Version History
- Responses are now provided in TOON (Token-Oriented Object Notation) format instead of JSON, saving ~40% tokens. - Added instructions for decoding TOON responses using the @toon-format/toon package. - Updated sample code and usage sections to demonstrate decoding and handling TOON data. - Clarified that all API consumers must decode responses before use.
What This Skill Does
Fetches real-time stock quotes and market data from the Stock Prices API using ticker symbols. Responses arrive in TOON format, a compact encoding that uses roughly 40% fewer tokens than JSON, decoded with the @toon-format/toon package. Supports up to 50 symbols per request, including pre-market pricing and day-range data.
The TOON response format cuts token usage by ~40% compared to JSON, which lowers cost and latency when feeding market data into LLM prompts or streaming pipelines.
When to use it
- Checking NVDA's price before placing an options order
- Pulling quotes for 20 holdings at once to calculate portfolio value
- Reviewing pre-market data for volatile stocks before the open
- Summarizing which stocks in a watchlist are up or down today
- Setting up a price-change alert when a ticker crosses a threshold
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: What are the current prices and daily changes for AAPL, GOOGL, and MSFT?
- 1Send GET request to https://stock-prices.on99.app/quotes?symbols=AAPL,GOOGL,MSFT
- 2Decode the TOON-format response body using decode() from @toon-format/toon
- 3Extract currentPrice, change, and percentChange for each quote object
- 4Format results into a price summary per symbol
AAPL: $182.50 (+1.2%), GOOGL: $175.30 (-0.4%), MSFT: $415.80 (+0.8%)
