OptionAPI.com is an educational options data and developer-reference site. It brings together market-specific guides, full-length articles and downloadable synthetic records. It is not a brokerage, exchange or live quote service.
Start with stock, equity, index, futures, Bitcoin, Solana, ETF, bond and interest-rate options. Separate references cover calls, puts, trader workflows and model-assisted research. Topic coverage is educational, not a claim of live instrument availability.
No. All sample JSON figures are synthetic, and chart figures in the artwork are decorative. Each example identifies its purpose. No account is connected and no market order can be submitted on this website.
A market-data interface supplies observations or reference records. An execution interface handles authorized account instructions and confirmed events. They need different permissions and controls; a successful data request does not grant trading authority.
Yes. The developer reference includes local JSON files, a schema and small inspection scripts. There are no account forms or credentials to enter. The files demonstrate data structure, not a production provider contract.
Read the option API guide to understand the layers, choose the market that matches your project, then open the local examples in the documentation. For factual contract details, follow the primary reference linked from the relevant guide.
Go from a market label to a field you can explain. Start with the guides, then inspect the local JSON examples.
