API Reference

One page per endpoint. Each page carries the typed signature and a runnable sample in Rust, Python, TypeScript, C++, and HTTP — pick your language once in the tab bar and every page follows — plus the parameter table, the response schema, and (where a captured response exists) example output rows.

Group	Endpoints
Stock	List, snapshots, history (EOD / OHLC / trades / quotes / trade-quote), at-time lookups.
Option	Chain discovery, snapshots, history, Greeks (snapshot, interval, per-trade, EOD), at-time lookups.
Index	List, snapshots, price history, at-time lookups.
Calendar	Trading-calendar status by day and year.
Interest Rate	Rate series history.

Conventions shared by every endpoint — identifiers, units, timestamps — live in Symbology & Contract Identity. Tier badges on each page map to Subscriptions.

Connection setup is one Getting Started away; every sample on these pages assumes a connected client named tdx (client in C++) and runs as-is with only creds.txt present.
