Rate limits: 60 requests per minute per account, across all its keys, and 1,000 searches per day. A 429 names the limit in data.reason; for minute, retry after Retry-After seconds.
HEAD works wherever GET does, with GET’s status and headers and no body, and counts against the rate limit like GET.
Errors are JSON with code, status, message and sometimes data. Every response except a CORS preflight has an X-Request-Id header; include it when you email us at contact@qaf.ai.
