            npx siteanalyzerfree checkup example.com --json

# Or install globally:

            npm install -g siteanalyzerfree

            siteanalyzerfree ai-readiness example.com --json

Rate Limits & Real-Time Throttling

To allow autonomous agents and automated workflows to self-throttle without trial-and-error, every API response emits standard IETF RFC RateLimit headers:

RateLimit-Limit

120 req/min

Maximum requests per sliding 60-second window.

RateLimit-Remaining

Dynamic

Remaining requests available before throttling.

RateLimit-Reset

Seconds

Seconds until current window resets.

Retry-After

On HTTP 429

Exact seconds an agent should sleep before retrying.

Also includes backward-compatible X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset headers. On HTTP 429, a structured JSON error body with code RATE_LIMIT_EXCEEDED is returned.
