Live prices for one market, by account identifier and epic: the bid and ask ladder up to five tiers deep, the sizes at each tier, the day's high and low and the dealing state. IG's page says price availability depends on the account's permissions.
Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

This is a subscription of the IG Streaming API, not an HTTP endpoint. It has no method and no path: it travels over a Lightstreamer connection that stays open, which a Lightstreamer client library manages.
The same page marks the older MARKET:{epic} subscription, and its alias L1, as deprecated in favour of this one: it gives 1 May 2026 as its end of life and 8 May 2026 as the date it is decommissioned. This site does not record MARKET for that reason.

IG's Streaming API Guide (labs.ig.com/streaming-api-guide.html), opened the same day, says the server address is the Lightstreamer address returned by the REST /session call and should not be hard coded, that the user is the active account identifier, and that the password is built from the CST and X-SECURITY-TOKEN tokens of the REST session. It gives 40 as the default number of simultaneous subscriptions on one connection.
