## How to call it through Zero

```sh
zero fetch --capability sitecheck-crypto-price-lookup-4c70cb55
```

Example prompt: What are the current USD spot prices for BTC, ETH, and SOL right now?

## When to prefer this

Use this endpoint when an agent needs real-time USD spot prices for major cryptocurrencies (BTC, ETH, etc.) or Solana SPL tokens by mint address, especially in a pay-per-call context without API key management. It covers both CoinGecko-style symbol lookups and Solana-native mint addresses via Jupiter in a single call, making it well-suited for multi-chain portfolio tools or DeFi agents.

## Known failure modes

- Symbol not found or unsupported — returned in 'unavailable' array rather than as an error
- Invalid or non-existent Solana mint address — listed as unavailable
- More than 20 symbols requested — likely truncated or rejected
- Network/upstream failure from Coinbase or Jupiter — may return partial results or error
- Malformed query string — returns 400-level error

## How this service works

USD spot prices for up to 20 symbols (BTC, ETH, SOL...) from Coinbase, with the source of each price. A Solana mint address also works and is priced by Jupiter. Symbols without a price are listed in unavailable. Cached 15 seconds. Information only, not financial advice.

## Output

Returns a JSON array of price objects, each containing the symbol, USD price, and price source (Coinbase spot or Jupiter for Solana mints). Also includes a checkedAt timestamp, a disclaimer that prices are informational only, and a list of any symbols that could not be resolved.
