Best Earnings Calendar APIs for Indian Stocks in 2026
This guide compares APIs for scheduled earnings dates and board-meeting events, not APIs for retrieving filed result statements. For filed results after a meeting, see the Indian earnings API comparison. The date matters: an announced meeting is a schedule; the results filing is a later event.
For a developer-built calendar, Drishti’s upcoming-earnings endpoint is a direct fit for scheduled financial-results events, while NSE and BSE publish exchange calendars and contracted data products. A global earnings calendar can add estimates, but check its Indian-symbol coverage separately. Here are the options and the checks I would make before shipping one.
Quick answer: best Indian earnings calendar APIs
| Option | Best for | Calendar type | Check before choosing |
|---|---|---|---|
| Drishti upcoming earnings | NSE/BSE-focused scheduled result events for watchlists and apps | Financial-results board-meeting events | Date changes, symbol coverage, quarter mapping, and when the actual filing appears |
| NSE Event Calendar | Checking NSE event and board-meeting records | Exchange calendar with company and purpose filters and CSV download | Automated-access and data-use terms; it is a public page, not automatically an API contract |
| BSE Self Data Feed | Contracted BSE calendar and corporate-data access | BSE products, including financial-results calendar | Product availability, KYC, agreement, fields, and delivery |
| Financial Modeling Prep calendar | A cross-market earnings calendar and estimate-oriented workflow | Earnings dates plus EPS/revenue fields in its docs | Confirm the exact NSE/BSE symbol exists and compare its date meaning with exchange filings |
An earnings calendar and an earnings filing feed answer different questions. Use the calendar to plan coverage. Use the filing feed to confirm the report has arrived.
What is an earnings calendar API?
An earnings calendar API returns dates or events associated with company results. Depending on its source, the date may refer to an announced board meeting, a predicted reporting date, or an actual report release. The API should make that meaning clear, or your application should label it conservatively.
For Indian listed companies, the exchange record commonly starts with a board-meeting intimation. NSE’s board-meetings page shows the intimation date and meeting date separately. SEBI’s Regulation 33 filing timeline is a deadline for submitting results, not a promise that every issuer reports on the same calendar day. (SEBI LODR text)
Drishti: best for a watchlist of scheduled result events
Drishti’s GET /v1/earnings/upcoming endpoint returns upcoming event-calendar rows whose purpose mentions financial results. It supports symbol or scrip-code filters, pagination, and quarter information when available. The endpoint excludes a symbol-quarter once a matching earnings filing is present in the latest earnings set.
That behavior is useful for a calendar-to-filing workflow: show an upcoming event, then replace its state with a link to the filed result once one is available. Keep the scheduled event and filed result as separate records, because a meeting can be rescheduled and the result arrives later.
Drishti is a fit when you want to build the calendar into a broader filings, concall, or alert workflow. Review the earnings API docs and the Python SDK before choosing your data model.
NSE: best for checking the exchange event record
NSE’s Corporate Filings Event Calendar lets visitors filter by company and purpose and download CSV. The Board Meetings page gives a straightforward reference for comparing an announced meeting date with an expected-results purpose.
This is useful for analysts and for validating an API integration. If you plan unattended collection or to redistribute exchange data inside a product, confirm the applicable NSE data product and terms. A downloadable CSV is convenient for a person; it does not automatically grant API rights.
BSE: best for a contracted BSE calendar feed
BSE’s Self Data Feed portal lists corporate data through APIs and describes onboarding with registration, KYC, product selection, agreement, and payment. Its information-products sheet lists a financial-results calendar as a product.
Choose this route if BSE coverage and exchange-specific terms are important to your product. Ask for an example response and verify whether it carries a meeting schedule, a filed result, or both. Add your own state labels so a calendar user can see which event has actually happened.
Financial Modeling Prep: best when calendar estimates matter
Financial Modeling Prep documents an Earnings Calendar API with announcement dates and EPS fields, and supports a broad multi-exchange symbol search. That can suit a global company calendar or an application that compares expected and actual estimates.
Do not infer complete NSE/BSE result-date coverage from broad exchange counts. Search for each Indian symbol you need, check the returned exchange and currency, and compare dates with the company’s board-meeting filing. Its earnings calendar is not a substitute for an exchange filing feed or source document.
How to build a calendar that survives earnings season
Store at least three statuses:
| Status | Meaning | Next action |
|---|---|---|
| Scheduled | A company or exchange published a planned meeting | Add it to the watchlist and assign an owner |
| Filed | The result filing is available | Attach the source record and mark the event for review |
| Needs checking | Date changed, duplicate appeared, or expected filing is missing | Keep the previous record and send it to a review queue |
Update the calendar on a schedule, retain date changes, and deduplicate by provider record ID plus company and quarter. Do not delete the earlier event when a new date appears. A small event history makes late changes visible to the team.
For a private implementation, route reminders to email, Slack, or Telegram after the calendar is normalized. The existing filing-alerts Telegram guide covers channel delivery; this article’s focus is the calendar and its event state.
How we compared earnings calendars
We checked each provider’s public documentation for the kind of date returned, symbol filters, exchange coverage, and whether a filed result can be distinguished from a scheduled meeting. We did not measure date accuracy across a historical sample or benchmark update latency. Validate your own company list against exchange notices before using a calendar for time-sensitive alerts.
FAQs about Indian earnings calendars
Is an announced board meeting the same as a result date?
Not necessarily. It is a scheduled meeting to consider a matter such as financial results. Keep the meeting date separate from the actual filing date.
Can NSE or BSE calendars be called directly from my application?
Their public pages have filters and downloads, but that alone does not establish a supported API or reuse permission. Check the relevant exchange data product and terms for automated or customer-facing use.
Should I use a global earnings calendar for NSE and BSE companies?
Only after checking your required symbols. Test a representative set against exchange board-meeting records and source filings, then decide whether the calendar’s coverage and date definitions are acceptable.
What should I do when a result date changes?
Retain the earlier schedule, record the new source and time, update the current date, and notify the people responsible for that company.
Start with the date, then wait for the filing
For an India-focused calendar, test the Drishti upcoming-earnings endpoint against the matching board-meeting record. Then connect the calendar entry to the result filing when it lands.
