The Copilot family of Chat completion endpoints are used for generating contextual crypto responses using Messari’s knowledge graph and specialized tools. The family offers three endpoint options for generating contextual crypto responses using Messari’s knowledge graph: The OpenAI-compatible endpoint returns data in the standard OpenAI response format, making it compatible with popular SDKs like the OpenAI Python package. This endpoint supports both streaming and synchronous response modes, allowing you to plug directly into packages expecting OpenAI format. The Vercel DSP-compatible endpoint implements the Vercel Data Stream Protocol, enabling direct integration with Vercel’s AI SDK library through the useChat function; it only supports streaming responses. The Messari Format endpoint serves as the standard option but uses Messari’s proprietary format. For most implementations, the OpenAI-compatible endpoint is recommended for its broader compatibility and flexibility.
