Spot Bitcoin ETF Onchain Flows [BTC]
Daily on-chain Bitcoin flows for spot ETFs that have publicly known wallet addresses
Request format
curl -X GET "https://newhedge.io/api/v2/metrics/spot-bitcoin-etf-onchain-flows/METRIC_NAME?api_token=YOUR_TOKEN"api_token (required) — 24 character token.
resolution (optional) — 1d only for the metrics on this chart. A finer value is refused, never served as 1d: 401 when the token is not entitled to finer buckets, 400 when it is entitled and the metric does not ingest that bucket; see Resolutions.
before (optional) — exclusive cursor, returns observations older than this timestamp_ms. Works on every resolution.
limit (optional) — the most recent N observations, maximum 5000. Finer resolutions page by default (2500); a 1d request returns the whole series unless you send limit or before.
before and limit narrow a time series. A response with no single time axis, such as a hash keyed by venue or a labelled snapshot table, has nothing to cut on. It is returned whole, and both parameters are ignored rather than rejected.
A before that is not a positive epoch-millisecond timestamp is a 400. It is the one paging value we reject rather than ignore, because a page size has a sensible default and a cursor does not.
include (optional) — definition wraps the response as {"definition": …, "data": …} and returns the record shown under each metric; see Definitions. Any other value is a 400.
:metric_name — one of the metric names listed below.
200 with JSON payload, 400 for an unknown include value, 401 for missing/invalid token, 404 for missing resources. A 404 for a metric withdrawn on purpose adds withdrawn, withdrawn_on and reason, for example {"error":"Metric not found","withdrawn":true,"withdrawn_on":"2026-09-07","reason":"The venue's public feed reports insurance-fund settlements, not liquidation orders."}; a removed chart can add successor.
Plan and quota refusals keep these statuses and error texts and add code, required_plan, current_plan, feature, upgrade_url, limit and resets_at where they apply. A Pro token whose history window removed points also gets the X-Newhedge-History-Truncated headers, and for a Pro token X-Newhedge-Available-From is the start of the window. See Errors and plan limits.
Metrics
Each metric is fetched independently. Responses are trimmed samples to show structure.
