Finance APIs.
Finance APIs cover the money-adjacent lookups and checks an application needs — live exchange rates, IBAN and VAT verification, BIN lookups, invoice parsing. Rates and registries stay current on their side, not in a table you forgot to refresh.

Convert and Get Crypto Prices API
Crypto Prices Converter gives you live spot prices and conversion results for supported cryptocurrencies and fiat currencies. Send a quote currency and one or more symbols to get current prices back, or pass a source currency, target currency, and amount to calculate a conversion. The spot prices endpoint accepts vs as usd, eur, gbp, btc, or eth, plus an optional symbols query string. The response includes the requested vs, a source string, and a prices object keyed by symbol. Each symbol entry returns price, with optional change24h and marketCap values when available. The conversion endpoint takes required from and to query parameters, plus an optional amount. The response returns from, to, amount, result, usdPerFrom, and usdPerTo, which makes it useful for displaying exchange values or normalising balances across assets. Use Crypto Prices Converter when you need current pricing in a trading dashboard, a portfolio view, a checkout flow, or an internal finance tool that compares coin values without maintaining your own rate feed.
API ForgeVerifiedCrypto Market Sentiment Index API
Crypto Sentiment Index returns the current crypto market sentiment as a numeric value, a classification label, and a Unix timestamp in milliseconds. Send an optional limit query parameter to control how many recent entries you want back, up to 30. Use it when you need a lightweight signal for dashboards, trading bots, alerts, or market commentary. The response includes a source string and an entries array, so you can trace where the sentiment data came from and iterate over the latest readings without extra parsing. Each entry contains value from 0 to 100, classification, and timestamp. That makes it easy to compare the current reading with historical snapshots, threshold alerts, or other market indicators in your own app. If you need a compact sentiment feed for crypto products, Crypto Sentiment Index keeps the response focused on the fields that matter.
API ForgeVerifiedGet Global Crypto Market Overview API
Crypto Market Cap returns the global cryptocurrency market snapshot in a chosen quote currency. Send vs as usd, eur, gbp, btc, or eth, and get back the current market data in that denomination. The response includes source, vs, totalVolume, btcDominance, ethDominance, totalMarketCap, marketCapChange24h, and activeCryptocurrencies. Numeric fields may be null when the upstream source does not have a value available, so you can handle missing market data without guessing. Use Crypto Market Cap when you need to show a dashboard, drive portfolio analytics, or annotate a crypto summary with current dominance and capitalization figures. Because the output is already normalised around a single vs currency, it fits cleanly into charts, market overviews, and comparison views. It is a lightweight read-only endpoint for applications that need a fast global crypto market reference rather than per-asset pricing or exchange order books.
API ForgeVerifiedGet Historical Crypto Prices and Volume API
Crypto Price History returns historical price and volume data for a cryptocurrency symbol. Send a symbol, optionally set vs to usd, eur, gbp, btc, or eth, and choose a days window up to 365. The response includes the requested symbol, the quote currency in vs, the number of days, a source, and a points array. Each point in points contains a Unix timestamp in milliseconds (t), the price, and the traded volume at that time. That makes it easy to plot price charts, compare recent volatility, or backfill time-series data in your own dashboard or analytics pipeline. Use Crypto Price History when you need a compact market-history feed for a trading screen, portfolio tracker, alerting job, or crypto research workflow. The output is already structured for charting and downstream storage, without extra parsing.
