Official Server SDKs · ipscope Docs

Every official IPScope SDK wraps the REST API with zero-bloat transport, bounded O(1) in-memory LRU caching, automatic batch deduplication, memory-bounded streaming for 10,000+ IP lists, and exponential backoff with jitter on 429 and 5xx responses.

# Compare a single lookup across languages

curl -sS "https://api.ipscope.io/v1/ip/198.51.100.7" \
  -H "Authorization: Bearer $IPSCOPE_KEY"

# What every official SDK guarantees

Scoped strictly to IP intelligence: single IP (/v1/ip/{ip}), caller IP (/v1/ip/me), batch (/v1/ip/batch), network CIDR (/v1/network/{cidr}), dataset catalog (/v1/datasets), and geolocation feedback (/v1/feedback).
Bounded O(1) LRU cache: hot IP addresses are served from memory (2,048 entries by default) and automatically reused across lookupBatch calls so duplicate IPs in a batch never consume quota twice.
Constant-memory batch streaming: lookup_batch_stream / lookupBatchStream chunks arbitrarily large iterables into 100-IP requests with constant < 400 KB heap overhead.
Resilient retry policy: honours Retry-After headers on 429 and retries transient 502/503/504 errors with exponential backoff + jitter.

For air-gapped or local zero-latency lookups, our .mmdb files open directly in standard MaxMind readers in every language. See Reading MMDB.
