symbol Quotes

I hope this message finds you well.

I am reaching out regarding a persistent issue I am facing with the FYERS v3 Data API (https://api.fyers.in/data-rest/v3/quotes) while building a live market scanner for F&O stocks.

:red_exclamation_mark:Problem Summary:

  • Every API call to v3/quotes for NSE F&O symbols like NSE:RELIANCE-EQ, NSE:INFY-EQ, etc., returns LTP: None.
  • Response payload structure contains the keys but d[0].v.lp is either missing or null.
  • This happens even during live market hours, with a fresh valid access token (via auth_generate.py).

:hammer_and_wrench: Implementation Details:

  • We’re using Bearer Token Auth with valid access_token from generate_access_token.
  • All API headers and symbol formats are properly constructed (e.g. NSE:TCS-EQ, NSE:SBIN-EQ).
  • Delayed each request by 250ms to avoid rate limits.
  • Verified using Postman and still receiving responses with missing or null LTPs.

:magnifying_glass_tilted_left: Debugging Steps Taken:

  • Verified correct API base URL and token validity.
  • Handled all exceptions and printed full response JSONs.
  • Tried reducing symbol batch size to a single symbol — same result.
  • Manually tested symbols using Postman and browser.

:red_question_mark:Request:

Could you kindly confirm:

  • Whether the v3/quotes endpoint currently supports LTP fetch for F&O stocks individually?
  • Are there any internal issues or known outages today affecting quote retrieval?
  • If the token has additional scopes or access rights needed for real-time data?
  • Is there an alternate recommended endpoint for batch quote fetch (like v2/quotes or WebSocket fallback)?

:warning: Impact:

We are building an automated intraday scanner for trading signals based on real-time data. This issue is blocking all trade signal processing and preventing any use of FYERS data for live decision-making.

We would appreciate your urgent support on this matter.

Hey @nbNiclaW9Q ,

As checked from my side the quotes api is giving proper data , yes we do provide the ltp data in this particular api and you can refer to the key ‘lp’ to receive the last traded price :
