Rate limits

120 requests per minute per IP, with a burst of 30. This is far more than a normal integration needs, and it exists to stop abuse rather than to meter usage.
Exceeding it returns 429 Too Many Requests with a Retry-After: 60 header and a small JSON body.
Because responses are cacheable for a minute, caching on your side is the easiest way to stay well inside the limit.

Caching and freshness

Responses carry Cache-Control: public, max-age=60, stale-while-revalidate=300, so caching for a minute is safe.
Each service is polled every 5 minutes while healthy, and every minute while it is having problems. Data can therefore be up to 5 minutes old.
changedAt is when the status last changed, which can be much older than lastPolledAt.

Suggesting a service

If a service is missing, the website offers to suggest it. That form posts to POST /api/v1/suggest with { "name": "...", "url": "..." }, where the url is optional, and turns the suggestion into a GitHub issue. It is rate limited much more tightly than the read endpoints.

Terms

Free to use, including commercially. Please cache rather than polling aggressively, and link back to https://downradar.info where it makes sense. The data comes from each service's own status page, so treat it as a convenience rather than a contract.
