Instruments & Trading Venues
We are in open beta
This page gives you a detailed description of all endpoints related to Instruments and Trading Venues. These endpoints are part of the Market Data API, therefore use the following base URL for your request:
https://data.lemon.markets/v1/
The instrument endpoint allows to search through all offered instruments. Instruments are equities that are tradable on lemon.markets. The instruments endpoint lets you identify relevant instruments that you can then integrate into your brokerage product.
This endpoint returns a list of instruments, based on the search criteria or filter you provided in your query parameters. To use the endpoint, use the following request URL:

How do we determine whether an Instrument is tradable?
Twice a day, we check with Gettex whether an Instrument is tradable - once right before the exchange opens and around 3:35pm when NASDAQ opens. Based on that check, we update our Instruments list.
