Market data APIs for pricing and valuation tools
Build jewelry melt-value calculators, precious-metal pricing tools, FX converters, quote estimators, and embedded valuation widgets with current prices and historical market data.
How it works
Current market data in, useful customer answers out.
Pricing tools often need a small number of reliable market inputs rather than a full trading interface. Retrieve the relevant prices, apply the product's calculation rules, and present the result in a form users can immediately understand.

- Current quotes
- Historical OHLCV
- Latest prices
Application logic
- Weights and quantities

Use cases
What teams build with a few market inputs.
FX and currency converters
Use current foreign-exchange rates to power international pricing, currency conversion, travel tools, payment estimates, and cross-border calculators.
Quote and cost estimators
Combine current market prices with quantities, costs, margins, or other application rules to produce transparent customer estimates.
Embedded valuation widgets
Add market-linked values to product pages, dashboards, marketplaces, portfolio tools, and other customer-facing applications.
Capabilities
Market data that fits focused pricing workflows.
Current market prices
Retrieve current commodity, FX, crypto, or stock prices for calculators, converters, valuation interfaces, and customer-facing estimates.
Historical context
Add charts, comparisons, and prior-period context using historical OHLCV where supported by the selected market and plan.
Predictable data usage
Retrieve the required prices at a cadence appropriate to the application rather than generating an upstream request for every visitor interaction.
Flexible calculation logic
Use market prices as defaults while allowing the application to apply quantities, weights, purities, currencies, margins, or user-entered assumptions.

FAQ
Pricing tools and calculators: common questions
Can I use SiftingIO for a jewelry or precious-metal calculator?
Yes. Supported commodity identifiers include gold, silver, platinum, energy, industrial metals, and agricultural reference series. Applications can retrieve the required prices and apply their own weight, purity, quantity, or valuation rules.
Can users enter their own assumed market price?
Yes. An application can use the current market value as the default while allowing users to enter a custom price for scenario analysis. The calculation behavior remains under the application's control.
Can I add historical charts to a calculator?
Yes, where historical OHLCV is available for the selected market and plan. Historical data can support trend charts, comparisons, and prior-period context.
Should a public calculator request the API separately for every visitor?
Usually not. A public tool can retrieve the required prices securely and reuse them for an appropriate period based on its refresh requirements. The exact setup depends on the product and traffic pattern.
Can SiftingIO be credited as the data provider?
Yes. A concise attribution such as “Market data powered by SiftingIO” may link to the relevant SiftingIO product page.
Which plan is appropriate for a small calculator?
The appropriate plan depends on the number of symbols, refresh schedule, monthly API usage, display requirements, and commercial use. The Free plan can be used for evaluation before reviewing whether a paid plan is needed.
