Which category do Option Chain, Historical Data & Expired Options Data APIs fall under — Order / Data / Quote / Non-Trading?

Hi @Hardik ,

The API v2 docs’ Rate Limit table lists four categories — Order APIs, Data APIs, Quote APIs, Non-Trading APIs — but the docs never explicitly map each endpoint to its category, so I’d like a precise clarification for these:

  1. Option Chain — POST /optionchain and POST /optionchain/expirylist

  2. Historical Data (candles) — POST /charts/historical and POST /charts/intraday

  3. Expired Options Data — the expired-contract historical endpoints

  4. Market Quote / Live Market Feed / Full Market Depth

For each of the four, please confirm:

  • (a) Which rate-limit category it belongs to (Order / Data / Quote / Non-Trading) — e.g. Option Chain has its own “1 request per 3 seconds” note, so is it a Quote API (1/sec) or a Data API (5/sec, 100,000/day)?

  • (b) Specifically for Expired Options Data — is it covered under the same Data API subscription, and what are its exact rate limits?

The docs sidebar groups Option Chain, Historical Data and Expired Options Data all under “DATA API”, but the rate-limit table’s categories don’t line up one-to-one with the sidebar sections — a definitive endpoint→category→subscription mapping table in the docs would help a lot.

Thanks!
