What authentication does the Barchart OnDemand API use?

Barchart OnDemand uses an API key passed as the apikey query parameter on every request. When called through Jentic, the key is stored encrypted in your Jentic One instance and injected at execution time so it never enters the agent's context.

Can I get options chains with the Barchart API?

Yes. Call GET /getEquityOptions.json with the underlying symbol and optional expiration filters. The response includes calls and puts with strike, expiration, bid, ask, last, volume, and open interest.

What are the rate limits for the Barchart OnDemand API?

Barchart does not document a request rate limit, and neither its own OpenAPI document nor the specification behind this page declares one, so treat throttling as undefined rather than absent. What Barchart does say is commercial: it prices market data by usage and packages it from small to enterprise. For heavy polling, prefer the settled endpoints /getQuoteEod.json and /getClosePrice.json and cache historical pulls from /getHistory.json locally.

Is there a Barchart MCP server?

You don't need an MCP server to give your agent Barchart OnDemand. Jentic connects it directly from the API Directory: import Barchart, store your apikey once, and your agent can pull quotes, history, options chains, fundamentals, and ratings, with no extra tool definitions loaded into its context.

How do I get a stock quote through Jentic?

Install Jentic One on its own machine, run `jentic register` on the machine your agent runs on, then import the Barchart OnDemand Market Data API from the API Directory and store your apikey once. Your agent searches by intent for 'get the latest stock quote', loads the schema for GET /getQuote.json, and executes it with the symbols parameter. Jentic injects the apikey query parameter and returns the price, change, and volume fields the agent needs.

Does Barchart OnDemand expose cryptocurrency data?

Yes. /getCrypto.json returns spot prices for cryptocurrencies and /getCryptoHistory.json returns historical time-series. Coverage focuses on major coins and the data complements equity quotes when an agent needs cross-asset views.

Can I limit what my agent is allowed to do with the Barchart OnDemand Market Data API?

Yes. Because you run Jentic One yourself, you decide which Barchart operations your agent may call, and your own rules govern access. Barchart passes symbols and time ranges as query parameters rather than in the URL path, so you scope the agent to just the operations it needs, such as GET /getQuote.json for quotes or GET /getHistory.json for historical prices. Options, ratings, and crypto endpoints like /getEquityOptions.json, /getRatings.json, and /getCrypto.json stay out of reach unless you add them, and the encrypted API key is injected at execution time so it never enters the agent's context.
