get_playground_apis
shallowio.apis/apis-io · Verify this server
Curated APIs that are SAFE TO EXPERIMENT WITH — no key (or an instant, free, self-serve key), no cost, and no real-world side effects. Every entry carries an `example_request` URL that returned HTTP 200 to an unauthenticated GET on the date shown, so it can be called immediately with no setup. Use this when you are new to this catalog, learning what an API call feels like, testing a tool-use loop, or need a harmless endpoint to demonstrate something. Defaults to the `starter` set; pass grouping="deep-archive" for institutional/OAI-PMH repositories.
