products using the
StakingandSeedsummary fields
| Tier | Price | Credits/month | Rate limit |
|---|---|---|---|
| Free | $0/mo | 100 | 5 req/min |
| Hobby | $30/mo | 1,000 | 20 req/min |
| Developer | $100/mo | 5,000 | 250 req/min |
One credit = one API call regardless of which marketplace API you call. Exceeding the rate limit returns a 429 response. Authenticate with the X-API-Key header.
Does farside.co.uk offer an official developer API?+
What does the `summary` object contain, and does it differ across endpoints?+
summary object keyed by ticker. Bitcoin endpoints include Fee, Total, Average, Maximum, and Minimum. Ethereum and Solana endpoints extend this with Staking and Seed fields, reflecting product-level differences among those ETF issuers. The all-history Bitcoin endpoint omits Fee from its summary, returning only Total, Average, Maximum, and Minimum.How far back does the historical data go?+
get_bitcoin_etf_flows_all covers daily records from January 2024 onward, which aligns with the US spot Bitcoin ETF launch window. get_ethereum_etf_flows_all starts from July 2024, when US spot Ethereum ETFs began trading. The Solana endpoint covers data from the point Solana ETF products appeared on Farside's tracker. Exact start dates are reflected in the earliest Date value in each data array.Does the API provide on-chain or AUM data, not just flows?+
Can I filter flow data by a specific ticker or date range?+
data array. If you need a filtered endpoint, you can fork the API on Parse and revise it to add query parameters that subset the response.
