Get compact block filters.

GET

https://qtum-blockbook.nownodes.io/api/v2/block-filters

Authorizations

ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Returns compact block filters for the configured script type. Provide either lastN or a from/to range. When to is omitted for a range, the current best height is used.

Compact block filters are not currently enabled on the NOWNodes Qtum endpoint. Requests succeed and return the requested heights with their block hashes, but each filter value comes back empty. Send scriptType empty, as no script type is configured.

Load estimate: High for wide ranges; work and payload grow linearly with the number of requested filters.

Parameters

scriptTypestringrequiredquery

Script type used for block filters. No script type is configured on the NOWNodes Qtum endpoint, so send this parameter empty.

lastNinteger>= 1query

Return filters for the last N blocks.

frominteger>= 0query

First block height in the requested range.

tointeger>= 0query

Last block height in the requested range. Defaults to the current best height when omitted.

Response

200OK

Block filters keyed by block height.
