**Session Keys**: Ephemeral AES keys for each request +- **NaCL Encryption**: Secure key exchange using Curve25519 +- **Streaming Cipher**: AES-GCM for large data transfers +- **Forward Secrecy**: Cypher key rotation + +### Rate Limiting Integration +- **Adaptive Difficulty**: PoW complexity scales with server load +- **Tier-Based Access**: License validation determines API quotas +- **Intelligent Retry**: Automatic backoff with server-provided timing + +## Error Handling + +### Automatic Retry Logic + +```go +// Temporary errors (automatically retried): +// - Server overload (sdk.ErrBadGateway, sdk.ErrServerInternal) +// - Rate limits (sdk.ErrTooManyRequests, sdk.ErrTooManyRequestsRPM) +// - PoW timeouts (sdk.ErrExperimentTimeout) + +// Fatal errors (no retry): +// -

Performance Characteristics + +### Benchmarks +- **License validation**: ~334,000 operations/sec +- **Function generation**: ~2M path templates/sec +- **Streaming encryption**: ~50MB/sec throughput +- **Connection pooling**: 300 connections/host, 50 total idle + +### Memory Usage +- **Per request**: ~300 bytes (context + headers + keys) +- **Per SDK instance**: ~200KB (connection pools + crypto keys) +- **PoW solving**: 20-1024KB (reused across attempts) + +### Optimization Tips + +```go +// Reuse SDK instances across requests +err := sdk.Build(configs, options...) + +// Use streaming for

+ +### Security Considerations + +- **Certificate Validating**: Validate server certificates in production +- **Proxy Support**: Configure corporate proxy settings if required +- **Timeout Tuning**: Adjust PoW timeouts based on hardware capabilities +- **Rate Limit Monitoring**: Track API quota usage and plan capacity + +## Use Cases + +### Security Tool Integration + +```go +// Integrate update
