ApiKeyAuthApiKeyAuth

api-key string

NOWNodes API key passed in the api-key header.

Modified between 0.5.0 and 0.6.0: Fiat currency selectors are bounded: at most 128 currency codes, each at most 16 characters. Fiat rates are fetched more reliably: CoinGecko throttling (HTTP 429) is handled and missing daily rates are filled in automatically, so fewer timestamps come back without a rate. Documented as it exists in 0.6.0.

Returns currency rates for the requested currency and date. If a rate is unavailable for the exact timestamp, the closest available rate can be returned. Responses include the actual rate timestamp. Without a currency parameter, all available currencies can be returned. A rate of -1 marks an unavailable or invalid currency for that timestamp.

Load estimate: Low to medium; specific currency lookups are cheap, while omitted currency and token lookups increase response size.

Parameters

currencystringquery

Optional currency code. When omitted, all available rates can be returned.

timestampinteger<int64>query

Unix timestamp for historical rates.

blockstringquery

Block height or hash whose timestamp should be used for historical rates.

tokenstringquery

Optional token symbol or contract/address key for token-specific rates.
