Try any of 2778 endpoints — live.
Pick an endpoint, load a working example, tweak the params, and send — no signup to try. Results render the way the data deserves; raw JSON, headers & code are one tab away.
Text-to-speech: turn text into spoken audio (MP3). Pronounces the text in the chosen language's voice/accent — works with every script (Chinese, Japanese, Arabic, Cyrillic, Turkish…). Long text is split and joined into a single MP3. Returns the audio base64-encoded inline (audio/mpeg), so no second download is needed. Pair it with 'translate' to get spoken translations.

What you can run here, without an account
ReefAPI is one HTTP gateway to 438 live web-data APIs covering 2778 endpoints across 14 categories. Every endpoint answers with the same JSON envelope, so one integration reaches all of them. Each response reports what it cost and when the source was read.
No signup, no API key and no card are required to try an endpoint on this page. Anonymous calls run on a shared demo key, capped at 15 calls per hour per visitor. Pick an API, fill the parameters and the real response comes back from the live source, not from a canned sample. A free account lifts the cap and gives you 1,000 credits and your own key.
Browse every API in the catalog, read an endpoint's fields and example response in the docs, or see per-call credit costs on the pricing page.
