How this service works
Text embeddings (768-dim). Send {"input": "text"} or {"input": ["a","b"]}.
Output
Returns a JSON object containing a 'choices' array with the embedding vector(s) (768-dimensional float arrays) for each input text, along with a 'usage' object reporting token counts consumed.
Example use cases
Semantic search over knowledge base
“Embed this user query so I can find the most relevant documents in my vector database: 'What are the side effects of ibuprofen?'”
Sentence similarity scoring
“Get embeddings for both of these sentences so I can measure how similar they are: 'How do I cancel my subscription?' and 'Steps to unsubscribe from a plan.'”
Batch vectorization for RAG pipeline
“Embed all of these product descriptions at once so I can index them for retrieval-augmented generation: ['Wireless noise-cancelling headphones', 'Bluetooth over-ear headset with mic', 'Wired studio monitor headphones'].”
Technical details
Endpoint
POSThttps://river-guestbook-newark-fails.trycloudflare.com/v1/embed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, fast 768-dimensional text embeddings for semantic search, clustering, or similarity tasks, especially in agentic pipelines that support x402 micropayment authentication. The 768-dim output is compatible with many standard vector stores (Pinecone, Weaviate, Qdrant). Avoid if you need higher-dimensional embeddings (e.g. 1536-dim OpenAI style) or if you require a guaranteed SLA from a named commercial provider.
Side effects
- Empty or missing 'input' field returns an error
- Input text exceeding token limit may be truncated or rejected
- Malformed JSON body returns 400-level error
- Temporary Cloudflare tunnel unavailability returns 5xx or connection timeout
- Payment failure or insufficient USDC balance blocks the request
