Data API
Free live endpoints live now
No key, no signup. Same numbers the dashboards render, refreshed continuously, cached ~30 s at the edge:
GET https://basintwo.com/api/chain/doge # live DOGE metrics
GET https://basintwo.com/api/chain/btc # live BTC metrics, from our own synced node
GET https://basintwo.com/api/nodes/ltc # node liveness receipts (also btc, doge)
Please cache on your side and keep it civil — these are provided as-is for light use. If you are building on them, tell us via platform@basintwo.com and we won't break you silently.
Historical archive endpoints API plan — launching soon
Keyed access to the first-party archive: per-block fee-rate percentiles, fees, sizes and subsidies for every canonical block we have validated (coverage). Authentication is a bearer key; usage is metered per UTC day.
GET /api/v1/chains # per-chain coverage summary
GET /api/v1/chain/{btc|ltc|doge} # live metrics, same shape as the free feed
GET /api/v1/{chain}/blocks?from_height=&to_height=&limit= # per-block rows incl. feerate percentiles
GET /api/v1/{chain}/fees/daily?from_day=&to_day= # daily aggregates
Every response carries an envelope with your usage: {"ok":true,"data":…,"meta":{"usage_today":…,"daily_cap":100000,"plan":"api","as_of":…}}. Caps return HTTP 429 with retry_after_secs — no silent throttling. The plan is $49/mo with 100,000 requests/day; card and Bitcoin payments both land shortly — the pricing page has the honest state and a demand counter.
Ground rules
The data is computed by our own full nodes and republished nowhere else — if you publish work built on it, cite the series start dates from /data so your readers can verify. Free daily CSV downloads of the same series live there too. Not financial advice; the free feeds carry no uptime commitment — the paid tier's terms will be published with the tier itself.
