Privacy-first OpenAI-compatible text embeddings (768 dims) from a local encoder
Privacy-first OpenAI-compatible text embeddings (768 dims) from a local encoder on dedicated hardware - your text never reaches a third-party cloud. Send {"input": string or array of up to 64 texts}; receive standard OpenAI embeddings JSON with usage. Built for RAG, semantic search, dedupe and clustering in agent pipelines. ~2,000-token limit per text. Pay per call in USDC on Base (x402), no API key or account.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
