ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Modified between 0.5.0 and 0.6.0: page and pageSize are now validated: page is capped at 1,000,000, and when page × pageSize exceeds 100,000 the page is clamped to the last allowed one. Negative or non-numeric values fall back to the defaults. from and to are bounded to non-negative block heights. XPUB/descriptor scans are bounded: gap is capped at 10,000, a descriptor may list at most 10 change indexes, and a descriptor whose total derivation scan exceeds the server limit is rejected with an error. Documented as it exists in 0.6.0.

Not available on this endpoint: the request returns HTTP 500 with {"error":"Internal server error"}.

Returns balances and transactions of an XPUB or output descriptor for Bitcoin-type coins. Transactions are sorted by block height with newest blocks first. URL-encode descriptors before placing them after /xpub/.

Blockbook expects XPUBs at level 3 of the derivation path, for example m/purpose'/coin_type'/account'. It derives the remaining change/address_index path. The BIP scheme is inferred from the XPUB prefix; unknown prefixes default to BIP44.

Supported descriptors are pkh(xpub), sh(wpkh(xpub)), wpkh(xpub), and tr(xpub). Descriptors can include origin paths and change selectors such as <0;1> or {0,1}; when change is omitted, Blockbook defaults to <0;1>.

Note: usedTokens always reports the total number of used addresses for the XPUB, regardless of the tokens query filter.

Load estimate: High for broad accounts; grows with derived addresses, gap, used address count, pageSize, transaction history, token rows, and protocol enrichment.
