goldprice.devThese silver price APIs serve developers building silver displays, converters and historical charts. Spot quotes and a daily benchmark price are different inputs, and a provider's currency total does not guarantee every silver pair. The comparison separates quote coverage, historical access and plan limits, including where documentation does not establish a start date or exact series depth.
The list is ranked by fit for silver pricing, weighing spot access, currency coverage, history and integration options. goldprice.dev publishes this page and is listed first. Narwhal API is the sibling broader data API for commodities, FX, economics and calendars. Check the silver pair and price series rather than relying on a provider's overall metals catalog.

Choose the silver series and quote currency first, then compare freshness, history windows and request costs. Check conversion endpoints separately from native quotes. For benchmark research, confirm the silver-specific date range rather than borrowing a gold archive's start date. goldprice.dev and Narwhal API are owned and operated by Nusantara Ventures, LLC.
