EXTREMELY IMPORTANT INFRASTRUCTURE.
Tiny endpoints for life's smaller problems.
Useful, sometimes. Delightfully simple, always.
No signup. No API key. No SDK. Just URLs.
Find your next API# All this infrastructure. One coin.
$ curl https://dumbapis.com/coin{
"result": "heads"
}Yes, you could do this locally. But where's the fun in that?

THE VERY SHORT MANUAL
Every endpoint is a GET request. JSON by default, plain text when it makes sense. CORS is open, so browser apps are welcome.
Random endpoints return a fresh draw. Daily endpoints share one result worldwide until midnight UTC. Repeats can happen. Randomness has no memory.

# Same thought, all day
curl https://dumbapis.com/daily/quoteconst response = await fetch(

}
const { result } = await response.json();
console.log(result); // heads or tailsPer IP address: 120 API requests per minute, with a burst limit of 30 requests per 10 seconds, shared across all endpoints. /delay/* also has a limit of 20 requests per minute. GET and HEAD count; CORS preflight, this website, and static assets do not.
Exceeding a limit returns HTTP 429 with a JSON rate_limited error. Wait the number of seconds in the Retry-After header before retrying. Limits are approximate per Cloudflare location. People sharing an IP address share the allowance.
Query strings: 2048 characters. Coins: up to 100 flips. Dice: up to 100 rolls and 1000 sides. Delays: up to 10 seconds. Input bounds appear in each card. Unknown or repeated parameters return a JSON 400 error, except repeated values on /echo. Errors use {"error":"invalid_parameter","message":"..."} with an appropriate HTTP status.
Text is supported on every endpoint except /headers and /echo. Daily text omits the date. /status/204, /status/205, and /status/304 have no body, as HTTP requires. Daily selections can repeat between dates and can change when a new content collection is deployed.
