# skills.bankofuniverse.org

Bank of Universe is a market data provider exposing single-shot price lookup endpoints for major cryptocurrencies. It currently serves agents that need a quick, current spot price for ETH or BTC without requiring a streaming connection or historical dataset. The host is narrow in scope: two assets, two endpoints, no configuration required.

## When to use this host

Use this host when an agent needs a simple, no-input current spot price for ETH or BTC in USD. It is not suitable for historical price data, OHLCV candles, streaming price feeds, or any asset other than ETH and BTC (despite supportedSymbols listing others, each endpoint is asset-specific). For multi-asset price feeds, historical data, or tokens beyond ETH/BTC, route to a broader market data provider such as CoinGecko, CoinMarketCap, or a full exchange API.

## Capabilities

### Crypto Spot Price Feeds

Provides current spot prices for ETH and BTC in USD, each with a millisecond-precision timestamp, suitable for point-in-time valuation, trading decisions, or display.

- **`fetch-eth-spot-price`** — Returns the current ETH spot price in USD with a millisecond-precision timestamp from the Bank of Universe market data feed.
- **`fetch-btc-price`** — Returns the latest Bitcoin (BTC) market price as a numeric value with a millisecond-precision timestamp from a real-time feed.

## Workflows

### ETH/BTC Ratio Calculation

*Use when an agent needs to compute the current ETH-to-BTC price ratio or compare the two asset prices at the same point in time.*

1. **`fetch-eth-spot-price`** — Retrieve the current ETH spot price in USD with timestamp.
2. **`fetch-btc-price`** — Retrieve the current BTC spot price in USD with timestamp, then divide ETH price by BTC price to derive the ETH/BTC ratio.

## Skill reference

### `fetch-eth-spot-price`

**Ethereum Price Feed** — Returns the current ETH spot price in USD with a millisecond-precision timestamp from the Bank of Universe market data feed.

*Use when:* Use when an agent needs the current Ethereum spot price in USD for trading decisions, portfolio valuation, or market analysis.

*Not for:* Do not use for historical price data or price feeds for tokens other than ETH (though BTC, USDC, USDT, TRX, BNB are listed as supported symbols, this endpoint is scoped to ETH).

**Returns:** Returns a JSON object with symbol ETH, a supportedSymbols array, the current USD spot price as a decimal, and a millisecond Unix timestamp.

**Example:** `GET https://skills.bankofuniverse.org/cos/crypto/price/ETH`

### `fetch-btc-price`

**Bitcoin Price Feed** — Returns the latest Bitcoin (BTC) market price as a numeric value with a millisecond-precision timestamp from a real-time feed.

*Use when:* Use when an agent needs the current BTC spot price for display, calculation, or analytics and requires a single-shot price lookup rather than a streaming feed.

*Not for:* Do not use for non-BTC asset prices; the endpoint is BTC-specific. Do not use for historical price data or streaming price updates.

**Returns:** Returns a JSON object with symbol 'BTC', a numeric USD price, a list of supported symbols, and a millisecond-precision Unix timestamp.

**Example:** `GET https://skills.bankofuniverse.org/cos/crypto/price/BTC`
