Ceres Client - HTTP clients for external APIs

This crate provides HTTP clients for interacting with:

• ckan - CKAN open data portals
• portal - Unified portal client factory (enum dispatch over portal types)
• gemini - Google Gemini embeddings API
• openai - OpenAI embeddings API
• ollama - Ollama local embeddings

Overview

The clients handle authentication, request building, response parsing, and error handling for their respective APIs.

Multiple portal types are supported via PortalClientEnum:

Portal Type	Status	API
CKAN	Supported	CKAN API
DCAT-AP (udata REST)	Supported	DCAT-AP
Socrata	Planned	Socrata API

Embedding Providers

Provider	Model	Dimensions
Gemini	gemini-embedding-001	768
OpenAI	text-embedding-3-small	1536
OpenAI	text-embedding-3-large	3072
Ollama	nomic-embed-text	768
Ollama	mxbai-embed-large	1024
