Stock market data APIs, platforms and tools that shut down, 2011–2026
20 products that closed or were discontinued between 2011 and 2026, newest first. Each date comes from the vendor’s own announcement, not from a news story about it; where the notice names only the month, the month is all we print. 12 of them have a page on what to use instead; the rest are here because the date is the fact a reader comes for, and nothing in the catalogue replaces them.
