About API Ninjas
API Ninjas is a collection of ready-made APIs that return data for apps, such as earnings call transcripts and other reference information. It is aimed at teams that want to avoid sourcing and maintaining data themselves.
What it does
Each API returns structured JSON for a specific data need, and the site describes more than 100 of them.

The site also offers an MCP server so that AI assistants such as Claude and ChatGPT can connect to the APIs.
