Jina AI vs TensorFeed
Jina AI provides token-billed APIs for multilingual, multimodal embeddings, a reranker for search relevance, and the Reader endpoint (r.jina.ai) that converts any URL into clean Markdown for LLM grounding. New accounts get an auto-generated API key with a ten-million-token free trial before moving to paid rate tiers (100 RPM/100K TPM free, up to 5,000 RPM/50M TPM on the top plan). Recent additions include an Elasticsearch-native inference plugin and MCP/CLI integrations for agent workflows.
TensorFeed is a free, no-auth JSON API for AI-industry data: real-time model pricing, provider status/outage monitoring (polled every 2 minutes), AI news, and agent-activity feeds, plus an in-browser API playground for every free endpoint. It also publishes an x402-based Premium Agent API (USDC on Base, no accounts or keys) for ranked model-routing recommendations, and self-certifies under its own "Agent Fair-Trade" standard with Ed25519-signed receipts and code-enforced no-charge on failed calls. Live-checked in July 2026: the site, its free endpoints, and CORS support are all confirmed working.
