Terms. Embedding is free. Attribution is appreciated but not required. Rate limit on the free tier is 60 req/min/IP — embed widgets refresh on a 60-second timer so a single embed is one request per minute, comfortably under the cap. If you're embedding on a high-traffic page (>1000 simultaneous viewers), get in touch and I'll set you up with a higher-quota key.
