Spyfu Rate Limits

SpyFu enforces per-endpoint rate limits on a rolling 1-second window. Limits vary by endpoint according to relative compute cost, from 2 requests/second on the Top Pages endpoints to 1000 requests/second on Domain Stats and Competitors. Exceeding a limit returns HTTP 429 Too Many Requests with a Retry-After header (typically 1) and a JSON body of {"error":"rate_limited","message":"Too many requests. Please retry after 1 second."}. There are no RateLimit-* / X-RateLimit-* quota headers on successful responses, so a client cannot observe how close it is to a limit — the only runtime signal arrives after the limit is already breached. There are no daily or monthly request quotas; volume is metered commercially through the per-row API credit system instead (see finops/spyfu-finops.yml).
