INTEGRATION & TECH STACK FAQ
Questions on Supported AI Technologies.
We integrate with OpenAI (GPT-4o/o3), Anthropic (Claude 3.5 Sonnet/Haiku), Google Gemini 1.5 Pro, Meta Llama 3, and DeepSeek, alongside specialized speech and vision models.
We evaluate your latency, data privacy, compliance, and cost requirements. High-reasoning tasks utilize frontier cloud APIs, while sensitive air-gapped workloads deploy fine-tuned Llama/DeepSeek models locally.
We deploy Pinecone, Qdrant, Milvus, Weaviate, and pgvector (PostgreSQL) for high-performance semantic search and hybrid keyword retrieval.
All integrations utilize zero-data-retention API contracts, encrypted key management vaults, TLS 1.3 encryption, and role-based token scopes.
Yes. We generate custom OpenAPI/Swagger schemas and authentication handlers to connect any internal REST, GraphQL, or gRPC service to your AI agent workforce.
FAQS
API & Integrations
API integration is the process of connecting different software systems so they can securely exchange data and trigger actions.
Yes, we natively integrate the OpenAI API into business systems for advanced reasoning and text generation.
Yes, we build with Google's Gemini API, particularly for multimodal processing and fast-context tasks.
Webhooks are automated messages sent from one app to another when something happens, allowing real-time automation without polling.
API keys are treated as highly sensitive secrets, stored securely in environment variables, and never exposed to the client-side browser.
Systems are designed with exponential backoff and queueing to pause and safely resume requests when API limits are hit.
Yes, if the legacy system has a REST API, SOAP API, or database connection, we can build a bridge to modern AI tools.
Disclaimer: AI systems can produce incorrect outputs. High-impact actions may require validation, permissions or human approval. Third-party API availability can affect workflow execution.
