Offendersearch Api Rate Limits

Requests are rate limited per API key. The documentation publishes the runtime signal — X-RateLimit-Limit / X-RateLimit-Remaining / X-RateLimit-Reset on every response and Retry-After on a 429 — but does NOT publish the numeric ceiling: sustained rate, concurrency and monthly volume are described as "set by your plan" and are not stated anywhere public. Because pricing is purely metered with no tiers, there is no published per-tier limit table to read. Guidance for large jobs is to use the asynchronous endpoint or batch rather than issuing thousands of synchronous calls, and to back off exponentially respecting Retry-After.
